Subject: [ 34/36] xen/arm: missing put_cpu in xen_percpu_init
Date: Thu,  5 Sep 2013 13:28:03 -0700	[thread overview]
Message-ID: <20130905202706.272629469@linuxfoundation.org> (raw)
In-Reply-To: <20130905202702.289738686@linuxfoundation.org>

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Julien Grall <julien.grall@linaro.org>

commit 0d7febe58413884f6428143221971618fbf3a47d upstream.

When CONFIG_PREEMPT is enabled, Linux will not be able to boot and warn:
[    4.127825] ------------[ cut here ]------------
[    4.133376] WARNING: at init/main.c:699 do_one_initcall+0x150/0x158()
[    4.140738] initcall xen_init_events+0x0/0x10c returned with preemption imbalance

This is because xen_percpu_init uses get_cpu but doesn't have the corresponding
put_cpu.
