f4d2781731 fix radeon setparam on 32/64 systems, harder.
Commit 9b01bd5b28 introduced a
compat_ioctl handler for RADEON_SETPARAM, the sole purpose of which was
to handle the fact that on i386, alignof(uint64_t)==4.

Unfortunately, this handler was installed for _all_ 64-bit
architectures, instead of only x86_64 and ia64.  And thus it breaks
32-bit compatibility on every other arch, where 64-bit integers are
aligned to 8 bytes in 32-bit mode just the same as in 64-bit mode.

Arnd has a cunning plan to use 'compat_u64' with appropriate alignment
attributes according to the 32-bit ABI, but for now let's just make the
compat_radeon_cp_setparam routine entirely disappear on 64-bit machines
whose 32-bit compat support isn't for i386.  It would be a no-op with
compat_u64 anyway.

dc7a93190c drm/i915: Add support for the G33, Q33, and Q35 chipsets.
These require that the status page be referenced by a pointer in GTT, rather
than phsyical memory.  So, we have the X Server allocate that memory and tell
us the address, instead.

453ff94ca5 radeon: Don't mess up page flipping when a file descriptor is closed.
There can still be other contexts that may use page flipping later on, so do
just unilaterally 'clean it up', which could lead to the wrong page being
displayed, e.g. when running 3D apps with a GLX compositing manager such as
compiz using page flipping.

f2b04cd219 drm/radeon: upgrade to 1.27 - make PCI GART more flexible
radeon: make PCI GART aperture size variable, but making table size variable
    This is precursor to getting a TTM backend for this stuff, and also
    allows the PCI table to be allocated at fb 0
radeon: add support for reverse engineered xpress200m

    The IGPGART setup code was traced using mmio-trace on fglrx by myself
    and Phillip Ezolt <phillipezolt@gmail.com> on dri-devel.

    This code doesn't let the 3D driver work properly as the card has no
    vertex shader support.

    Thanks to Matthew Garrett + Ubuntu for providing me some hardware to do this
    work on.

040ac32048 drm: fix driver deadlock with AIGLX and reclaim_buffers_locked
Bugzilla Bug #9457

Add refcounting of user waiters to the DRM hardware lock, so that we can use
DRM_LOCK_CONT flag more conservatively.

Also add a kernel waiter refcount that if nonzero transfers the lock for the
kernel context when it is released. This is useful when waiting for idle and can be used for very simple fence object driver implementations for the new memory manager

80b2c386f3 drm/radeon: Fix u32 overflows when determining AGP base address in card space.
The overflows could lead to the AGP aperture overlapping the framebuffer are    in the card's address space when the latter is located at the very end of th    32 bit address space, which would result in a freeze on X server startup,
probably because the card read commands from the framebuffer instead of from    AGP.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).
