Browse source 
Fixes this powerpc build error in 2.6.22-rc6-mm1 for powerpc 64 with
CONFIG_SWAP=n :

In file included from include2/asm/tlb.h:60,
                 from /home/compudj/git/linux-2.6-lttng/arch/powerpc/mm/init_64.
c:56:

make[2]: *** [arch/powerpc/mm/init_64.o] Error 1

release_pages is declared in linux/pagemap.h, but cannot be included in
linux/swap.h because of a sparc related 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);
