Most of the DRM drivers appear to be missing the .compat_ioctl file
operation entry necessary for 32-bit application compatibility.
This patch uses drm_compat_ioctl for all drivers which don't have
their own, and which are using drm_ioctl for .unlocked_ioctl.
This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom
.unlocked_ioctl and will presumably need a custom .compat_ioctl as
well.

The filed object_idr of struct drm_sis_private was introduced with
commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=6de8a748881f1cd9d795454da2b6db616d5ca3d7 .
The idr_init(&dev->object_name_idr) is called instead of
idr_init(&dev_priv->object_idr) by mistake, leaving object_idr
uninitialized. Correct this.
This patch was not tested because of lack of hardware.

The current enabling of bus mastering in the drm midlayer allows a large
race condition under kexec. When a kexec'ed kernel re-enables bus mastering
for the GPU, previously setup dma blocks may cause writes to random pieces
of memory. On radeon the writeback mechanism can cause these sorts of issues.
This patch doesn't fix the problem, but it moves the bus master enable under
the individual drivers control so they can move enabling it until later in
their load cycle and close the race.
Fix for radeon kms driver will be in a follow-up patch.

In sis_driver_load(), the only use of 'ret' is as the return value
from the function, unfortunately it is never initialized, so the
function just returns garbage when it succeeds.
To fix that, remove the variable and just return 0 directly on success.

By attach a driver private struct to each open drm fd.
Because we steal the owner_list from drm_sman until things settle,
use list_move instead of list_add.
This requires to export a drm_sman function temporarily before
drm_sman will die for real completely.

Subject: [PATCH] drm: Make the per-driver file_operations struct const
The DRM layer keeps a copy of struct file_operations inside its
big driver struct... which prevents it from being consistent and static.
For consistency (and the general security objective of having such things
static), it's desirable to get this fixed.
This patch splits out the file_operations field to its own struct,
which is then "static const", and just stick a pointer to this into
the driver struct, making it more consistent with how the rest of the
kernel does this.

This abstracts the pci/platform interface out a step further,
we can go further but this is far enough for now to allow USB
to be plugged in.
The drivers now just call the init code directly for their
device type.

new simplified stack-based kmap_atomic() interface
- drivers/gpu/drm/vmwgfx/vmwgfx_drv.c: added .llseek entry due to BKL
removal cleanups.
The drm device drivers currently allow seeking on the
character device but never care about the actual
file position.
When we change the default llseek operation to be
no_llseek, calling llseek on a drm device would
return an error condition, which is an API change.
Explicitly setting noop_llseek lets us keep the
current API.

It's not used by any driver. The destructor callback is unfortunately
used by the via driver in a rather convoluted piece of code used
to reimplement something resembling broken futexes. I didn't dare
to touch this code. But at least kill the needless NULL assignemt
in the sis driver.

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].

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.
