- Enable support for UEFI on x86_64 using the ovmf-x86_64-ms.bin
  firmware from qemu-ovmf-x86_64. The firmware is preloaded with
  Microsoft keys to more closely resemble firmware on real hardware

Subject: [PATCH 09/15] hvmloader: Check modules whereabouts in perform_tests
As perform_tests() is going to clear memory past 4MB, we check that the
memory can be use or we skip the tests.
