[PATCH 0/3] x86_64 EFI runtime service support

Following sets of patches add EFI/UEFI (Unified Extensible Firmware
Interface) runtime services support to x86_64 architecture. The
patches have been tested against 2.6.23-rc2 kernel on Intel platforms
with EFI1.10 and UEFI2.0 firmware. This patch set is based on previous
x86_64 EFI boot support patch set.

Known issues:

- Virtual mode support is still retained in this patch. The fixmap is
used to map IO region used by EFI runtime service. This makes kexec
workable under EFI.

- The variable efi_enabled is used throughout across architectures if
CONFIG_EFI option is enabled. The i386 code also uses this variable.
This is something that can be revisited with code consolidation
across architectures. But, the EFI time runtime service is changed to
use function pointers, and the EFI reset_system runtime service is
changed to use reboot_type variable.

Looking forward to your comments,

Best Regards,
Huang Ying
