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'

as linux/swap.h doesn't include linux/pagemap.h but actually needs it
(see comments in linux/swap.h as to why this is.)

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

ARM: pgtable: switch order of Linux vs hardware page tables 2010-12-22T11:05:32+00:00 Russell King rmk+kernel@arm.linux.org.uk 2010-11-16T00:16:01+00:00 d30e45eeabefadc6039d7f876a59e5f5f6cb11c6 This switches the ordering of the Linux vs hardware page tables in each page, thereby eliminating some of the arithmetic in the page table walks. As we now place the Linux page table at the beginning of the page, we can deal with the offset in the pgt by simply masking it away, along with the other control bits. This also makes the arithmetic all be positive, rather than a mixture. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
