-Subject: Update default_server during migrate_irqs_away
-From: Milton Miller <miltonm@bga.com>
-References: 460566 - LTC50723
-
-Currently, every time we determine which irq server to use, we check if
-default_server, which is the id of the bootcpu, is still online.  But
-default_server is a hardware cpu, not the logical cpu id needed to index
-cpu_online_map.
-
-Since the default server can only go offline during a cpu hotplug event,
-explicitly check the default server and choose the new one when we move
-irqs away from the cpu being offlined.
-
-This has the added benefit of only needing the boot_cpuid to be updated
-and not relying on the cpu being marked offline during migrate_irqs_away.
-
-Also, since xics_update_irq_servers only reads device tree information, we
-can call it before xics_init_host in xics_init_IRQ and then default_server
-will always be valid when we can reach get_irq_server via the host ops.
