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!
