staging: binder: Support concurrent 32 bit and 64 bit processes.
For 64bit systems we want to use the same binder interface for 32bit and
64bit processes. Thus the size and the layout of the structures passed
between the kernel and the userspace has to be the same for both 32 and
64bit processes.
This change replaces all the uses of void* and size_t with
binder_uintptr_t and binder_size_t. These are then typedefed to specific
sizes depending on the use of the interface, as follows:
* __u32 - on legacy 32bit only userspace
* __u64 - on mixed 32/64bit userspace where all processes use the same
interface.
This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and
hooks the compat_ioctl entry for the mixed 32/64bit Android userspace.
This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for
compatability, which if set which enables the old protocol, setting
BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems.
Please note that all 64bit kernels will use the 64bit Binder ABI.

staging: android: binder: fix binder interface for 64bit compat layer
The changes in this patch will fix the binder interface for use on 64bit
machines and stand as the base of the 64bit compat support. The changes
apply to the structures that are passed between the kernel and
userspace.
Most of the changes applied mirror the change to struct binder_version
where there is no need for a 64bit wide protocol_version(on 64bit
machines). The change inlines with the existing 32bit userspace(the
structure has the same size) and simplifies the compat layer such that
the same handler can service the BINDER_VERSION ioctl.
Other changes make use of kernel types as well as user-exportable ones
and fix format specifier issues.
The changes do not affect existing 32bit ABI.

staging: android: binder: replace types with portable ones
Since this driver is meant to be used on different types of processors
and a portable driver should specify the size a variable expects to be
this patch changes the types used throughout the binder interface.
We use "userspace" types since this header will be exported and used by
the Android filesystem.
The patch does not change in any way the functionality of the binder driver.

staging: android: binder: fix BC_FREE_BUFFER ioctl declaration
BinderDriverCommands mirror the ioctl usage. Thus the size of the
structure passed through the interface should be used to generate the
ioctl No.
The change reflects the type being passed from the user space-a pointer
to a binder_buffer. This change should not affect the existing 32bit
user space since BC_FREE_BUFFER is computed as:
#define _IOW(type,nr,size) \
((type) << _IOC_TYPESHIFT) | \
((nr) << _IOC_NRSHIFT) | \
((size) << _IOC_SIZESHIFT))
and for a 32bit compiler BC_FREE_BUFFER will have the same computed
value. This change will also ease our work in differentiating
BC_FREE_BUFFER from COMPAT_BC_FREE_BUFFER.
The change does not affect existing 32bit ABI.

staging: android: binder: fix BINDER_SET_MAX_THREADS declaration
This change will fix the BINDER_SET_MAX_THREADS ioctl to use __u32
instead of size_t for setting the max threads. Thus using the same
handler for 32 and 64bit kernels.
This value is stored internally in struct binder_proc and set to 15
on open_binder() in the libbinder API(thus no need for a 64bit size_t
on 64bit platforms).
The change does not affect existing 32bit ABI.

Revert "Staging: android: delete android drivers"
This reverts commit b0a0ccfad85b3657fe999805df65f5cfe634ab8a.
Turns out I was wrong, we want these in the tree.
Note, I've disabled the drivers from the build at the moment, so other
patches can be applied to fix some build issues due to internal api
changes since the code was removed from the tree.
