Message-ID: <20081031175203.GA7483@us.ibm.com> Date: Fri, 31 Oct 2008 10:52:03 -0700 From: Gary Hade <garyhade@...ibm.com> To: Ingo Molnar <mingo@...e.hu> Cc: Gary Hade <garyhade@...ibm.com>, linux-mm@...ck.org, Yasunori Goto <y-goto@...fujitsu.com>, Mel Gorman <mel@....ul.ie>, Chris McDermott <lcm@...ibm.com>, linux-kernel@...r.kernel.org, x86@...nel.org Subject: [PATCH] [RESEND] x86: add memory hotremove config option 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.
