Hello,

The following series aims to fix the issues seeing during shutdown on
AMD boxes related to "Receive accept error" local APIC messages.

Fix patch aims to fix the issue, while second patch adjust fixup_irqs()
given it now has a single caller.

I think at least patch 1 should be considered for 4.20, as it fixes a
real issue on AMD boxes that prevents rebooting them.

Thanks, Roger.

  x86/irq: drop fixup_irqs() parameters
