Subject: [RFC PATCH v3 0/2] KVM: x86: Allow Qemu/KVM to use PVH entry point

Changes from v2:

 * All structures (including memory map table entries) are padded and
   aligned to an 8 byte boundary.

 * Removed the "packed" attributes and made changes to comments as
   suggested by Jan.

Changes from v1:

 * Adopted Paolo's suggestion for defining a v2 PVH ABI that includes the
   e820 map instead of using the second module entry to pass the table.

 * Cleaned things up a bit to reduce the number of xen vs non-xen special
   cases.
