From: Helge Deller <deller@xxxxxx> 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.
