end_user_pfn used to modify the meaning of the e820 maps. Now that all e820 operations are cleaned up, unified, tightened up, the e820 map always get updated to reality, we don't need to keep this secondary mechanism anymore.

This patch uses the /sys/firmware/memmap interface provided in the last patch on the x86 architecture when E820 is used. The patch copies the E820 memory map very early, and registers the E820 map afterwards via firmware_map_add_early().

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).

This patch brings back limiting of the E820 map when a user-defined E820 map is specified. While the behaviour of i386 (32 bit) was to limit the E820 map (and /proc/iomem), the behaviour of x86-64 (64 bit) was not to limit. That patch limits the E820 map again for both x86 architectures. Code was tested for compilation and booting on a 32 bit and 64 bit system.

Fix some problems with (and applies on top of) a previous patch: x86 boot: show pfn addresses in hex not decimal in some kernel info printks Primarily change "0x%8lx" format, which displays with a right aligned space filled hex number (spaces between the "0x" prefix and the number), into "%0#10lx" format, which zero fills instead of space fills, and which uses the printf flag '#' to request the "0x" prefix instead of hard coding it. Also replace some other "0x%lx" formats with "%#lx", making use of the '#' printf flag again.

This is a preparatory patch for the next patch in series. Moves some code from e820_setup_gap to a new function e820_search_gap. This patch is a part of a bug fix where we walk the ACPI table to calculate a gap for PCI optional devices. v1->v2: Patch on top of tip/master. Fixes a bug introduced in the last patch about the typeof "last". Also the new function e820_search_gap now returns if we found a gap in e820_map.

Add support for overlapping early memory reservations. In general, they still can't overlap, and will panic with "Overlapping early reservations" if they do overlap. But if a memory range is reserved with the new call: reserve_early_overlap_ok() rather than with the usual call: reserve_early() then subsequent early reservations are allowed to overlap. This new reserve_early_overlap_ok() call is only used in one place so far, which is the "BIOS reserved" reservation for the the EBDA region, which out of Paranoia reserves more than what the BIOS might have specified, and which thus might overlap with another legitimate early memory reservation (such as, perhaps, the EFI memmap.)

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.
