X-Git-Tag: omap-for-v3.11/fixes-for-merge-window~41^2^2~4^2~2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b19f93351dd68cb68a1a5b2d74e13d2ddfcfc64;p=pandora-kernel.git ARM: mm: Add support for flushing HugeTLB pages. On ARM we use the __flush_dcache_page function to flush the dcache of pages when needed; usually when the PG_dcache_clean bit is unset and we are setting a PTE. A HugeTLB page is represented as a compound page consisting of an array of pages. Thus to flush the dcache of a HugeTLB page, one must flush more than a single page. This patch modifies __flush_dcache_page such that all constituent pages of a HugeTLB page are flushed. Signed-off-by: Steve Capper Reviewed-by: Will Deacon --- Reading git-diff-tree failed
