Subject: [PATCH] mm: cma: fix accounting of CMA pages placed in high memory
Date: Mon, 04 Feb 2013 11:27:05 +0100 [thread overview]
Message-ID: <1359973626-3900-1-git-send-email-m.szyprowski@samsung.com> (raw)
The total number of low memory pages is determined as
totalram_pages - totalhigh_pages, so without this patch all CMA
pageblocks placed in highmem were accounted to low memory.
