[PATCH] x86_64: Account mem_map in VM holes accounting
The VM needs to know about lost memory in zones to accurately balance dirty pages. This patch accounts mem_map in there too, which fixes a constant errror of a few percent. Also some other misc mappings and the kernel text itself are accounted too. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
