ACPI: Clean up inclusions of ACPI header files Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

device.h: audit and cleanup users in main include dir The <linux/device.h> header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

block,ide: simplify bdops->set_capacity() to ->unlock_native_capacity() bdops->set_capacity() is unnecessarily generic. All that's required is a simple one way notification to lower level driver telling it to try to unlock native capacity. There's no reason to pass in target capacity or return the new capacity. The former is always the inherent native capacity and the latter can be handled via the usual device resize / revalidation path. In fact, the current API is always used that way. Replace ->set_capacity() with ->unlock_native_capacity() which take only @disk and doesn't return anything. IDE which is the only current user of the API is converted accordingly.

ide: Requeue request after DMA timeout I noticed that my KVM virtual machines were experiencing IDE issues resulting in processes stuck on waiting for buffers to complete. The root cause is of course race conditions in the ancient qemu backend that I'm using. However, the fact that the guest isn't recovering is a bug. I've tracked it down to the change made last year to dequeue requests at the start rather than at the end in the IDE layer. commit 8f6205cd572fece673da0255d74843680f67f879 Author: Tejun Heo <tj@kernel.org> Date: Fri May 8 11:53:59 2009 +0900 ide: dequeue in-flight request The problem is that the function ide_dma_timeout_retry does not requeue the current request, causing one request to be lost for each DMA timeout. This patch fixes this by requeueing the request. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

[ As discovered by detective work by Frans and Bart, due to how handling of the ID block was handled before commit c419993 ("ide-iops: only clear DMA words on setting DMA mode") this check was always seeing zeros in the fields or other similar garbage. Therefore this check wasn't actually checking anything. Now that the tests actually check the real bits, all we see are devices that trigger the check yet work perfectly fine, therefore killing this useless check is the best thing to do. -DaveM ] Reported-by: Frans Pop <elendil@planet.nl> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S.

ide: preserve Host Protected Area by default (v2) From the perspective of most users of recent systems, disabling Host Protected Area (HPA) can break vendor RAID formats, GPT partitions and risks corrupting firmware or overwriting vendor system recovery tools. Unfortunately the original (kernels < 2.6.30) behavior (unconditionally disabling HPA and using full disk capacity) was introduced at the time when the main use of HPA was to make the drive look small enough for the BIOS to allow the system to boot with large capacity drives. Thus to allow the maximum compatibility with the existing setups (using HPA and partitioned with HPA disabled) we automically disable HPA if any partitions overlapping HPA are detected. Additionally HPA can also be disabled using the "nohpa" module parameter (i.e. "ide_core.nohpa=0.0" to disable HPA on /dev/hda). v2: Fix ->resume HPA support.

ide: unify interrupt reason checking Add ide_check_ireason() function that handles all ATAPI devices. Reorganize all unlikely cases in ireason checking further down in the code path. In addition, add PFX for printks originating from ide-atapi. Finally, remove ide_cd_check_ireason. Signed-off-by: Borislav Petkov <petkovbb@gmail.com>

ide-atapi: add a buffer-arg to ide_queue_pc_tail This is in preparation of removing ide_atapi_pc. Expose the buffer as an argument to ide_queue_pc_tail with later replacing it with local buffer or even kmalloc'ed one if needed due to stack usage constraints. Also, add the possibility of passing a NULL-ptr buffer for cmds which don't transfer data besides the cdb. While at it, switch to local buffer in idetape_get_mode_sense_results(). There should be no functional change resulting from this patch. Signed-off-by: Borislav Petkov <petkovbb@gmail.com>

ide-cd,atapi: use bio for internal commands Impact: unify request data buffer handling rq->data is used mostly to pass kernel buffer through request queue without using bio. There are only a couple of places which still do this in kernel and converting to bio isn't difficult. This patch converts ide-cd and atapi to use bio instead of rq->data for request sense and internal pc commands. With previous change to unify sense request handling, this is relatively easily achieved by adding blk_rq_map_kern() during sense_rq prep and PC issue. If blk_rq_map_kern() fails for sense, the error is deferred till sense issue and aborts the failed command which triggered the sense. Note that this is a slim possibility as sense prep is done on each command issue, so for the above condition to actually trigger, all preps since the last sense issue till the issue of the request which would require a sense should fail. * do_request functions might sleep now. This should be okay as ide request_fn - do_ide_request() - is invoked only from make_request and plug work. Make sure this is the case by adding might_sleep() to do_ide_request(). * Functions which access the read sense data before the sense request is complete now should access bio_data(sense_rq->bio) as the sense buffer might have been copied during blk_rq_map_kern(). * ide-tape updated to map sg. * cdrom_do_block_pc() now doesn't have to deal with REQ_TYPE_ATA_PC special case. Simplified. * tp_ops->output/input_data path dropped from ide_pc_intr(). Signed-off-by: Tejun Heo <tj@kernel.org>

ide: fix refcounting in device drivers During host driver module removal del_gendisk() results in a final put on drive->gendev and freeing the drive by drive_release_dev(). Convert device drivers from using struct kref to use struct device so device driver's object holds reference on ->gendev and prevents drive from prematurely going away. Also fix ->remove methods to not erroneously drop reference on a host driver by using only put_device() instead of ide*_put().

