Subject: [PATCH RFC V11 4/18]  xen: Defer spinlock setup until boot CPU setup
Date: Mon, 22 Jul 2013 11:47:31 +0530	[thread overview]
Message-ID: <20130722061731.24737.61222.sendpatchset@codeblue> (raw)
In-Reply-To: <20130722061631.24737.75508.sendpatchset@codeblue>

xen: Defer spinlock setup until boot CPU setup

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.
