[Xen-devel] [PATCH] cpu barriers moved and x86-64 cpu barriers added

[Jerone Young <jyoung5@xxxxxxxxxx>]

Apologies if this is comes in twice. I sent this earlier today but I
don't see it on the list...;-0

We actually should have wmb() be defined as "asm volatile("":::"memory")
since we are not using out of order io.

The patch attached removes all the instances and places the definitions
in libxc/xc.h as per the discussion last week between Anthony & Keir.
