Ying Huang would like setup_data to be reserved, but not included in the
no save range.

Here we try to modify the e820 table to reserve that range early.
also add that in early_res in case bootloader messes up with the ramdisk.

other solution would be
1. add early_res_to_highmem...
2. early_res_to_e820...
but they could reserve another type memory wrongly, if early_res has some
resource reserved early, and not needed later, but it is not removed from
early_res in time. Like the RAMDISK (already handled).

x86 boot: pass E820 memory map entries more than 128 via linked list of setup data 2008-07-08T08:37:39+00:00 Huang, Ying ying.huang@intel.com 2008-06-11T03:33:39+00:00 8c5beb50d3ec915d15c4d38aa37282309a65f14e Because of the size limits of struct boot_params (zero page), the maximum number of E820 memory map entries can be passed to kernel is 128. As pointed by Paul Jackson, there is some machine produced by SGI with so many nodes that the number of E820 memory map entries is more than 128. To enabling Linux kernel on these system, a new setup data type named SETUP_E820_EXT is defined to pass additional memory map entries to Linux kernel. This patch is based on x86/auto-latest branch of git-x86 tree and has been tested on x86_64 and i386 platform.

x86: EFI runtime service support 2008-01-30T12:31:19+00:00 Huang, Ying ying.huang@intel.com 2008-01-30T12:31:19+00:00 5b83683f32b113d07edfb67a33ce389fc624423d 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.
