Subject: [PATCH 0/3 for 4.2] sys_membarrier (x86, generic)

Hi,

I am submitting the membarrier system call for the upcoming Linux 4.2
merge window. It would be nice if it could sit a few days in Andrew
Morton's tree before that.

A major addition to sys_membarrier changelog is the inclusion of the
list of users which would benefit from having this system call today.

Thanks,

Mathieu
