From: Guenter Roeck <linux@roeck-us.net>
3.4.106-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit bb2e226b3bef596dd56be97df655d857b4603923 upstream.
This reverts commit 3189eddbcafc ("percpu: free percpu allocation info for uniprocessor system").
The commit causes a hang with a crisv32 image. This may be an architecture problem, but at least for now the revert is necessary to be able to boot a crisv32 image.