Remove HPT_SERIALIZE_IO while at it. * Set IDE_HFLAG_SERIALIZE in ->host_flags if needed in ide_init_port(). * Convert init_irq() to use IDE_HFLAG_SERIALIZE together with hwif->host to find out ports which need to be serialized. * Remove no longer needed save_match() and ide_hwif_t.serialized. v2: * Set host's ->host_flags field instead of port's copy. This patch should fix the incorrect grouping of port(s) from host(s) that need serialization with port(s) that happen to use the same IRQ(s) but are from the host(s) that don't need it.

ide: replace the global ide_lock spinlock by per-hwgroup spinlocks (v2) Now that (almost) all host drivers have been fixed not to abuse ide_lock and core code usage of ide_lock has been sanitized we may safely replace ide_lock by per-hwgroup locks. This patch is partially based on earlier patch from Ravikiran G Thirumalai. While at it: - don't use deprecated HWIF() and HWGROUP() macros - update locking documentation in ide.h v2: Add missing spin_lock_init(&hwgroup->lock). (Noticed by Elias Oltmanns) Cc: Vaibhav V.

amd74xx: workaround unreliable AltStatus register for nVidia controllers It seems that on some nVidia controllers using AltStatus register can be unreliable so default to Status register if the PCI device is in Compatibility Mode. In order to achieve this: * Add ide_pci_is_in_compatibility_mode() inline helper to <linux/ide.h>. * Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host driver for nVidia controllers in Compatibility Mode. * Teach actual_try_to_identify() and drive_is_ready() about the new flag. This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ config option in 2.6.25 and using AltStatus register unconditionally when available (kernel.org bugs #11659 and #10216). [ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people and distributions use) it never worked correctly. ] Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.

ide: Implement disk shock protection support (v4) On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD FEATURE as specified in ATA-7 is issued to the device and processing of the request queue is stopped thereafter until the specified timeout expires or user space asks to resume normal operation. This is supposed to prevent the heads of a hard drive from accidentally crashing onto the platter when a heavy shock is anticipated (like a falling laptop expected to hit the floor). Port resets are deferred whenever a device on that port is in the parked state. v3: Elias Oltmanns <eo@nebensachen.de> wrote: [...] > >> 1. Make sure that no negative value is being passed to > >> jiffies_to_msecs() in ide_park_show(). > >> 2. Drop the superfluous variable hwif in ide_special_rq(). > >> 3.

Additionally, we should plug the queue when enqueueing the unpark request because there is no guarantee that the park timeout has not expired by then. Even though the chance for that to happen is very slim, the request might end up hanging in the queue until the next I/O operation is queued up. While at it, clean up the code a little: - make issue_park_cmd() a function of type void since nobody cares for the return value anyway; - use blk_start_queueing() instead of __blk_run_queue() since we don't have to worry about recursion; - remove a superfluous pointer deference in task_no_data_intr().

ide: remove drive->driveid * Factor out HDIO_[OBSOLETE,GET]_IDENTITY ioctls handling to ide_get_identity_ioctl(). * Use temporary buffer in ide_get_identity_ioctl() instead of accessing drive->id directly. * Add ide_id_to_hd_driveid() inline to convert raw id into struct hd_driveid format (needed on big-endian). * Use ide_id_to_hd_driveid() in ide_get_identity_ioctl(), cleanup ide_fix_driveid() and switch ide to use use raw id. * Remove no longer needed drive->driveid. This leaves us with 3 users of struct hd_driveid in tree: - arch/um/drivers/ubd_kern.c - drivers/block/xsysace.c - drivers/usb/storage/isd200.c While at it: * Use ata_id_u{32,64}() and ata_id_has_{dma,lba,iordy}() macros.

ide: make drive->id an union (take 2) Make drive->id an unnamed union so id can be accessed either by using 'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing drive->id users accordingly (using 'u16 *id' when possible). This is an intermediate step to make ide 'struct hd_driveid'-free. While at it: - Add missing KERN_CONTs in it821x.c. - Use ATA_ID_WORDS and ATA_ID_*_LEN defines. - Remove unnecessary checks for drive->id. - s/drive_table/table/ in ide_in_drive_list(). - Cleanup ide_config_drive_speed() a bit. - s/drive1/dev1/ & s/drive0/dev0/ in ide_undecoded_slave(). v2: Fix typo in drivers/ide/ppc/pmac.c.

