Subject: [PATCH] mm: fix typo in mm.h when NODE_NOT_IN_PAGE_FLAGS

NODE_NOT_IN_PAGE_FLAGS is defined in mm.h when the node information
is not stored in the page flags bitmap.

Unfortunately, there's a typo in one of the checks for it. This patch
fixes it (s/NODE_NOT_IN_PAGEFLAGS/NODE_NOT_IN_PAGE_FLAGS/). Since this
has been around for ages, I doubt it's been causing any serious problems.

Patch taken against 2.6.36-rc3.
