Subject: [PATCH 0/5] RT: scheduler fixes and rt_overload enhancements
Date: Tuesday, October 9, 2007 - 10:25 am

Hi All,

The first two patches are from Mike and Steven on LKML, which the rest of my
series is dependent on.  Patch #4 is a resend from earlier.

Series Summary:

1) Send IPI on overload regardless of whether prev is an RT task
2) Set the NEEDS_RESCHED flag on reception of RESCHED_IPI
3) Fix a mistargeted IPI on overload
4) Track which CPUS are in overload for efficiency
5) Track which CPUs are eligible for rebalancing for efficiency

These have been built and boot-tested on a 4-core Intel system.

Regards,
-Greg
