Subject: [PATCH] x86: set_highmem_pages_init() cleanup
From: Pekka Enberg <penberg@...helsinki.fi>
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 CONFIG_HIGHMEM is enabled so we can't put the empty static inline
function there.
