Hi Christophe, Greg
There is no "v" for this series :(
I thought about adding v1.
I made it as PATCH from RFC PATCH since functionally it should
be complete now with arch bits. Since it is v1, I remember usually
people send out without adding v1. after v1 had tags such as v2.
I will keep v2 for the next series.
But you are listing changes compared to v3, how can it be a v1 ?
Shouldn't it be a v4 ? Or in reality a v5 as you already sent a v4 here
[1].

Sorry about the confusion in numbers. Hopefully below helps for reviewing.
If there are no objections, I will keep next one as v2. Please let me know.
Revision logs:
++++++++++++++++++++++++++++++++++++++
RFC PATCH v4 -> PATCH (This series)
++++++++++++++++++++++++++++++++++++++
- Last two patches were sent out separate instead of being with series.
Sent it as part of series.
- Use DEVICE_ATTR_RW instead (greg)
- Made it as PATCH since arch specific handling completes the
functionality.
+++++++++++++++++++++++++++++++++
RFC PATCH v3 -> RFC PATCH v4
+++++++++++++++++++++++++++++++++
- Introduced computation of steal time in powerpc code.
- Derive number of CPUs to use and mark the remaining as paravirt based
on steal values.
- Provide debugfs knobs to alter how steal time values being used.
- Removed static key check for paravirt CPUs (Yury)
- Removed preempt_disable/enable while calling stopper (Prateek)
- Made select_idle_sibling and friends aware of paravirt CPUs.
- Removed 3 unused schedstat fields and introduced 2 related to paravirt
handling.
- Handled nohz_full case by enabling tick on it when there is CFS/RT on
it.
- Updated debug patch to override arch behavior for easier debugging
during development.
- Kept the method to push only current task out instead of moving all task's
on rq given the complexity of later.
+++++++++++++++++++++++++++++++++
RFC v2 -> RFC PATCH v3
+++++++++++++++++++++++++++++++++
- Renamed to paravirt_cpus_mask
- Folded the changes under CONFIG_PARAVIRT.
- Fixed the crash due work_buf corruption while using
stop_one_cpu_nowait.
- Added sysfs documentation.
- Copy most of __balance_push_cpu_stop to new one, this helps it move
the code out of CONFIG_HOTPLUG_CPU.
- Some of the code movement suggested.
+++++++++++++++++++++++++++++++++
RFC PATCH -> RFC v2
+++++++++++++++++++++++++++++++++
- Renamed to cpu_avoid_mask in place of cpu_parked_mask.
- Used a static key such that no impact to regular case.
- add sysfs file to show avoid CPUs.
- Make RT understand avoid CPUs.
- Add documentation patch
- Took care of reported compile error when NR_CPUS=1
