Arnd Bergmann b963d12aa6 x86/mm: Include asm/numa.h for set_highmem_pages_init()
The set_highmem_pages_init() function is declared in asm/numa.h, which
must be included in the file that defines it to avoid a W=1 warning:

arch/x86/mm/highmem_32.c:7:13: error: no previous prototype for 'set_highmem_pages_init' [-Werror=missing-prototypes]
