- shmem-sgp_quick-and-sgp_fault-redundant.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     shmem: SGP_QUICK and SGP_FAULT redundant
has been removed from the -mm tree.  Its filename was
     shmem-sgp_quick-and-sgp_fault-redundant.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: shmem: SGP_QUICK and SGP_FAULT redundant
From: Hugh Dickins <hugh@veritas.com>

Remove SGP_QUICK from the sgp_type enum: it was for shmem_populate and has no
users now.  Remove SGP_FAULT from the enum: SGP_CACHE does just as well (and
shmem_getpage is about to return with page always locked).
