This one has me puzzled. I *think* we should be using
info.align_mask = do_colour_align ? (PAGE_MASK & SHMLBA) : 0;
info.align_offset = (pgoff << PAGE_SHIFT) & (SHMLBA-1);
or similar. It needs more work.

I'll drop
mm-use-vm_unmapped_area-on-sparc64-architecture.patch
mm-use-vm_unmapped_area-on-sparc64-architecture-fix.patch
