    I am resending this patch (originally posted by Badari Pulavarty)
    since the "mm: cleanup to make remove_memory() arch-neutral" patch
    on which it depends is now in Linus' 2.6.git tree (commit
    71088785c6bc68fddb450063d57b1bd1c78e0ea1) and 2.6.28-rc2.

    Thanks,
    Gary

    Add memory hotremove config option to x86

    Memory hotremove functionality can currently be configured into
    the ia64, powerpc, and s390 kernels. This patch makes it possible
    to configure the memory hotremove functionality into the x86
    kernel as well.
