Subject: [PATCH/RFC v2 1/6] Call init_workqueues before pre smp initcalls.
Date: Mon, 13 Oct 2008 23:50:08 +0200	[thread overview]
Message-ID: <20081013215130.342077797@de.ibm.com> (raw)
In-Reply-To: <20081013215007.634620563@de.ibm.com>

[-- Attachment #1: 001_workqueue_init.diff --]
[-- Type: text/plain, Size: 911 bytes --]

From: Heiko Carstens <heiko.carstens@de.ibm.com>

This allows to create workqueues from within the context of
a pre smp initcall (aka early_initcall).
