Make struct boot_params a real structure, and remove obsolete fields Make struct boot_params a real structure, and remove the handling of some obsolete fields, in particular hd*_info, which was only used by the ST-506 driver, and likely to be wrong for that driver on any modern BIOS.

update boot spec to 2.07 Updates for version 2.07 of the boot protocol. This includes: load_flags.KEEP_SEGMENTS- flag to request/inhibit segment reloads hardware_subarch - what subarchitecture we're booting under hardware_subarch_data - per-architecture data The intention of these changes is to make booting a paravirtualized kernel work via the normal Linux boot protocol.

x86: EFI runtime service support This patch adds basic runtime services support for EFI x86_64 system. The main file of the patch is the addition of efi_64.c for x86_64. This file is modeled after the EFI IA32 avatar. EFI runtime services initialization are implemented in efi_64.c. Some x86_64 specifics are worth noting here. On x86_64, parameters passed to EFI firmware services need to follow the EFI calling convention. For this purpose, a set of functions named efi_call<x> (<x> is the number of parameters) are implemented. EFI function calls are wrapped before calling the firmware service. The duplicated code between efi_32.c and efi_64.c is placed in efi.c to remove them from efi_32.c.
