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. |
