Subject: [PATCH 0/3] hotplug memory remove support for PPC64
Date: Wed, 31 Oct 2007 08:48:10 -0800	[thread overview]
Message-ID: <1193849290.17412.29.camel@dyn9047017100.beaverton.ibm.com> (raw)
In-Reply-To: <20071031143423.586498c3.kamezawa.hiroyu@jp.fujitsu.com>

Hi Paul/Andrew,

Here are few minor fixes needed to get hotplug memory remove working
on ppc64. Could you please consider them for -mm ?

	[PATCH 1/3] Add remove_memory() for ppc64
	[PATCH 2/3] Enable hotplug memory remove for ppc64
	[PATCH 3/3] Add arch-specific walk_memory_remove() for ppc64

I am able to successfully add/remove memory on ppc64 with these patches.
ZONE_MOVABLE guarantees the success, if we really really want to be able
to remove memory.

Thanks to Mel and KAME for doing all the real work :) 

TODO:
	- I am running into migrate_pages() issues on reiserfs backed
files. Nothing to do with ppc64.

Thanks,
Badari
