Hi,
FYI, sys_membarrier has been merged upstream in Linux 4.3-rc1. Feel free
to wire up this system call on MIPS.
Thanks!

Hi Andrew,
Since I got the Acked-by from Ralf, my understanding is that he
expects that you can pick up this patch through your tree. Please let
me know if I need to do anything more. It's the same story for
sparc/sparc64.
Thanks!
Mathieu
