Subject: [PATCH V13 04/14] xen: Defer spinlock setup until boot CPU setup
Date: Fri, 9 Aug 2013 19:51:52 +0530 [thread overview]
Message-ID: <1376058122-8248-5-git-send-email-raghavendra.kt@linux.vnet.ibm.com> (raw)
In-Reply-To: <1376058122-8248-1-git-send-email-raghavendra.kt@linux.vnet.ibm.com>
From: Jeremy Fitzhardinge <jeremy@goop.org>
There's no need to do it at very early init, and doing it there
makes it impossible to use the jump_label machinery.
