This patch fixes arch_local_page_offset(pfn,nid) in arm.
This new one (added by unify_pfn_to_page patches) is obviously buggy.
This macro calculate page offset in a node.
Note: about LOCAL_MAP_NR()
comment in arm's sub-archs says...
/*
* Given a kaddr, LOCAL_MAP_NR finds the owning node of the memory
* and returns the index corresponding to the appropriate page in the
* node's mem_map.
*/
but LOCAL_MAP_NR() is designed to be able to take both paddr and kaddr.
In this case, paddr is better.
