v3: Break out the prstate_housekeeping_conflict() change into 2
new patches with some testing result included.
v2: Update patch 2 to correct some of the checking code and add
prstate_housekeeping_conflict() as suggested by Chen Ridong.
The first two patches are based on the two cpuset patches from the
"timers: Exclude isolated cpus from timer migration" patch series [1]
with some modifications. They add additional nohz_full housekeeping
mask check to ensure that there is at least one common housekeeping
CPU that is not domain and nohz_full isolated.
Patches 3 & 4 fix another housekeeping CPU conflict issue reported by
Chen Ridong.
The last patch is another cleanup patch to simplify the current
partition code.
