[PATCH] ARM: fix build failure

[Uwe Kleine-König]

Commit

	06824ba (ARM: tlb: delay page freeing for SMP and ARMv7 CPUs)

introduced a build failure for builds with CONFIG_SWAP=n:

	In file included from arch/arm/mm/init.c:27:
	arch/arm/include/asm/tlb.h: In function 'tlb_flush_mmu':
	arch/arm/include/asm/tlb.h:101: error: implicit declaration of function 'release_pages'
	arch/arm/include/asm/tlb.h: In function 'tlb_remove_page':
	arch/arm/include/asm/tlb.h:165: error: implicit declaration of function 'page_cache_release'

Fix that by #including <linux/pagemap.h> in <asm/pgalloc.h> as it's done
by x86.
