* sparseirq: use kstat_irqs_cpu on non-x86 architectures tooYinghai Lu2009-01-12
| | | | | | | so we could move kstat_irqs array to irq_desc struct. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* [ARM] Convert asm/io.h to linux/io.hRussell King2008-09-06

* [ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King2008-08-07
| | | | | | This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Eliminate useless includes of asm/mach-types.hRussell King2008-08-07
| | | | | | | | There are 43 includes of asm/mach-types.h by files that don't reference anything from that file. Remove these unnecessary includes. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Fix explicit asm(-arm)?/arch-foo referencesRussell King2008-08-02
| | | | | | | | No file should be explicitly referencing its own platform headers by specifying an absolute include path. Fix these paths to use standard <asm/arch/...> includes. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * ns9xxx: fix sparse warningUwe Kleine-König2008-04-25
| | | | | | | | | | | | | | The actual warning is arch/arm/mach-ns9xxx/irq.c:65:6: warning: symbol 'handle_prio_irq' was not declared. Should it be static? Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
| * ns9xxx: check for irq lockupsUwe Kleine-König2008-04-25
| | | | | | | | | | | | | | | | When I copy-adapted handle_level_irq I skipped note_interrupt because I considered it unimportant. If I had understand its importance I would have saved myself some ours of debugging. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
| * ns9xxx: fix handle_prio_irq to unmask irqs with lower priorityUwe Kleine-König2008-04-25
| | | | | | | | | | | | | | | | | | | | When an irq is reported all lower prio irqs are masked until the current irq is acked. So never leave handle_prio_irq without acking. desc->status & IRQ_INPROGRESS should never become true because the current irq is masked until it is acked, too.

* | ns9xxx: add support for irq priorisationUwe Kleine-König2008-03-31
|/ | | | | | | | | | | prio2irq(0) is the highest prioritized interrupt. For now there is no binary change intended. If you intend to change the priorisation, you have to assert: ∀ x ∈ {0, 1, ⋯ 31}: (irq2prio ∘ prio2irq)(x) = x Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
* ns9xxx: make use of the chip's irq priorisationUwe Kleine-König2008-03-31
| | | | | | | The irq controller automatically masks the current and all lower prioritised tasks until the current irq is acked. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
* ns9xxx: prepare for adding support for Digi ns921x processorsUwe Kleine-König2008-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | The hardware team changed some things that were taken as being common to all ns9xxx processors up to now. This patch addresses: - irqs: s/IRQ_/IRQ_NS9360_/ - system module registers: some registers are still general, their definition lives now in include/asm-arm/arch-ns9xxx/regs-sys-common.h. The ns9360 specific ones are in .../regs-sys-ns9360.h As a result ns9360_systemclock cannot be static inline any more as its definition needs regs-sys-ns9360.h. This becomes a real problem when adding support for ns9215 as this will need regs-sys-ns9215.h and including both files will not work. For the same reason ns9360_reset() is now non-inline and gpio functions live in their own file. - register mapping: s/ns9xxx_map_io/ns9360_map_io/ - timer registers: move time.c to time-ns9360.c; s/ns9xxx_timer/ns9360_timer/ Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
* [ARM] 4595/1: ns9xxx: define registers as void __iomem * instead of volatile u32Uwe Kleine-König2007-10-12

* [ARM] 4545/1: ns9xxx: simplify irq ack'ingUwe Kleine-König2007-10-12
| | | | | | | | | | Now the drivers are responsible to clear the irq in the respective device, which seems to be the normal thing to do. So the ack'ing of the timer irq moved to time.c.