Allowing "default" transfer mode values is a dangerous thing to do as we don't support programming controller to the "default" transfer mode and devices often use different values for the default and maximum PIO mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay programmed for higher PIO mode while device will use the lower PIO mode. There is no functionality loss as by using special IOCTLs device can still be programmed to "default" transfer modes (it is only useful for debugging/testing purposes anyway). * Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was previously used by few host drivers to program the controller to PIO0 timings for "default" transfer mode == 0x01 (although some host drivers would program invalid PIO timings instead). * Cleanup ide_set_xfer_rate() and add BUG_ON().

IDE: Fix HDIO_DRIVE_RESET handling Currently, the code path executing an HDIO_DRIVE_RESET ioctl is broken in various ways. Most importantly, it is treated as an out of band request in an illegal way which may very likely lead to system lock ups. Use the drive's request queue to avoid this problem (and fix a locking issue for free along the way).

ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3) hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS and given the number of bugs we can assume that there are no real users: * DMA has no chance of working because DMA resources are released by ide_unregister() and they are never allocated again. * Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls don't work for almost all hosts with "non-standard" (== non ISA-like) layout of IDE taskfile registers (there is a lot of such host drivers). * ide_port_init_devices() is not called when probing IDE devices so: - drive->autotune is never set and IDE host/devices are not programmed for the correct PIO/DMA transfer modes (=> possible data corruption) - host specific I/O 32-bit and IRQ unmasking settings are not applied (=> possible data corruption) - host specific ->port_init_devs method is not called (=> no luck with ht6560b, qd65xx and opti621 host drivers) * ->rw_disk method is not preserved (=> no HPT3xxN chipsets support). * ->serialized flag is not preserved (=> possible data corruption when using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366 (HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers). * ->ack_intr method is not preserved (=> needed by ide-cris, buddha, gayle and macide host drivers). * ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it isn't initialized again (SiI3112 support needs them). * To issue an ioctl() there need to be at least one IDE device present in the system. * ->cable_detect method is not preserved + it is not called when probing IDE devices so cable detection is broken (however since DMA support is also broken it doesn't really matter ;-). * Some objects which may have already been freed in ide_unregister() are restored by ide_hwif_restore() (i.e. ->hwgroup). * ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[] slot cannot be found. * When IDE host drivers are modular unregistered port may be re-used by different host driver that owned it first causing subtle bugs. Since we now have a proper warm-plug support remove these ioctls, then remove no longer needed: - ide_register_hw() and ide_hwif_restore() functions - 'init_default' and 'restore' arguments of ide_unregister() - zeroeing of hwif->{dma,extra}_* fields in ide_unregister() As an added bonus IDE core code size shrinks by ~3kB (x86-32). v2: * fix ide_unregister() arguments in cleanup_module() (Andrew Morton). v3: * fix ide_unregister() arguments in palm_bk3710.c.

ide: remove dead/obsolete ->busproc method ->busproc method is used by HDIO_SET_BUSSTATE ioctl but it has no chance of working as intended (in 2.4.x days) because to issue an ioctl there is a device node needed and: - for BUSSTATE_TRISTATE+OFF it is too late (devices are already gone) - for BUSSTATE_TRISTATE+ON it is too early (devices are not registered yet) Just remove ->busproc method for now (it was only implemented by hpt366, siimage and tc86c001 host drivers).

ide-disk: fix flush requests (take 2) commit 813a0eb233ee67d7166241a8b389b6a76f2247f9 Author: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Date: Fri Jan 25 22:17:10 2008 +0100 ide: switch idedisk_prepare_flush() to use REQ_TYPE_ATA_TASKFILE requests ... broke flush requests. Allocating IDE command structure on the stack for flush requests is not a very brilliant idea: - idedisk_prepare_flush() only prepares the request and it doesn't wait for it to be completed - there are can be multiple flush requests queued in the queue Fix the problem (per hints from James Bottomley) by: - dynamically allocating ide_task_t instance using kmalloc(..., GFP_ATOMIC) - adding new taskfile flag (IDE_TFLAG_DYN) - calling kfree() in ide_end_drive_command() if IDE_TFLAG_DYN is set (while at it rename 'args' to 'task' and fix whitespace damage) [ This will be fixed properly before 2.6.25 but this bug is rather critical and the proper solution requires some more work + testing. ] Thanks to Sebastian Siewior and Christoph Hellwig for reporting the problem and testing patches (extra thanks to Sebastian for bisecting it to the guilty commmit).

