remains. Xen is planning to phase out support for PV upstream since it is harder to maintain and has more overhead. Modern x86 CPUs include virtualization extensions that support HVM guests instead of PV guests. In addition, the PV code was i386 only and not as well maintained recently as the HVM code. - Remove the i386-only NATIVE option that was used to disable certain components for PV kernels. These components are now standard as they are on amd64. - Remove !XENHVM bits from PV drivers. - Remove various shims required for XEN (e.g. PT_UPDATES_FLUSH, LOAD_CR3, etc.) - Remove duplicate copy of <xen/features.h>. - Remove unused, i386-only xenstored.h.
