hch originally submitted this for paravirt ops work, airlied took it
and cleaned up a lot of unused code caused by using this.

* 'drm-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (21 commits)
Fix http://bugzilla.kernel.org/show_bug.cgi?id=7606
drm: add flag for mapping PCI DMA buffers read-only.
drm: fix up irqflags in drm_lock.c
drm: i915 updates
drm: i915: fix up irqflags arg
drm: i915: Only return EBUSY after we've established we need to schedule a new swap.
drm: i915: Fix 'sequence has passed' condition in i915_vblank_swap().
drm: i915: Add SAREA fileds for determining which pipe to sync window buffer swaps to.
drm: Make handling of dev_priv->vblank_pipe more robust.
drm: DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead
drm: i915: Add ioctl for scheduling buffer swaps at vertical blanks.
drm: Core vsync: Don't clobber target sequence number when scheduling signal.
drm: Core vsync: Add flag DRM_VBLANK_NEXTONMISS.
drm: Make locked tasklet handling more robust.
drm: drm_rmdraw: Declare id and idx as signed so testing for < 0 works as intended.
drm: Change first valid DRM drawable ID to be 1 instead of 0.
drm: drawable locking + memory management fixes + copyright
drm: Add support for interrupt triggered driver callback with lock held to DRM core.
drm: Add support for tracking drawable information to core
drm: add support for secondary vertical blank interrupt to i915

Some drivers are returning OOM when it is not in response to a memory
shortage.

Add DRM_PCI_BUFFER_RO flag for mapping PCI DMA buffer read-only. An additional
flag is needed, since PCI DMA buffers do not have an associated map.

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.
Implement hashed map lookups.

This patch removes some of the old compatibility macros from the DRM,
and removes use of DRM wrappers from Linux specific code.

Make sure the callers do a pgprot_noncached() on
vma->vm_page_prot.

Semaphore to mutex conversion.
The conversion was generated via scripts, and the result was validated
automatically via a script as well.

I've been threatening this for a while, so no point hanging around.
This lindents the DRM code which was always really bad in tabbing department.
I've also fixed some misnamed files in comments and removed some trailing
whitespace.

Remove a bogus check on whether an area is memory (we need a better interface)
also change pgprot flags for powerpc
don't check on x86-64 either

I basically combined Paul's patches with additions that I had made
for PCI scatter gather.
I also tried more carefully to avoid problems with the same token
assigned multiple times while trying to use the base address in the
token if possible to gain as much backward compatibility as possible
for broken DRI clients.

The DRM needs to change the drm_pci interface for FreeBSD compatiblity,
this patch introduces the drm_dma_handle_t and uses it in the Linux code.

Added a new DRM map type _DRM_CONSISTENT for consistent PCI memory. It
uses drm_pci_alloc/free for allocating/freeing the memory.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