Check the flag in do_rw_taskfile() and set handler accordingly. * Cleanup ide_init_{specify,restore,setmult}_cmd() and rename it to ide_tf_set_{specify,restore,setmult}_cmd(). * Make {set_geometry,recal,set_multmode}_intr() static. * Remove no longer needed 'handler' field from ide_task_t. v2: * 'handler' in do_rw_taskfile() must be set to NULL initially.

Since for IDE PMAC host driver IDE_CONTROL_REG is always true, device's ->quirk_list is always zero and ->ide_dma_host_{on,off} are nops than the only changes in behavior are: * if PIO mode is set then ->dma_off_queitly is called to disable DMA * if setting transfer mode fails ide_dump_status() is called to dump status v2: * IDE PMAC controllers allow separate PIO and DMA timings and PPC userland depends on this fact, and calls "hdparm -p" without calling "hdparm -d". Therefore to compensate for DMA being disabled by ide_config_drive_speed() for PIO modes: - add IDE_HFLAG_SET_PIO_MODE_KEEP_DMA flag and set it in PMAC host driver - add handling of the new flag to ide-io.c::do_special() Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Also add inline ide_find_dma_mode() version for CONFIG_BLK_DEV_IDEDMA=n case. * Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask() to avoid false warning from eighty_ninty_three(). * Use ide_find_dma_mode() to limit the user requested transfer mode in ide_rate_filter(). Also limit the requested mode by host max PIO mode. Above changes make ide_rate_filter() to: * Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19 and 0x25-0x39, values > 0x46 were already clipped down, same for values 0x25-0x39 but iff UDMA was not supported by the host). * Clip desired transfer mode down if it is currently unsupported by IDE core (PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was not supported by the host). * Clip desired transfer mode down according to the host capabilities (UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't, also ->atapi_dma flag was not respected). * Clip desired transfer mode down according to the device capabilities (except PIO modes for now which require mode work) - shouldn't be a problem since ide_set_xfer_rate() is called _after_ device has accepted given transfer mode. and also result in a number of host driver specific bugfixes: * icside - clip unsupported PIO5 mode down - fix unsupported/invalid modes being set in drive->current_speed * ide-cris - clip unsupported PIO5 and SWDMA0-2 modes down - clip DMA modes down for ATAPI devices - fix BUG() on unsupported/invalid modes * au1xxx-ide -

ide: legacy PCI bus order probing fixes IDE PCI host drivers should register themselves with IDE core only when IDE driver is built-in, otherwise (IDE driver is modular and thus IDE PCI host drivers are also modular) the code has no effect and just complicates the probing. Fix it by adding new config option CONFIG_IDEPCI_PCIBUS (defined only when needed and invisible to the user) and covering by #ifdef/#endif the code in question.

sl82c105: rework PIO support (take 2) Get rid of the 'pio_speed' member of 'ide_drive_t' that was only used by this driver by storing the PIO mode timings in the 'drive_data' instead -- this allows us to greatly simplify the process of "reloading" of the chip's timing register and do it right in sl82c150_dma_off_quietly() and to get rid of two extra arguments to config_for_pio() -- which got renamed to sl82c105_tune_pio() and now returns a PIO mode selected, with ide_config_drive_speed() call moved into the tuneproc() method, now called sl82c105_tune_drive() with the code to set drive's 'io_32bit' and 'unmask' flags in its turn moved to its proper place in the init_hwif() method. Also, while at it, rename get_timing_sl82c105() into get_pio_timings() and get rid of the code in it clamping cycle counts to 32 which was both incorrect and never executed anyway...

ide: correctly prevent IDE timer expiry function to run if request was already handled It is possible for the timer expiry function to run even though the request has already been handled: ide_timer_expiry() only checks that the handler is not NULL, but it is possible that we have handled a request (thus clearing the handler) and then started a new request (thus starting the timer again, and setting a handler). A simple way to exhibit this is to set the DMA timeout to 1 jiffy and run dd: The kernel will panic after a few minutes because ide_timer_expiry() tries to add a timer when it's already active. To fix this, we simply add a request generation count that gets incremented at every interrupt, and check in ide_timer_expiry() that we have not already handled a new interrupt before running the expiry function.

