The patch titled
drivers: leave vm_flags alone
has been added to the -mm tree. Its filename is
drivers-leave-vm_flags-alone.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: Nick Piggin <npiggin@xxxxxxx>
Get rid of some vm_flags twiddling from driver code. The net result of this +
the last 4 patches is that all converted remap_vmalloc_range memory can
support get_user_pages - do we want that? Can't hurt, can it?
