        sys/arch/xen/x86/xen_intr.c: revision 1.31 (patch)
        sys/arch/xen/include/xen.h (apply patch)

xen_intr.c: Use kpreempt_disable/enable around access to curcpu().

curcpu() is not otherwise guaranteed to be stable at these points.

While here, nix nonsensical membars.  This need only be synchronized
with interrupts on the same CPU.
