Commit d2348fb6fdc6 ("tick: Dynamically set broadcast irq affinity")
adds one excelent feature CLOCK_EVT_FEAT_DYNIRQ to let the core set the
interrupt affinity of the broadcast interrupt to the cpu which has the
earliest expiry time. This patch adds CLOCK_EVT_FEAT_DYNIRQ flag to
avoid unnecessary wakeups and IPIs when the dw_apb_timer is used as
broadcast timer.

I am glad this flag helps. Were you able to do some measurements ?
