Add support for tracking drawable information to core
...
Actually make the existing ioctls for adding and removing drawables do
something useful, and add another ioctl for the X server to update drawable
information. The only kind of drawable information tracked so far is cliprects.

Add support for secondary vertical blank interrupt to i915 driver.
...
When the vertical blank interrupt is enabled for both pipes, pipe A is
considered primary and pipe B secondary. When it's only enabled for one pipe,
it's always considered primary for backwards compatibility.

i915: Avoid mis-counting vblank interrupts when they're only enabled for pipe A.
...
It looks like 'after a while', I915REG_INT_IDENTITY_R for some reason always has
VSYNC_PIPEB_FLAG set in the interrupt handler, even though pipe B is disabled.
So we only increase dev->vbl_received if the corresponding bit is also set in
dev->vblank_pipe.

Keep hashed user tokens, with the following changes:
...
32-bit physical device addresses are mapped directly to user-tokens. No
duplicate maps are allowed, and the addresses are assumed to be outside
of the range 0x10000000 through 0x30000000. The user-token is identical
to the 32-bit physical start-address of the map.
64-bit physical device addressed are mapped to user-tokens in the range
0x10000000 to 0x30000000 with page-size increments. The user_token should
not be interpreted as an address.
Other map types, like upcoming TTM maps are mapped to user-tokens in the
range
0x10000000 to 0x30000000 with page-size increments. The user_token should
not be interpreted as an address.
This keeps compatibility with buggy drivers, while still implementing a
hashed map lookup. The SiS and via device driver major bumps are
reverted.

Add missing pci ids for new radeons (most but not all are pcie, r420,

rv380, rv410), with the exception of the rs400 igps. Hopefully they no
longer lock up with new ddx, but no guarantees... (bug #5413 )

Add all radeon pci ids known by ddx, but only r350/rv350 and below (new
...
chips may be problematic). Leave the existing entries for new chips in
though. Remove ids not known by ddx (secondary ids, non-existant,...).
Correct some entries (name/family). Make the radeon family enum look
more alike the ddx/dri versions. See #5413
