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.
