a7fb8a23c1 drm: Remove __OS_HAS_AGP
We already express the drm/agp depencies correctly in Kconfig, so we
can rip this remnant from the shared drm core days.

Aside: Pretty much all the #ifdefs in radeon/nouveau could be killed
if ttm would provide dummy functions. I'm not going to volunteer for
that though.

v2: Use IS_ENABLED(CONFIG_AGP) as suggested by Ville

v3: Polish from Ville's review.

c631d5f90e drm: Provide compat ioctl for addfb2.1
Frame buffer modifiers extensions provided in;

  commit e3eb3250d8
  Author: Rob Clark <robdclark@gmail.com>
  Date:   Thu Feb 5 14:41:52 2015 +0000

      drm: add support for tiled/compressed/etc modifier in addfb2

Missed the structure packing/alignment problem where 64-bit
members were added after the odd number of 32-bit ones. This
makes the compiler produce structures of different sizes under
32- and 64-bit x86 targets and makes the ioctl need explicit
compat handling.

v2: Removed the typedef. (Daniel Vetter)

1f96beec7a drm: remove redundant code form drm_ioc32.c
The compat ioctl handler ends up calling access_ok() twice: first
indirectly inside compat_alloc_user_space() and then after returning
from that function. This patch fixes issue.

v2: there were three invalid removals of access_ok() that I've fixed.
Also went through all the changes couple of times and verified that
access_ok() is only removed when the buffer is allocated with
compat_alloc_user_space(). My deepest apologies for this kind of
sloppiness!

ed8b670409 drm: convert drm_ioctl to unlocked_ioctl
drm_ioctl is called with the Big Kernel Lock held,
which shows up very high in statistics on vfs_ioctl.

Moving the lock into the drm_ioctl function itself
makes sure we blame the right subsystem and it gets
us one step closer to eliminating the locked version
of fops->ioctl.

Since drm_ioctl does not require the lock itself,
we only need to hold it while calling the specific
handler. The 32 bit conversion handlers do not
interact with any other code, so they don't need
the BKL here either and can just call drm_ioctl.

As a bonus, this cleans up all the other users
of drm_ioctl which now no longer have to find
the inode or call lock_kernel.

[airlied: squashed the non-driver bits
of the second patch in here, this provides
the flag for drivers to use to select unlocked
ioctls - but doesn't modify any drivers].

09e40d65d0 drm: Only use DRM_IOCTL_UPDATE_DRAW compat wrapper for compat X86.
Only X86 32-bit uses a different alignment for "unsigned long long"
than it's 64-bit counterpart.

Therefore this compat translation is only correct, and only needed,
when either CONFIG_X86 or CONFIG_IA64.

c0e09200dc drm: reorganise drm tree to be more future proof.
With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.

This restructures the drm along the lines of other kernel components.

It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.
