allyes builds fail on x86 32-bit:

mm/mmzone.c:101:5: error: redefinition of ‘page_cpupid_xchg_last’

The reason is the mismatch in definitions:

mm.h:

#ifdef LAST_CPUPID_NOT_IN_PAGE_FLAGS

mmzone.c:

#if defined(CONFIG_NUMA_BALANCING) && !defined(LAST_CPUPID_IN_PAGE_FLAGS)

Note the missing 'NOT_' in the latter line. I've changed it to:

#if defined(CONFIG_NUMA_BALANCING) && defined(LAST_CPUPID_NOT_IN_PAGE_FLAGS)

Thanks,

Ingo
