I would suggest to remove the "experimental" status from Kdump. Kdump is now in the kernel since a long time and used by Enterprise distributions. I don't think that "experimental" is true any more. Signed-off-by:

Applies on top of the previous patch: x86 boot: add code to add BIOS provided EFI memory entries to kernel Instead of always adding EFI memory map entries (if present) to the memory map after initially finding either E820 BIOS memory map entries and/or kernel command line memmap entries, -instead- only add such additional EFI memory map entries if the kernel boot option: add_efi_memmap is specified. Requiring this 'add_efi_memmap' option is backward compatible with kernels that didn't load such additional EFI memory map entries in the first place, and it doesn't override a configuration that tries to replace all E820 or EFI BIOS memory map entries with ones given entirely on the kernel command line.

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. Signed-off-by:

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. Signed-off-by:

that range is from find_e820_area, so don't try to use end_pfn to see if out of boundary...use table_top instead to avoid possible strange result while cross the boundary... also change early_printk to printk, because init_memory_mapping is after early param parsing, and console=uart8250 already working at that time.

... so can we use mem below max_low_pfn earlier. this allows us to move several functions more early instead of waiting to after paging_init. That includes moving relocate_initrd() earlier in the bootup, and kva related early setup done in initmem_init. (in followup patches) Signed-off-by:

This removes a pile of buggy open-coded implementations of savesegment and loadsegment. (They are buggy because they don't have memory barriers to prevent them from being reordered with respect to memory accesses.) Signed-off-by:
