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. Vegard
