The patch titled
drm/ttm: use shmem_read_mapping_page
has been removed from the -mm tree. Its filename was
drm-ttm-use-shmem_read_mapping_page.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: drm/ttm: use shmem_read_mapping_page
From: Hugh Dickins <hughd@xxxxxxxxxx>
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().
