Subject: [PATCH -v2.1] x86: Add a Kconfig shortcut for kvm guest kernel

This is pretty useful for the case where people want to boot the
resulting kernel in qemu/kvm or lkvm. Instead of going and searching for
each required option through the Kconfig maze, this single option should
simply enable everything required/good to have to boot the resulting
kernel in the guest.

Patch has been adapted from a version in the external lkvm tree.
