[patch 00/14] powerpc: Final irq bits for .39

[patch 00/14] powerpc: Final irq bits for .39

[Thomas Gleixner]

Ben,

the following series cleans up the remaining odds and ends of the
powerpc irq code. It further contains a coccinelle scripted conversion of
the irq functions to the new naming convention irq_*.

The last patch which makes power switch to the generic
show_interrupts() code selects GENERIC_IRQ_SHOW_LEVEL which has not
yet hit Linus tree, but should tonight.

Thanks,

	tglx

[patch 01/14] powerpc: Use proper accessors for IRQ_* flags

[Thomas Gleixner]

Use the proper accessors instead of open access to irq_desc.
Converted with coccinelle.

[patch 02/14] powerpc: media5200: Remove pointless set_irq_type()

[Thomas Gleixner]

The irq chip has no irq_set_type() callback. So calling the call is
pointless. Set IRQ_LEVEL via the proper accessor.

No need for a redundant sparse irq lookup. irqdata provides the same

[patch 04/14] powerpc: cell: Fix the irq_desc access

[Thomas Gleixner]

The core irq_set_type() function updates the flow type when the chip
callback returns 0. It also updates irq_data, so this can be used in
irq_ack() to check for the level bit. That avoids a redundant sparse
irq lookup.

[patch 05/14] powerpc: cpm2_pic: Cleanup flow type handling

[Thomas Gleixner]

The core irq_set_type() function updates the flow type when the chip
callback returns 0. So setting the type is bogus.

The new core code allows to update the type in irq_data and return
IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for
setting the IRQ_LEVEL flag.

Use the proper accessors for setting the irq handlers.
