Original-recipient: rfc822;
There were some areas where the OCTEON interrupt handling code could
be improved:

o Octeon irq affinity was a little weird.

o MSI code was spread out into several different files/directories.

o IRQ migration on CPU hot-plug was fragil to the point of almost
  being completely broken.

This patch set aims to make things better.

David Daney (5):
  MIPS: Octeon: Move MSI code out of octeon-irq.c.
  MIPS: Octeon: Improve interrupt handling.
  MIPS: Octeon: Fix fixup_irqs for HOTPLUG_CPU
  MIPS: Octeon: Get rid of a bunch of MSI IRQ number definitions.
  MIPS: Octeon: Make MSI use handle_simple_irq().
