Note that boot parameters suck for pretty much any purpose but quirks -
please also add a (default off!) Kconfig option to easily enable
nohz_extended for all CPUs.
That way I will be able to test it automatically via randconfig and such.
My next question/request after that would be: could we make sure that
enabling this option does not break any applications or kernel
functionality, ASAP? Once that is offered, it becomes pushable to v3.10 I
think.
Meanwhile I have pulled your tree into tip:sched/nohz to stage and test
it, in the hope that it becomes mergable quickly! :-)
Thanks,
Ingo
