Linux Operating System Source Code: IBM Patches

 
Use cpu_possible per-cpu data area : RCU, timers, tasklet, bh_accounting
Description:
The static per-CPU data area allows saving of space by allocating for only cpu_possible() cpus and eventually supporting NUMA-aware allocation. So per-CPU data for RCU, timer, tasklet, bh accounting etc. is changed to use static per-CPU data area. Also added support for CPU notifiers as required by late initialization of per-cpu data areas and needed for future CPU hotplug support.
