fix per-cpu flag problem in the cpu affinity checkers

2011-03-23T19:50:42Z

commit 9804c9eaeacfe78651052c5ddff31099f60ef78c upstream. The CHECK_IRQ_PER_CPU is wrong, it should be checking irq_to_desc(irq)->status not just irq. Signed-off-by: Thomas Gleixner Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman

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

2010-12-04T16:15:19Z

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(). Signed-off-by: James Bottomley Tested-by: Helge Deller Signed-off-by: Kyle McMartin

parisc: fix dino/gsc interrupts

2010-12-04T16:14:32Z

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. Signed-off-by: James Bottomley Signed-off-by: Kyle McMartin

parisc: convert iosapic interrupts to proper flow handlers

2010-10-14T05:30:16Z

Shift the ->end call (cpu eoi) from __do_IRQ into our unmask handler. Also nuke some redundant code. Signed-off-by: Kyle McMartin

parisc: convert cpu interrupts to proper flow handlers

2010-10-14T05:30:13Z

Only major change is renaming functions to match the conventions expected by the generic irq code. Signed-off-by: Kyle McMartin

parisc: lay groundwork for killing __do_IRQ

2010-10-14T05:30:11Z

Use proper accessors and handlers for generic irq cleanups. We just call back into __do_IRQ through desc->handler now, and remove the explicit calls. Signed-off-by: Kyle McMartin

parisc: Fixup last users of irq_chip->typename

2009-12-16T03:48:56Z

The typename member of struct irq_chip was kept for migration purposes and is obsolete since more than 2 years. Fix up the leftovers. Signed-off-by: Thomas Gleixner Signed-off-by: Kyle McMartin
