This affects the U3 MSI code as well as the PASEMI MSI code. We keep some of the MPIC routines as helpers, and also the U3 best-guess reservation logic. The rest is replaced by the generic code. And a few printk format changes due to hwirq type change. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
