Subject: [PATCH 3/4] tickless idle cpus: sysctl support

From: Srivatsa Vaddagiri <[email-masked]>
Date: Fri, 7 Apr 2006 12:02:08 +0530

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.
