Merge remote-tracking branch 'tip/sched/arm64' into for-next/core
* tip/sched/arm64: (785 commits)
Documentation: arm64: describe asymmetric 32-bit support
arm64: Remove logic to kill 32-bit tasks on 64-bit-only cores
arm64: Hook up cmdline parameter to allow mismatched 32-bit EL0
arm64: Advertise CPUs capable of running 32-bit applications in sysfs
arm64: Prevent offlining first CPU with 32-bit EL0 on mismatched system
arm64: exec: Adjust affinity for compat tasks with mismatched 32-bit EL0
arm64: Implement task_cpu_possible_mask()
sched: Introduce dl_task_check_affinity() to check proposed affinity
sched: Allow task CPU affinity to be restricted on asymmetric systems
sched: Split the guts of sched_setaffinity() into a helper function
sched: Introduce task_struct::user_cpus_ptr to track requested affinity
sched: Reject CPU affinity changes based on task_cpu_possible_mask()
cpuset: Cleanup cpuset_cpus_allowed_fallback() use in select_fallback_rq()
cpuset: Honour task_cpu_possible_mask() in guarantee_online_cpus()
cpuset: Don't use the cpu_possible_mask as a last resort for cgroup v1
sched: Introduce task_cpu_possible_mask() to limit fallback rq selection
sched: Cgroup SCHED_IDLE support
sched/topology: Skip updating masks for non-online nodes
Linux 5.14-rc6
lib: use PFN_PHYS() in devmem_is_allowed()
