The patch titled Subject: mm: remove CONFIG_HAVE_MEMBLOCK has been added to the -mm tree. Its filename is mm-remove-config_have_memblock.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-remove-config_have_memblock.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-remove-config_have_memblock.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/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Mike Rapoport <rppt@xxxxxxxxxxxxxxxxxx> Subject: mm: remove CONFIG_HAVE_MEMBLOCK All architecures use memblock for early memory management. There is no need for the CONFIG_HAVE_MEMBLOCK configuration option.
