Looks like there are a few places (in arch/powerpc) that were getting
asm/prom.h via asm/lmb.h, I'll send a patch in the morning.
arch/powerpc/mm/numa.c:124: error: implicit declaration of function 'of_find_node_by_type'
arch/powerpc/platforms/ps3/os-area.c:215: error: variable 'property_rtc_diff' has initializer but incomplete type
