Revision 755563bc79c764c90b9f44db5e4fe6c556d3440c authored by Paul Mackerras on 19 March 2015, 08:29:01 UTC, committed by Michael Ellerman on 20 March 2015, 03:51:53 UTC
Since we can now use hypervisor doorbells for host IPIs, this makes sure we clear the host IPI flag when taking a doorbell interrupt, and clears any pending doorbell IPI in pnv_smp_cpu_kill_self() (as we already do for IPIs sent via the XICS interrupt controller). Otherwise if there did happen to be a leftover pending doorbell interrupt for an offline CPU thread for any reason, it would prevent that thread from going into a power-saving mode; it would instead keep waking up because of the interrupt.
