Subject: [PATCH RFC V9 4/19]  xen: Defer spinlock setup until boot CPU setup
Date: Sun, 02 Jun 2013 00:52:43 +0530	[thread overview]
Message-ID: <20130601192243.5966.80786.sendpatchset@codeblue> (raw)
In-Reply-To: <20130601192125.5966.35563.sendpatchset@codeblue>

xen: Defer spinlock setup until boot CPU setup

From: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

There's no need to do it at very early init, and doing it there
makes it impossible to use the jump_label machinery.
