Subject: [PATCH] Account for memmap and optionally the kernel image as holes
X-Git-Tag: v2.6.19-rc1~978
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0e0b864e069c52a7b3e4a7da56e29b03a012fd75;p=pandora-kernel.git

[PATCH] Account for memmap and optionally the kernel image as holes

The x86_64 code accounted for memmap and some portions of the the DMA zone as
holes.  This was because those areas would never be reclaimed and accounting
for them as memory affects min watermarks.  This patch will account for the
memmap as a memory hole.  Architectures may optionally use set_dma_reserve()
if they wish to account for a portion of memory in ZONE_DMA as a hole.
