Message-ID: <20140908220654.GO17501@suse.de> Date: Mon, 8 Sep 2014 23:06:54 +0100 From: Mel Gorman <mgorman@...e.de> To: Christoph Lameter <cl@...ux.com> Cc: Tejun Heo <tj@...nel.org>, LKML <linux-kernel@...r.kernel.org> Subject: [PATCH] percpu: Resolve ambiguities in __get_cpu_var/cpumask_var_t -fix A commit in linux-next was causing boot to fail and bisection identified the patch "percpu: Resolve ambiguities in __get_cpu_var/cpumask_var_". The commit ID is worthless as it's a linux-next commit. One of the changes in that patch looks very suspicious. Reverting the full patch fixes boot as does this fixlet.
