-Subject: [PATCH 010/454] irq_bcm2836: Send event when onlining sleeping cores
-
-In order to reduce power consumption and bus traffic, it is sensible
-for secondary cores to enter a low-power idle state when waiting to
-be started. The wfe instruction causes a core to wait until an event
-or interrupt arrives before continuing to the next instruction.
-The sev instruction sends a wakeup event to the other cores, so call
-it from bcm2836_smp_boot_secondary, the function that wakes up the
-waiting cores during booting.
-
-It is harmless to use this patch without the corresponding change
-adding wfe to the ARMv7/ARMv8-32 stubs, but if the stubs are updated
-and this patch is not applied then the other cores will sleep forever.
