Pull scheduler fixes from Ingo Molnar:
- Fix LLC mis-scheduling bugs (Tim Chen, Lu Wang)
- Fix cache-grouping related scheduling statistics UAF bugs (Tim Chen)
- Skip kernel threads for cache aware scheduling to rubustify the code
(Chen Yu)
- Refresh LLC capacity across CPU hotplug, to fix capacity
underestimation bug (Davi Chaves Azevedo)
- Account PSI IRQ time to the execution context, not the scheduling
context, to fix proxy scheduling accounting bug (Zhan Xusheng)
