parisc: Convert the final irq bits

2011-03-29T12:48:08+00:00

1) As promised in the comment, the core does not copy cpumask anymore
   when the arch code returns -EINVAL

2) Get the per cpu information from irq_data

[PARISC] Convert to new irq_chip functions

2011-02-10T16:22:14+00:00

Convert all the parisc driver interrupt handlers (dino, eisa, gsc,
iosapic and superio) as well as the cpu interrupts.  Prepare
show_interrupts for GENERIC_HARDIRQS_NO_DEPRECATED and finally selects
that Kconfig option

[PARISC] fix per-cpu flag problem in the cpu affinity checkers

2011-02-09T19:06:07+00:00

The CHECK_IRQ_PER_CPU is wrong, it should be checking
irq_to_desc(irq)->status not just irq.

parisc: convert the rest of the irq handlers to simple/percpu

2010-12-04T16:15:19+00:00

The generic conversion eliminates the spurious no_ack and no_end
routines, converts all the cascaded handlers to handle_simple_irq() and
makes iosapic use a modified handle_percpu_irq() to become the same as
the CPU irq's.  This isn't an essential change, but it eliminates the
mask/unmask overhead of handle_level_irq().

parisc: fix dino/gsc interrupts

2010-12-04T16:14:32+00:00

The essential problem we're currently having is that dino (and gsc) is a
cascaded CPU interrupt.  Under the old __do_IRQ() handler, our CPU
interrupts basically did an ack followed by an end.  In the new scheme,
we replaced them with level handlers which do a mask, an ack and then an
unmask (but no end).  Instead, with the renaming of end to eoi, we
actually want to call the percpu flow handlers, because they actually
have all the characteristics we want.

This patch does the conversion and gets my C360 booting again.

parisc: convert iosapic interrupts to proper flow handlers

2010-10-14T05:30:16+00:00

Shift the ->end call (cpu eoi) from __do_IRQ into our
unmask handler. Also nuke some redundant code.

parisc: convert cpu interrupts to proper flow handlers

2010-10-14T05:30:13+00:00

Only major change is renaming functions to match the conventions
expected by the generic irq code.
