Hello,

Patch 1 is a plain bugfix for a feature we expose in viridian, which is
kind of unrelated to the series but patch 2 in its current form depends
on it.

Patch 2 is the actual meat and changes which features get reported as
part of the x{2,}APIC assist flag.  This is an attempt to repurpose the
flags so we don't release a version of Xen with a set of flags that we
will then either remove or use to report different hardware features.

Thanks, Roger.
