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.
