[Xen-devel] tboot support broken by c/s 19075

["Cihula, Joseph" <joseph.cihula@xxxxxxxxx>]

The following changeset breaks Xen support for tboot (the version of tboot in 
SourceForge/bughost as well as with recent patches).  I am trying to see what 
aspect of this is causing the problem, but if perhaps someone could see 
something obvious and save me some time...

The error is:
(XEN) Early fatal page fault at e008:ffff828c80117c22 (cr2=0000000001157202, ec=
