625c18d706 drm: delete drm_pci.h
It's empty!

After more than 20 years of OS abstraction layer for pci devices, it's
kinda gone now.

45b2fda3d8 gpu/drm: fix a few kernel-doc "/**" mark warnings
The opening comment mark "/**" is reserved for kernel-doc comments, so
it will generate warnings for comments that are not kernel-doc with
"make W=1". For example,

drivers/gpu/drm/drm_memory.c:2: warning: Cannot understand  * \file
drm_memory.c

0500c04ea1 drm: drop use of drmP.h in drm/*
The use of the drmP.h header file is deprecated.
Remove use from all files in drm/*
so people do not look there and follow a bad example.

Build tested allyesconfig,allmodconfig on x86, arm etc.
Including alpha that is as always more challenging than
the rest.

fa5386459f drm: Used DRM_LEGACY for all legacy functions
Except for nouveau, only legacy drivers need this really. And nouveau
is already marked up with DRIVER_KMS_LEGACY_CONTEXT as the special
case.

I've tried to be careful to leave everything related to modeset still
using the DRIVER_MODESET flag. Otherwise it's a direct replacement of
!DRIVER_MODESET with DRIVER_LEGACY checks. Also helps readability
since fewer negative checks overall.

ba8286fab5 drm: Move legacy buffer structures to <drm/drm_legacy.h>
A few odd cases:
- mgag200 someho had a totally unused drm_dma_handle_t. Remove it.
- i915 still uses the legacy pci dma alloc api, so grows an include.

Everything else fairly standard.

v2: Include "drm_legacy.h" in drm.ko source files for consistency.

a266162aef drm: Move dma functions into drm_legacy.h
Also drop the unneeded EXPORT_SYMBOL and sprinkle drm_legacy_ prefixes
where missing.

v2: Drop the confusing _core_ and drop extern, both suggested by
David.

e2e99a8206 drm: mark dma setup/teardown as legacy systems
And hide the checks a bit better. This was already disallowed for
modesetting drivers, so no functinal change here.

6ebc22e6d0 drivers/gpu/drm: Use kzalloc
Use kzalloc rather than the combination of kmalloc and memset.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,size,flags;
statement S;
@@

-x = kmalloc(size,flags);
+x = kzalloc(size,flags);
 if (x == NULL) S
-memset(x, 0, size);

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.
