Commit 06824ba824b3e9f2fedb38bee79af0643198ed7f
(ARM: tlb: delay page freeing for SMP and ARMv7 CPUs) causes
the following compile error for at least omap1_defconfig:
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 this by including pagemap.h.

Shouldn't you be #including it into tlb.h instead?

Grant already mentioned this to me this evening.
This happens if you build with CONFIG_SWAP=n, and is something that the
asm-generic/tlb.h also appears to suffer from. Why no one else has
noticed this I've no idea.
Note that linux/swap.h has this comment:
/* only sparc can not include linux/pagemap.h in this file
* so leave page_cache_release and release_pages undeclared... */
#define free_page_and_swap_cache(page) \
page_cache_release(page)
#define free_pages_and_swap_cache(pages, nr) \
release_pages((pages), (nr), 0);
which is rather annoying, because it makes the build error dependent on
the configuration.
So, we should add linux/pagemap.h to both asm-generic/tlb.h and the ARM
tlb.h as they both should suffer the same problem.
Note that arch/x86/mm/init.c and arch/x86/mm/pgtable.c both include
asm/tlb.h without linux/pagemap.h, and use the generic version. I bet
no one's tried building x86 with CONFIG_SWAP=n yet...

Hmm, pagemap.h actually seems to be there in tlb.h,
but in #ifndef CONFIG_MMU.

For me building arch/arm/mm/mmu.o fails, too. So Tony's patch doesn't
help.
Adding the #include to arch/arm/include/asm/tlb.h works fine though.

I did, and it doesn't fail.
include/asm-generic/tlb.h includes <asm/pgalloc.h> which for x86
includes <linux/pagemap.h>

Maybe then we should add linux/pagemap.h to our asm/pgalloc.h.

Looks like it's in arch/x86/mm/init_[32|64].c and pgtable[32|64].c
though. So maybe we just need to patch either ARM tlb.h. Or patch
the necessary .c files to include pagemap.h.

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.
