Modified Files:
        src/sys/arch/xen/include: hypervisor.h xenring.h

Log Message:
Remove mb(), rmb() and wmb() from the kernel namespace.

These are introduced by external/bsd/common/include/asm/barrier.h

The purpose of barrier.h is to bridge the use of linux API calls
within code which uses them, such as drm code. The XEN api implicitly
uses these calls which are linuxisms within io/ring.h

This diff undos the damage.

The correct fix is to modify io/ring.h to not assume that all OSs that
XEN runs on has these functions, and to appropriately conditionally via
#ifdef __NetBSD__/#endif use the appropriate NetBSD functions. These
changes then need to be pushed upstream.
