[PATCH for v4.2 0/3] membarrier system call

[Mathieu Desnoyers <mathieu.desnoyers@efficios.com>]

Hi,

At this point, all we're awaiting for is formal Acked-by by affected
maintainers.

Andrew, should you eventually pick it up into your tree ? Or perhaps it should
go through Paul McKenney's tree, given that it uses synchronize_sched() ?

The only change since last post is a layout change in the patch changelog, so
I'm not even bumping the patch version (kept at v18).

Thanks,

Mathieu
