77d4309e19 [POWERPC] ipic: ack only for edge interrupts
Only external interrupts in edge detect mode support ack operation.
Therefore, in most cases ack is not needed.  The patch makes ipic
ack only when it's needed.  This could boost over all system performance.

52964f87c6 [POWERPC] Add an optional device_node pointer to the irq_host
The majority of irq_host implementations (3 out of 4) are associated
with a device_node, and need to stash it somewhere. Rather than having
it somewhere different for each host, add an optional device_node pointer
to the irq_host structure.

b9f0f1bb2b [POWERPC] Adapt ipic driver to new host_ops interface, add set_irq_type to set IRQ sense
This converts ipic code to Benh's IRQ mods.  For the IPIC, IRQ sense values in the device tree equal those in include/linux/irq.h; that's 8 for low assertion (most internal IRQs on mpc83xx), and 2 for high-to-low change.

spinlocks added to [un]mask, ack operations; default handler and type now set in host_map; and redundant condition check eliminated.

2ef9481e66 [PATCH] powerpc: trivial: modify comments to refer to new location of files
This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

1cd8e50620 [PATCH] powerpc: moved ipic code to arch/powerpc
Moved 83xx and QUICC Engine interrupt handling code into arch/powerpc
as a precursor of getting 83xx sub-arch building in arch/powerpc.
