kib a73674620c As a workaround, for Intel CPUs, do not use CLFLUSH in
pmap_invalidate_cache_range() when self-snoop is apparently not reported
in cpu features. We get a reserved trap when clflushing APIC registers
window.

XEN in full system virtualization mode removes self-snoop from CPU
features, making this a problem.
