mm/vmacache: inline vmacache_valid_mm()
This function incurs in very hot paths and merely does a few loads for validity check. Lets inline it, such that we can save the function call overhead. (akpm: this is cosmetic - the compiler already inlines vmacache_valid_mm()) Signed-off-by: Davidlohr Bueso <dbueso@suse.de> Cc: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
