From: Vijay Kumar Date: Wed, 19 Apr 2017 21:59:24 +0000 (-0600) Subject: arch, mm: convert all architectures to use 5level-fixup.h X-Git-Tag: v4.1.12-102.0.20170530_1700~12 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=d8ea0c33ad00afe2266f7d4e08d102f86597048c;p=users%2Fjedix%2Flinux-maple.git arch, mm: convert all architectures to use 5level-fixup.h If an architecture uses 4level-fixup.h we don't need to do anything as it includes 5level-fixup.h. If an architecture uses pgtable-nop*d.h, define __ARCH_USE_5LEVEL_HACK before inclusion of the header. It makes asm-generic code to use 5level-fixup.h. If an architecture has 4-level paging or folds levels on its own, include 5level-fixup.h directly. Signed-off-by: Kirill A.
