[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.
