This patchset adds enhancements to the keepalive core monitoring and reporting sub-system. The first is support for idled (sleeping and frequency-stepped) CPU cores, and the second is support for applications to be notified of active as well as faulted cores. The latter is to allow core state to be relayed to external (secondary) processes, which is demonstrated by changes to the l2fed-keepalive example.
