It is based on tip:sched/core. I tried to rearrange a bit the naming. We are probably not yet done with that but I guess we can fix it along with the rest. Please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git full-dynticks-for-mingo Changes on these commits since they were part of 3.9-rc1-nohz1: * Force a timekeeping CPU over the full dynticks range * Rename CONFIG_NO_HZ_FULL to CONFIG_NO_HZ_EXTENDED * Following *_nohz_extended_* APIs renames * Handle CPU hotplug for timekeeping * Rename full_nohz= kernel parameter to nohz_extended= * Improve some error handling * Improve some documentation (comments, Kconfig, ...) Many of these changes may have been suggested by several reviewers. Sorry for the missing credits, I lost a bit track...
