Details:

After applying the patch to align the stack(*), grub2 crashed my UEFI
VM(OVMF)
while I launched grub.efi either from the shell or the boot manager.

OS: openSUSE 12.3 with kernel 3.12
QEMU version: 1.6.0
UEFI: OVMF r14871

Procedure to reproduce:
1. copy grub.efi to hda-contents/

2. Start the virtual machine
$ qemu-system-x86_64 -s -enable-kvm -bios /usr/share/qemu/ovmf-x86_64.bin \
-hda fat:hda-contents/ -monitor stdio -debugcon file:debug.log \
-global isa-debugcon.iobase=0x402

3. Use uefi shell to execute grub.efi
shell> grub.efi

When grub.efi started, it printed a few lines such as "Welcom to GRUB!" and
then the VM crashed with a KVM internal error.
