xtensa: Fixup irq conversion fallout and nmi_count

2011-04-19T22:32:09+00:00

Some unnamed moron fatfingered the arguments of the irq chip callbacks
to irq_chip instead of irq_data.

While at it remove the nmi_count() print in arch_show_interrupts()
which has been broken before the irq conversion already.

3 years transition phase is enough. Cleanup the last users and remove
the cruft.

xtensa: allow variant to initialize own irq chips

2009-06-22T09:36:59+00:00

There was already a PLATFORM_NR_IRQS define, which is now accompanied
by a VARIANT_NR_IRQS. To be able to initialize these interrupts,
init_IRQ now calls a variant specific hook.

Changes compared to v1:
- adapted to new CONFIG_VARIANT_IRQ_EXT
- removed definition and call of platform_init_IRQ as there already
  is a platform_init_irq defined in asm/platform.h with a weak default
  in kernel/platform.c
- renamed variant_init_IRQ to variant_init_irq

Note that I could not find the call site of platform_init_irq although
it is stated in platform.h that it is called from init_IRQ.

So could move kstat_irqs array to irq_desc struct.

(s390, m68k, sparc) are not touched yet, because they don't support genirq
