This is required for the VIA driver and at least some parts are needed
for GEM.

Add list_for_each_prev to our linux compatibility.

We need this for nouveau

MFC after:	3 days

The linux list compat code had an error which prevented list_for_each_safe()

from operating on a list with a single item.  This code is used much more by
the i915 driver with xorg-7.4.  Correct it to match the actual linux
implementation.

Update DRM to CVS snapshot as of 2005-11-28. Notable changes:

2005-11-28T23:13:57+00:00

- S3 Savage driver ported.
- Added support for ATI_fragment_shader registers for r200.
- Improved r300 support, needed for latest r300 DRI driver.
- (possibly) r300 PCIE support, needs X.Org server from CVS.
- Added support for PCI Matrox cards.
- Software fallbacks fixed for Rage 128, which used to render badly or hang.
- Some issues reported by WITNESS are fixed.
- i915 module Makefile added, as the driver may now be working, but is untested.
- Added scripts for copying and preprocessing DRM CVS for inclusion in the
  kernel.  Thanks to Daniel Stone for getting me started on that.

Update to DRM CVS as of 2005-04-12, bringing many changes:

2005-04-16T03:44:47+00:00

- Split core DRM routines back into their own module, rather than using the
  nasty templated system like before.
- Development-class R300 support in radeon driver (requires userland pieces, of
  course).
- Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the
  testbox).  Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others.
- i915 driver files, which just need to get drm_drv.c fixed to allow attachment
  to the drmsub device.  Covers i830 through i915 integrated graphics.
- savage driver files, which should require minimal changes to work.  Covers the
  Savage3D, Savage IX/MX, Savage 4, ProSavage.
- Support for color and texture tiling and HyperZ features of Radeon.

Merge from DRI CVS as of 2004-05-26. Most of the meat is new PCI IDs and a new
