sh: use printk_ratelimited instead of printk_ratelimit

2011-06-30T06:10:06+00:00

Follows the powerpc change, for much the same rationale.

sh: Convert to generic show_interrupts.

2011-03-17T08:31:51+00:00

Trivial conversion, simply encapsulate the NMI stats in the arch code.

sh: fix up cpu hotplug IRQ migration for irq_data changes.

2010-10-28T02:33:21+00:00

This fixes up the __cpu_disable() path's IRQ migration for the
irq_data changes.

sh: update show_interrupts() for irq_data chip lookup.

2010-10-27T06:43:01+00:00

Presently the irq chip is found through the irq_desc, but as this is
going away convert over to an irq_data lookup instead.

sh: Switch dynamic IRQ creation to generic irq allocator.

2010-10-26T07:05:08+00:00

Now that the genirq code provides an IRQ bitmap of its own and the
necessary API to manipulate it, there's no need to keep our own version
around anymore.

In the process we kill off some unused IRQ reservation code, with future
users now having to tie in to the genirq API as normal.

genirq: Query arch for number of early descriptors

2010-10-12T14:39:08+00:00

sparse irq sets up NR_IRQS_LEGACY irq descriptors and archs then go
ahead and allocate more.

Use the unused return value of arch_probe_nr_irqs() to let the
architecture return the number of early allocations. Fix up all users.

sh: intc: Support virtual mappings for IRQ subgroups.

2010-10-04T19:47:03+00:00

Many interrupts that share a single mask source but are on different
hardware vectors will have an associated register tied to an INTEVT that
denotes the precise cause for the interrupt exception being triggered.

This introduces the concept of IRQ subgroups in the intc core, where
a virtual IRQ map is constructed for each of the pre-defined cause bits,
and a higher level chained handler takes control of the parent INTEVT.
This enables CPUs with heavily muxed IRQ vectors (especially across
disjoint blocks) to break things out in to a series of managed chained
handlers while being able to dynamically lookup and adopt the IRQs
created for them.

This is largely an opt-in interface, requiring CPUs to manually submit
IRQs for subgroup splitting, in addition to providing identifiers in
their enum maps that can be used for lazy lookup via the radix tree.
