genirq: Fix up irq_node() for irq_data changes.

2010-10-28T09:58:39+00:00

Now that the node ID is tracked in the irq_data structure, update the
irq_node() definition accordingly. This fixes up irq_node() usage under
GENERIC_HARDIRQS_NO_DEPRECATED && SMP.

Do not include asm/irq_vectors.h in generic code - it's not available
on all architectures.

irq: initialize nr_irqs based on nr_cpu_ids

2009-01-11T18:13:38+00:00

Impact: Reduce memory usage.

This is the second half of the changes to make the irq_desc_ptrs be
variable sized based on nr_cpu_ids.  This is done by adding a new
"max_nr_irqs" macro to irq_vectors.h (and a dummy in irqnr.h) to
return a max NR_IRQS value based on NR_CPUS or nr_cpu_ids.

This necessitated moving the define of MAX_IO_APICS to a separate
file (asm/apicnum.h) so it could be included without the baggage
of the other asm/apicdef.h declarations.

sparseirq: make for_each_irq_desc() more robust

2009-01-07T22:18:08+00:00

Raja reported for_each_irq_desc() has possibility unsafeness:

if anyone write folliwing code, for_each_irq_desc() doesn't work
as intended:

(right now this code does not exist at all)

 if (safe)
   for_each_irq_desc(irq, desc) {
      ...
   }
 else
   panic();

genirq: provide irq_to_desc() to non-genirq architectures too

2009-01-05T13:53:30+00:00

Impact: build fix on non-genirq architectures

Sam Ravnborg reported this build failure on sparc32 allmodconfig,
the GPIO drivers assume the presence of irq_to_desc():

 drivers/gpio/gpiolib.c: In function `gpiolib_dbg_show':
 drivers/gpio/gpiolib.c:1146: error: implicit declaration of function 'irq_to_desc'

Add it in the !genirq case too.

irq: simplify for_each_irq_desc() usage

2008-12-26T08:48:18+00:00

Impact: cleanup

all for_each_irq_desc() usage point have !desc check.
then its check can move into for_each_irq_desc() macro.

irq: for_each_irq_desc() move to irqnr.h

2008-12-26T08:48:17+00:00

Impact: cleanup

before CONFIG_SPARSE_IRQ age, for_each_irq_desc() sat in irqnr.h and
could be called from generic code.

CONFIG_SPARSE_IRQ breaks this assumption, but SPARSE_IRQ version
for_each_irq_desc() also can move into irqnr.h easily.

Also, this patch unifies CONFIG_SPARSE_IRQ and !CONFIG_SPARSE_IRQ
for_each_irq_desc().
