Hello,

Patch 1 is a bugfix for AMD-Vi IVMD range type checks.

Further patches unify the IVMD/RMRR checks into a common function, and
the last patch tightens up the condition to panic when attempting to
boot on a system that has RMRR or IVMD regions over memory that Xen uses
as RAM.

Thanks, Roger.
