The patch titled
     Subject: mm-per-thread-vma-caching-fix-3
has been removed from the -mm tree.  Its filename was
     mm-per-thread-vma-caching-fix-3.patch

This patch was dropped because it was folded into mm-per-thread-vma-caching.patch

------------------------------------------------------
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Subject: mm-per-thread-vma-caching-fix-3

Attempt to untangle header files.

Prior to this patch:

mm.h does not require sched.h
sched.h does not require mm.h
sched.h requires vmacache.h
vmacache.h requires mm.h

After this patch:

mm.h still does not require sched.h
sched.h still does not require mm.h
sched.h does not require vmacache.h
mm.h does not require vmacache.h
vmacache.h requires (and includes) mm.h
vmacache.h requires (and includes) sched.h

To do all this, the three "#define VMACACHE_foo" lines were moved to
sched.h.

The inclusions of sched.h and mm.h into vmacache.h are actually unrequired
because the .c files include mm.h and sched.h directly, but I put them in
there for cargo-cult reasons.

vmacache_flush() no longer needs to be implemented in cpp - make it so.
