Hi, David/Ralf, I tried to regenerate a patch for this, and after git clone git://git.linux-mips.org/pub/scm/linux I found out that there is arch/mips/mm/mmap.c, but could not find out who/how this file was merged. I doubt that I may "git clone" a wrong repo that is no longer valid.

I post a simple testing program at http://www.linux-mips.org/archives/linux-mips/2011-05/msg00252.html And it was also tested in a real application using mmap heavily and need this patch to avoid failure. It is my bad to take your suggestion literally. How about arch_get_unmapped_area_common()?

I think it needs a better name than that. I will try to test it on my Octeon system sometime. David Daney
