Sorry, yes, I did this on top of the Debian 3.2 branch and that *does* have a patch to arch/arm/mm/mmap.c that I had forgotten about (commit 7dbaa466780a "ARM: 7169/1: topdown mmap support"). I think you can just drop the changes in ARM's arch_get_unmapped_area_topdown(). Ben. -- Ben Hutchings Sturgeon's Law: Ninety percent of everything is crap.
