only sparc can not include linux/pagemap.h?

[Geert Uytterhoeven]

When trying to compile a m68k kernel with CONFIG_SWAP=n (e.g. allnoconfig), I'm
bitten by:

    include/asm-generic/tlb.h: In function 'tlb_flush_mmu':
    include/asm-generic/tlb.h:76: error: implicit declaration of function 'release_pages'
    include/asm-generic/tlb.h: In function 'tlb_remove_page':
    include/asm-generic/tlb.h:105: error: implicit declaration of function 'page_cache_release'

because include/linux/swap.h defines free_page_and_swap_cache() and
free_pages_and_swap_cache() to page_cache_release() resp. release_pages()
without including <linux/pagemap.h>.

include/linux/swap.h has a comment that says:

    /* 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);

Is this comment still true?

If not, I'd like to add

    #include <linux/pagemap.h>

to the !CONFIG_SWAP section of include/linux/swap.h.

If yes, would it be acceptible/work to add

    #ifndef CONFIG_SWAP
    #include <linux/pagemap.h>
    #endif

at the top of include/asm-generic/tlb.h?

Thanks!
