iwlwifi: fix skb truesize underestimation
By default, iwlwifi uses order-1 pages (8 KB) to store incoming frames,
but doesnt say so in skb->truesize.
This makes very possible to exhaust kernel memory since these skb evade
normal socket memory accounting.
As struct ieee80211_hdr is going to be pulled before calling IP stack,
there is no need to use dev_alloc_skb() to reserve NET_SKB_PAD bytes.
alloc_skb() is ok in this driver, allowing more tailroom.
Pull beginning of frame in skb header, in the hope we can reuse order-1
pages in the driver immediately for small frames and reduce their
truesize to the minimum (linear skbs)

iwlwifi: abstract out missing SEQ_RX_FRAME workaround
Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround
warning with a statistics notification, this means we
can't just remove it as we'd hoped.
Abstract it out so that the higher layer can configure
this as a kind of "filter" in the transport.

What is needed mmiowb(), for synchronizing writes coming from

fortunately is not needed on x86, where mmiowb() is just
defined as compiler barrier. As iwlwifi devices are most likely

Now the op_mode has a fw pointer, and
(unfortunately) for now the shared data
also needs to keep one for the transport
to access dump the error log -- I think
that will move later.
Since I wanted to constify the firmware
pointers, some more changes were needed.

iwlwifi: fix PCI-E transport "inta" race
When an interrupt comes in, we read the reason
bits and collect them into "trans_pcie->inta".
This happens with the spinlock held. However,
there's a bug resetting this variable -- that
happens after the spinlock has been released.
This means that it is possible for interrupts
to be missed if the reset happens after some
other interrupt reasons were already added to
the variable.
I found this by code inspection, looking for a
reason that we sometimes see random commands
time out. It seems possible that this causes
such behaviour, but I can't say for sure right
now since it happens extremely infrequently on
my test systems.

iwlagn: fix (remove) use of PAGE_SIZE
The ICT code erroneously uses PAGE_SIZE. The bug
is that PAGE_SIZE isn't necessarily 4096, so on
such platforms this code will not work correctly
as we'll try to attempt to read an index in the
table that the device never wrote, it always has
4096-byte pages.
Additionally, the manual alignment code here is
unnecessary -- Documentation/DMA-API-HOWTO.txt
states:
The cpu return address and the DMA bus master address are both
guaranteed to be aligned to the smallest PAGE_SIZE order which
is greater than or equal to the requested size. This invariant
exists (for example) to guarantee that if you allocate a chunk
which is smaller than or equal to 64 kilobytes, the extent of the
buffer you receive will not cross a 64K boundary.
Just use appropriate new constants and get rid of
the alignment code.

iwlwifi: Display more uCode debug info
When uCode encounter problem, it pass a lot of debug data to help debugging
the issue. We only show partial data before, why not display all of those.

iwlagn: remove the callback in host commands
Before this patch, the upper layer could register a callback for each
host command. This mechanism allowed the upper layer to have
different callbacks for the same command ID. In fact, it wasn't used
and the rx_handlers is enough: same callback for all the command with
a specific command ID.
The iwl_send_add_station needs the access the command that was sent
while handling the response (regardless if the command was sent in
SYNC or ASYNC mode). So now, all the handlers receive the host
command that was sent. This implies a change in the handler signature.

iwlagn: do not use interruptible waits
Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.
This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.
Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.
This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD'
I have seen in P2P testing, but it is likely
that there are other errors caused by this.
