This also means, that DRM_FULL_MM_COMPAT is always defined,
so it is dropped, too.

This also means dropping the DRM_ODD_MM_COMPAT case.

This function is unused, and yet creates build problems: the symbol
init_mm is not exported by the latest -rc kernels and I don't believe it
ever will be. Even CONFIG_UNUSED_SYMBOLS does not provide it anymore.
If this function is needed in the future, it needs to be reinvented in
any case. So remove it.

This reverts commit 6656db10551bbb8770dd945b6d81d5138521f208.
We really just want the libdrm and ioctl bits, not all the driver
stuff.

Needed to merge in VM fault changes & pci_read_base API update.

This is an initial import of the atom bios parser with modesetting support
for r500 hw using atombios. It also includes a simple memory manager
layer that translates a radeon GEM style interface onto TTM internally.
So far this memory manager has only been used for pinned object allocation
for the DDX to test modesetting.

The kernel has removed nopage so move the old nopage codepaths into a compat vm file and switch to using the fault paths.
nopfn is on its way out in the future also, so we should switch to using fault
for that path as well soon

PCI- or high memory.
This is substantially more efficient than drm_bo_kmap,
since the mapping only lives on a single processor.
Unmapping is done use kunmap_atomic(). Flushes only a single tlb() entry.
Add a support utility int drm_bo_pfn_prot() that returns the
pfn and desired page protection for a given bo offset.
This is all intended for relocations in bound TTMS or vram.
Mapping-accessing-unmapping must be atomic, either using preempt_xx() macros
or a spinlock.

Due to commit d1187641d64f442968a3b9ea6a19de6cdd45acd4.

Kernel "cleanfile" script run.
|
|
Add interface entry cleaning a memory type without touching NO_EVICT buffers.
|
|
Someone should probably double-check my work here since this is the
first time I've touched drm_compat.[ch]

Introduce tile members for future tiled buffer support.
Allow user-space to explicitly define a fence-class.
Remove the implicit fence-class mechanism.

The vm subsystem of 2.6.21 is fully compatible with the buffer object
vm code.

Hooray!! it sort of works with a fixed AGP area as faked VRAM.

Implement a memcpy fallback for copying between buffers.

and clean up some function names.

Remove ttm objects.
Make vm aware of PCI memory type buffer objects.
(Only works for pre 2.6.16 kernels for now).

Honour the ttm backend cant-use-aperture flag.

TTM pages were not cleared when allocated and handed to user space.
Sensitive information may leak.
