    The specific case I am encountering is kdump under Xen with a 64 bit
    hypervisor and 32 bit kernel/userspace. The dump created is 64 bit due to
    the hypervisor but the dump kernel is 32 bit for maximum compatibility.

    It's possibly less likely to be useful in a purely native scenario but I
    see no reason to disallow it.

  • 4b6f5d20b   [PATCH] Make most file operations structs in fs/ const ... Browse Code »

    This is a conversion to make the various file_operations structs in fs/
    const. Basically a regexp job, with a few manual fixups

    The goal is both to increase correctness (harder to accidentally write to
    shared datastructures) and reducing the false sharing of cachelines with
    things that get dirty in .data (while .rodata is nicely read only and thus
    cache clean)

  • 666bfddbe   [PATCH] kdump: Access dump file in elf format (/proc/vmcore) ... Browse Code »

    From: "Vivek Goyal"

    o Support for /proc/vmcore interface. This interface exports elf core image
    either in ELF32 or ELF64 format, depending on the format in which elf headers
    have been stored by crashed kernel.
    o Added support for CONFIG_VMCORE config option.
    o Removed the dependency on /proc/kcore.

    From: "Eric W. Biederman"

    This patch has been refactored to more closely match the prevailing style in
    the affected files. And to clearly indicate the dependency between
    /proc/kcore and proc/vmcore.c

    From: Hariprasad Nellitheertha

    This patch contains the code that provides an ELF format interface to the
    previous kernel's memory post kexec reboot.

    This patch provides the interfaces necessary to read the dump contents,
    treating it as a high memory device.
