gpu/doc: Convert to markdown harder
gpu/doc: Add vga_switcheroo documentation
...
Just one special case (since i915 lost its ums code, yay):
- radeon: Has slots for the old ums ioctls which don't have
DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it
everywhere.
Every other kms driver just has DRM_UNLOCKED for all their ioctls, as
they should.
v2: admgpu happened, include that one too. And i915 lost its UMS
support which means we can change all the i915 ioctls too.
v3: Rebased on top of new vmwgfx DX interface extensions.
v4: Rebase on top of render-node support in exynos.

The cursor_set2 hook provides the cursor hotspot position within the
cursor image. When the hotspot position changes, we can adjust the cursor
position such that the hotspot doesn't move on the screen. This prevents
the cursor from appearing to intermittently jump around on the screen
when the position of the hotspot within the cursor image changes.

The new amdgpu driver passes a user space pointer in a 64-bit structure
member, which is the correct way to do it, but it attempts to
directly cast it to a __user pointer in the kernel, which causes
a warning in three places:
drm/amd/amdgpu/amdgpu_cs.c: In function 'amdgpu_cs_parser_init':
drm/amd/amdgpu/amdgpu_cs.c:180:21: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
chunk_array_user = (uint64_t __user *)(cs->in.chunks);
This changes all three to add an intermediate cast to 'unsigned long'
as other drivers do. This avoids the warning and works correctly on
both 32-bit and 64-bit architectures.
