irq_chip.end got obsolete with the removal of __do_IRQ().
irq-mb93093.c even lacks an implementation, but nobody noticed that
it's broken since commit 88d6e1 in 2006.

These functions take irq_data as an argument and avoid a redundant
lookup in the sparse irq case.

Make use of the new features in genirq:
1) Set the chip flag IRCHIP_EOI_IF_HANDLED, which ensures in the
core code that irq_eoi() is only called when the interrupt was
handled. That removes the extra status check in the callback.
2) Use the preflow handler, which is called from the fasteoi core code
before the device handler. That avoids another status check and the
open coded handler redirection.

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

The core irq_set_type() function updates the flow type when the chip
callback returns 0. So setting the type is bogus. The core also
updates IRQ_LEVEL.
Use irq_data to get the level type information in the chip functions.

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.
Retrieve the IRQ_LEVEL information from irq_data which avoids a
redundant sparse irq lookup as well.

The core code provides the same functionality when the
IRQCHIP_EOI_IF_HANDLED flag is set for the irq chip.

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.

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

Make use of the IRQCHIP_ONOFFLINE_ENABLED flag and remove the
wrappers. Use irqd_irq_disabled() instead of desc->status, which will
go away.

This includes conversion to new style irq_chip functions, and
correctly enabling/disabling per-CPU interrupts.
The hardware interrupt bit to irq number mapping is now done with a
flexible map, instead of by bit twiddling the irq number.
[ tglx: Adjusted to new irq_cpu_on/offline callbacks and
__irq_set_affinity_lock ]
