[PATCH 4/4] powerpc: Enable lockup and hung task detectors in pseries and ppc64 defeconfigs
From: Anton Blanchard <hidden>
Date: 2011-07-06 23:13:17
As a result of changes to Kconfig files, we no longer enable the lockup and hung task detectors. Both are very light weight and provide useful information in the event of a hang, so reenable them.
