Subject: Re: [PATCH] Fix hotplug cpu on x86_64
Date: Fri, 7 Oct 2005 11:50:41 +0200 [thread overview]
Message-ID: <20051007095041.GK6642@verdi.suse.de> (raw)
In-Reply-To: <4345F656.9020601@didntduck.org>
A similar patch is already queued with Linus.
I also have a followon patch to avoid the extreme memory wastage
currently caused by hotplug CPUs (e.g. with NR_CPUS==128 you currently
lose 4MB of memory just for preallocated per CPU data). But that is
something for post 2.6.14.
See ftp://ftp.firstfloor.org/pub/ak/x86_64/quilt-current/patches/*
for the current queue.
