++ This option adds the workaround for ARM Cortex-A510 erratum 2457168.
++
++ The AMU counter AMEVCNTR01 (constant counter) should increment at the same rate
++ as the system counter. On affected Cortex-A510 cores AMEVCNTR01 increments
++ incorrectly giving a significantly higher output value.
++
++ Work around this problem by returning 0 when reading the affected counter in
++ key locations that results in disabling all users of this counter. This effect
++ is the same to firmware disabling affected counters.

++ * cgroup_attach_lock - Lock for ->attach()
++ * @lock_threadgroup: whether to down_write cgroup_threadgroup_rwsem
++ *
++ * cgroup migration sometimes needs to stabilize threadgroups against forks and
++ * exits by write-locking cgroup_threadgroup_rwsem. However, some ->attach()
++ * implementations (e.g. cpuset), also need to disable CPU hotplug.
++ * Unfortunately, letting ->attach() operations acquire cpus_read_lock() can
++ * lead to deadlocks.
++ *
++ * Bringing up a CPU may involve creating and destroying tasks which requires
++ * read-locking threadgroup_rwsem, so threadgroup_rwsem nests inside
++ * cpus_read_lock(). If we call an ->attach() which acquires the cpus lock while
++ * write-locking threadgroup_rwsem, the locking order is reversed and we end up
++ * waiting for an on-going CPU hotplug operation which in turn is waiting for
++ * the threadgroup_rwsem to be released to create new tasks. For more details:
++ *
++ * http://lkml.kernel.org/r/20220711174629.uehfmqegcwn2lqzu@wubuntu
++ *
++ * Resolve the situation by always acquiring cpus_read_lock() before optionally
++ * write-locking cgroup_threadgroup_rwsem. This allows ->attach() to assume that
++ * CPU hotplug is disabled on entry.
