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.
