[merged] drm-remove-unnecessary-fault-wrappers.patch removed from -mm tree

[akpm]

The patch titled
     Subject: drm: remove unnecessary fault wrappers
has been removed from the -mm tree.  Its filename was
     drm-remove-unnecessary-fault-wrappers.patch

This patch was dropped because it was merged into mainline or a subsystem tree

From: Ross Zwisler <ross.zwisler@linux.intel.com>
Subject: drm: remove unnecessary fault wrappers

The fault wrappers drm_vm_fault(), drm_vm_shm_fault(), drm_vm_dma_fault()
and drm_vm_sg_fault() used to provide extra logic beyond what was in the
"drm_do_*" versions of these functions, but as of this commit:

commit ca0b07d9a969 ("drm: convert drm from nopage to fault.")

They are just unnecessary wrappers that do nothing.  Remove them, and
rename the the drm_do_* fault handlers to remove the "do_" since they no
longer have corresponding wrappers.
