x86: set_highmem_pages_init() cleanup
Impact: cleanup This patch moves set_highmem_pages_init() to arch/x86/mm/highmem_32.c. The declaration of the function is kept in asm/numa_32.h because asm/highmem.h is included only if CONFIG_HIGHMEM is enabled so we can't put the empty static inline function there.
