Hi!
Plus I guess it would be nice to add CPU HOTPLUG into MAINTAINERS
file:
There is a list of maintainers in the Documentation/cpu-hotplug.txt,
which includes maintainers for different platforms as well.
It's a good idea to add that info to the MAINTAINERS file as well.

Hi!
Venki sent me an initial patch, but it has issues with the notify
ordering. Find below my cache the broadcast flags version for testing.
Hmmpf, the flag is still cleared when the cpu goes offline. Need to take
a closer look.
I finally tracked it down. There were several ways

Hi!
What was the last known to work version ?
I'm afraid I only turned on HIGH_RES_TIMERS in 2.6.23-rc1
timeframe... so I'm not sure if it ever worked for me.
I can confirm it is working in 2.6.23-rc5 with highres disabled, and
broken with highres enabled. NOHZ turns waits for
