[PATCH 3/4] tickless idle cpus: sysctl support
From: Srivatsa Vaddagiri <hidden>
Date: 2006-04-07 06:34:23
During initial phase, it is useful to have sysctl control to turn on/off tickless idle CPU feature at run time. Patch below, against 2.6.17-rc1-mm1, provides that support for all architectures.
