Subject: mm/slub.c warnings

Hi,

I get these warnings when compiling mm/slub.c in linux-2.6.git:

mm/slub.c: In function 'slab_alloc':
mm/slub.c:1637: warning: assignment makes pointer from integer without a cast
mm/slub.c:1637: warning: assignment makes pointer from integer without a cast
mm/slub.c: In function 'slab_free':
mm/slub.c:1796: warning: assignment makes pointer from integer without a cast
mm/slub.c:1796: warning: assignment makes pointer from integer without a cast

The actual lines are calls to cmpxchg_local(). This is probably
because I'm compiling with M386. I'm guessing the source of the
warnings is in include/asm-x86/cmpxchg_32.h, lines 283 and 286. Config
attached.
