alpha: Fixup last users of irq_chip->typename

2009-12-01T03:51:31+00:00

The typename member of struct irq_chip was kept for migration purposes
and is obsolete since more than 2 years. Fix up the leftovers.

irq: update all arches for new irq_desc

2009-01-12T23:27:13+00:00

Impact: cleanup, update to new cpumask API

Irq_desc.affinity and irq_desc.pending_mask are now cpumask_var_t's
so access to them should be using the new cpumask API.

sparseirq: use kstat_irqs_cpu on non-x86 architectures too

2009-01-12T19:01:12+00:00

so we could move kstat_irqs array to irq_desc struct.

cpumask: convert kernel/irq

2008-12-31T23:42:26+00:00

Impact: Reduce stack usage, use new cpumask API.  ALPHA mod!

Main change is that irq_default_affinity becomes a cpumask_var_t, so
treat it as a pointer (this effects alpha).

cpumask: make irq_set_affinity() take a const struct cpumask

2008-12-13T10:50:26+00:00

Impact: change existing irq_chip API

Not much point with gentle transition here: the struct irq_chip's
setaffinity method signature needs to change.

Fortunately, not widely used code, but hits a few architectures.

Note: In irq_select_affinity() I save a temporary in by mangling
irq_desc[irq].affinity directly.  Ingo, does this break anything?

genirq: Expose default irq affinity mask (take 3)

2008-06-05T13:18:30+00:00

Current IRQ affinity interface does not provide a way to set affinity
for the IRQs that will be allocated/activated in the future.
This patch creates /proc/irq/default_smp_affinity that lets users set
default affinity mask for the newly allocated IRQs. Changing the default
does not affect affinity masks for the currently active IRQs, they
have to be changed explicitly.

Updated based on Paul J's comments and added some more documentation.

[PATCH] alpha pt_regs cleanups: handle_irq()

2006-10-08T19:32:35+00:00

isa_no_iack_sc_device_interrupt() always gets get_irq_regs() as
argument; kill that argument.

All but two callers of handle_irq() pass get_irq_regs() as argument;
convert the remaining two, kill set_irq_regs() inside handle_irq().
