Subject: [PATCH] ia64: mmap: Consider pgoff when searching for free mapping
References: bsc#1012628
Patch-mainline: 6.4.7
Git-commit: 07e981137f17e5275b6fa5fd0c28b0ddb4519702
commit 07e981137f17e5275b6fa5fd0c28b0ddb4519702 upstream.
IA64 is the only architecture which does not consider the pgoff value when
searching for a possible free memory region with vm_unmapped_area().
Adding this seems to have no negative side effect on IA64, so add it now
to make IA64 consistent with all other architectures.
