 Scheduler changes for v6.2:
 
  - Implement persistent user-requested affinity: introduce affinity_context::user_mask
    and unconditionally preserve the user-requested CPU affinity masks, for long-lived
    tasks to better interact with cpusets & CPU hotplug events over longer timespans,
    without destroying the original affinity intent if the underlying topology changes.
 
  - Uclamp updates: fix relationship between uclamp and fits_capacity()
 
  - PSI fixes
 
  - Misc fixes & updates.
