drm/ttm: request zeroed system memory pages for new TT buffer objects

Fixes an information leak to userspace, we were handing out un-zeroed pages
for any newly created TTM_PL_TT buffer.

drm/ttm: ensure ttm for new node is bound before calling move_notify()

2011-08-23T08:38:30+00:00

This was true for new TTM_PL_SYSTEM and new TTM_PL_TT cases, but wasn't
the case on TTM_PL_SYSTEM<->TTM_PL_TT moves, which causes trouble on some
paths as nouveau's move_notify() hook requires that the dma addresses be
valid at this point.

drm/ttm: unbind ttm before destroying node in accel move cleanup

2011-08-23T08:35:16+00:00

Nouveau makes the assumption that if a TTM is bound there will be a mm_node
around for it and the backwards ordering here resulted in a use-after-free
on some eviction paths.

drm/ttm: fix ttm_bo_add_ttm(user) failure path

ttm_tt_destroy kfrees passed object, so we need to nullify

Merge 3.0-rc7 into drm-core-next

2011-07-13T07:30:22+00:00

This pulls in all the drm fixes up to this point which are needed
for some -next patches to work.

drm/ttm: use shmem_read_mapping_page

2011-06-28T01:00:13+00:00

Soon tmpfs will stop supporting ->readpage and read_mapping_page(): once
"tmpfs: add shmem_read_mapping_page_gfp" has been applied, this patch can
be applied to ease the transition.

ttm_tt_swapin() and ttm_tt_swapout() use shmem_read_mapping_page() in
place of read_mapping_page(), since their swap_space has been created with
shmem_file_setup().

vmscan: change shrinker API by passing shrink_control struct

2011-05-25T15:39:26+00:00

Change each shrinker's API by consolidating the existing parameters into
shrink_control struct.  This will simplify any further features added w/o
touching each file of shrinker.