ide: use correct IDE error recovery IDE error recovery is using IDLE IMMEDIATE if the drive is busy or has DRQ set. This violates the ATA spec (can only send IDLE IMMEDIATE when drive is not busy) and really hoses up some drives (modern drives will not be able to recover using this error handling). The correct thing to do is issue a SRST followed by a SET FEATURES command. This is what Western Digital recommends for error recovery and what Western Digital says Windows does.  It also does not violate the ATA spec as far as I can tell. Bart: * port the patch over the current tree * undo the recalibration code removal * send SET FEATURES command after checking for good drive status * don't check whether the current request is of REQ_TYPE_ATA_{CMD,TASK} type because we need to send SET FEATURES before handling any requests * some pre-ATA4 drives require INITIALIZE DEVICE PARAMETERS command before other commands (except IDENTIFY) so send SET FEATURES only if there are no pending drive->special requests * update comments and patch description * any bugs introduced by this patch are mine and not Suleiman's :-) Signed-off-by: Suleiman Souhlal <suleiman@google.com> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

ACPI support for IDE devices This patch implements ACPI integration for generic IDE devices. The ACPI spec mandates that some methods are called during suspend and resume. And consequently there most modern Laptops cannot resume properly without it. According to the spec, we should call '_GTM' (Get Timing) upon suspend to store the current IDE adapter settings. Upon resume we should call '_STM' (Set Timing) to initialize the adapter with the stored settings; afterwards '_GTF' (Get Taskfile) should be called which returns a buffer with some IDE initialisation commands. Those commands should be passed to the drive. There are two module params which control the behaviour of this patch: 'ide=noacpi' Do not call any ACPI methods (Disables any ACPI method calls) 'ide=acpigtf' Enable execution of _GTF methods upon resume. Has no effect if 'ide=noacpi' is set. 'ide=acpionboot' Enable execution of ACPI methods during boot. This might be required on some machines if 'ide=acpigtf' is selected as some machines modify the _GTF information depending on the drive identification passed down with _STM.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

[PATCH] IDE CD end-of media error fix This is a patch from Alan that fixes a real ide-cd.c regression causing bogus "Media Check" failures for perfectly valid Fedora install ISOs, on certain CD-ROM drives. This is a forward port to 2.6.16 (from RHEL) of the minimal changes for the end of media problem. It may not be sufficient for some controllers (promise notably) and it does not touch the locking so the error path locking is as horked as in mainstream. From: Ingo Molnar <mingo@elte.hu> I have ported the patch to 2.6.17-rc4 and tested it by provoking end-of-media IO errors with an unaligned ISO image. Unlike the vanilla kernel, the patched kernel interpreted the error condition correctly with 512 byte granularity: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown ATAPI device hdc: Error: Illegal request -- (Sense key=0x05) Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00) The failed "Read 10" packet command was: "28 00 00 04 fb 78 00 00 06 00 00 00 00 00 00 00 " end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 Buffer I/O error on device hdc, logical block 163261 Buffer I/O error on device hdc, logical block 163262 the unpatched kernel produces an incorrect error dump: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306088 Buffer I/O error on device hdc, logical block 163261 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306096 Buffer I/O error on device hdc, logical block 163262 I do not have the right type of CD-ROM drive to reproduce the end-of-media data corruption bug myself, but this same patch in RHEL solved it.

[PATCH] stop CompactFlash devices being marked as removable This patch stops CompactFlash devices being marked as removable. They are not removable (as defined by Linux) as the media and device are inseparable. When a card is removed, the whole device is removed from the system and never sits in a media-less state. This stops some nasty udev device creation/destruction loops. Further, once this change is made, there is no need for ide to can be removed from ide_drive_t.

[PATCH] Change maxaligned_in_smp alignemnt macros to internodealigned_in_smp macros ____cacheline_maxaligned_in_smp is currently used to align critical structures and avoid false sharing. It uses per-arch L1_CACHE_SHIFT_MAX and people find L1_CACHE_SHIFT_MAX useless. However, we have been using ____cacheline_maxaligned_in_smp to align structures on the internode cacheline size. As per Andi's suggestion, following patch kills ____cacheline_maxaligned_in_smp and introduces INTERNODE_CACHE_SHIFT, which defaults to L1_CACHE_SHIFT for all arches. Arches needing L3/Internode cacheline alignment can define INTERNODE_CACHE_SHIFT in the arch asm/cache.h. Patch replaces ____cacheline_maxaligned_in_smp with ____cacheline_internodealigned_in_smp With this patch, L1_CACHE_SHIFT_MAX can be killed Signed-off-by: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Shai Fultheim <shai@scalex86.org> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
