The patch titled Subject: mm: define MADV_FREE for some arches has been added to the -mm tree. Its filename is mm-support-madvisemadv_free-fix.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-support-madvisemadv_free-fix.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-support-madvisemadv_free-fix.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Minchan Kim <minchan@xxxxxxxxxx> Subject: mm: define MADV_FREE for some arches Most architectures use asm-generic, but alpha, mips, parisc, xtensa need their own definitions. This patch defines MADV_FREE for them so it should fix build break for their architectures. Maybe, I should split and feed piecies to arch maintainers but included here for mmotm convenience.
