26dc1a3ff6 i386: Don't include lib/i386/reset.c in EFI builds 
Commit 0ba90a7f01 ("efi: Move grub_reboot() into kernel") broke
the build on i386-efi - genmoddep.awk bails out with message
  grub_reboot in reboot is duplicated in kernel
This is because both lib/i386/reset.c and kern/efi/efi.c now provide
this function.

Rather than explicitly list each i386 platform variant in
Makefile.core.def, include the contents of lib/i386/reset.c only when
GRUB_MACHINE_EFI is not set.

4e5414b2a1 i386/relocator: Align stack in grub_relocator64_efi relocator 
Unified Extensible Firmware Interface Specification, Version 2.6,
section 2.3.4, x64 Platforms, boot services, says among others:
The stack must be 16-byte aligned. So, do it. Otherwise OS may
boot only by chance as it happens right now.

b67a95ecad xen: modify page table construction 
Modify the page table construction to allow multiple virtual regions
to be mapped. This is done as preparation for removing the p2m list
from the initial kernel mapping in order to support huge pv domains.

This allows a cleaner approach for mapping the relocator page by
using this capability.

The interface to the assembler level of the relocator has to be changed
in order to be able to process multiple page table areas.

9862b24121 i386/relocator: Add grub_relocator64_efi relocator 
Add grub_relocator64_efi relocator. It will be used on EFI 64-bit platforms
when multiboot2 compatible image requests MULTIBOOT_TAG_TYPE_EFI_BS. Relocator
will set lower parts of %rax and %rbx accordingly to multiboot2 specification.
On the other hand processor mode, just before jumping into loaded image, will
be set accordingly to Unified Extensible Firmware Interface Specification,
Version 2.4 Errata B, section 2.3.4, x64 Platforms, boot services. This way
loaded image will be able to use EFI boot services without any issues.
