[PATCH] Move the fix to align node_end_pfns to a proper location
Move the fix to align node_end_pfns to a proper location. The earlier fix made the node_remap_start_vaddr to get misaligned causing remap_numa_kva to barf again :-/ Signed-off-by: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Shai Fultheim <shai@scalex86.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
