32ef0f59a8 Fail in DRM(agp_acquire) if the AGP aperture can't be used, such that the X 
server falls back to PCI GART or disables the DRI gracefully

3669639b21 Restore __HAVE_KERNEL_CTX_SWITCH, required for the sparc drm module in the 
kernel tree. Added comments to that effect.

1654bc5752 DA: fix for bug 484 in Bugzilla, originally from me, reworked by David 
Dawes to avoid backword incompatibilities...

39e1c534c0 Don't need to include linux/wrapper.h - we only use Set/ClearPageReserved 
from linux/mm.h now and wrapper.h has been removed in 2.5.69 and later.

fdf320a1b8 Move the linux AGP includes into drm_agp.h and only define the AGP data 
structures if AGP support is enabled in the kernel (__REALLY_HAVE_AGP).
    This fixes the compile errors on kernels without AGP support.

6611a5fb7f Split declarations/definitions in drm_scatter.h into drm_sg.h/drm_sg_tmp.h 
respectively. Splited the work out of the ioctls and renamed (with the
    _ioctl prefix). Added some more documentation. Did the same for
    drm_sgpsupport.h.

c584292e30 Put back __HAVE_KERNEL_CTX_SWITCH for David Miller's sparc drm driver 
(which doesn't live in our cvs).

Eric Anholt
766a1da2e5 Remove the map argument from DRM_*MEMORYBARRIER. Not all of the uses of 
DRM_*MEMORYBARRIER we had were related to an MMIO space. This means
    arch-specific code on the BSDs, unfortunately. Also add
    DRM_MEMORYBARRIER() and change the DRM_READMEMORYBARRIER()s that used
    to be read/write barriers to it.

f2a0c5438d Ensure driver has been initialized (dev_private != NULL) before installing 
irq handler in DRM(irq_install). Modify all drivers to ensure irq
    handler is removed before cleanup and cleanup is called at takedown.
    Remove unused buffer private struct fields in i810, i830. Check for
    lock on init/cleanup in all drivers except i810/i830. The current DDX
    for i810 and i830 doesn't hold the lock on kernel init (FIXME?).

cb32dde3be Fix potential oops and memory leaks when allocations fail in 
addbufs_agp/pci. Add support for buffer private structs with PCI DMA
    buffers. Also some debug format string fixes.

16fda821eb Pass dma handle from pci_alloc_consistent to the card for status page, 
rather than using virt_to_bus() on the virtual address.

d6a82ff9c1 Remove unused dev->map_count. We always iterate the maplist with 
list_for_each() and the count is not updated or used for stats.

dbb7beb51d Rework the Linux drm kernel module build to leverage off the standard 
kernel build system. This is based on suggestions and examples from
    David Woodhouse. This approach has the advantage that the build
    requirements of a wider range of standard kernels are now supported
    transparently, but the disadvantage of some extra complexity to handle
    building against clean vendor-distributed kernel source trees. This has
    been tested with some recent Red Hat and SuSE distributions.

c2d7ff1bf9 Bring some drm module changes over from the XFree86 trunk: 
- Reset 'bound' flag for an agp entry after undbind succeeded in
    drm_agpsupport.h (Egbert Eich).
- Ignore hw_lock for drm device if lock was set by a different instance (ie
    Xserver) to prevent second server from spinning in driver release
    function (currently only relevant for i8xx drm drivers) (David Dawes).
- Use the agpgart "key" for the unique handle for bindings rather than the
    memory address (the key is guaranteed to be unique) (David Dawes).
