Thread-topic: [PATCH] HVM x86_32 PAE guest support on 64-bit Xen
The patch enables x86_32 PAE unmodified guests on 64-bit Xen when the
hvm feature is present. We tested only Linux at this point, and we'll
improve the functionality as we test other guests.

The SVM needs the equivalent changes to the vmc.c to get this
functionality working, but this patch does not break the build.
