| Subject: Revert "percpu: free percpu allocation info for uniprocessor system" |
| |
| From: Guenter Roeck <linux@roeck-us.net> |
| |
| 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. |
