Only issue a "nobody cared" warning after 99900 spurious interrupts. This avoids the occasional spurious interrupt causing warnings, as per x86. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Some ARM platforms have the ability to program the interrupt controller to detect various interrupt edges and/or levels. For some platforms, this is critical to setup correctly, particularly those which the setting is dependent on the device. Currently, ARM drivers do (eg) the following: err = request_irq(irq, ...); set_irq_type(irq, IRQT_RISING); However, if the interrupt has previously been programmed to be level sensitive (for whatever reason) then this will cause an interrupt storm. Hence, if we combine set_irq_type() with request_irq(), we can then safely set the type prior to unmasking the interrupt. The unfortunate problem is that in order to support this, these flags need to be visible outside of the ARM architecture - drivers such as smc91x need these flags and they're cross-architecture. Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the property that the device would like. The IRQ controller code should do its best to select the most appropriate supported mode.

There's no need to have DMA initialised at the same time as interrupts. Move it to a core_initcall(). Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This is part of Thomas Gleixner's generic IRQ patch, which converts ARM to use the generic IRQ subsystem. Here, we wrap calls to desc->handler() in an inline function, desc_handle_irq(). This reduces the size of Thomas' patch since the changes become more localised. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This is part of Thomas Gleixner's generic IRQ patch, which converts ARM to use the generic IRQ subsystem. Here, we rename two of the irq_chip methods - wake becomes set_wake, and type becomes set_type. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This patch adds support for Dynamic Tick Timer for ARM. Dynamic Tick is also known as VST (Variable Scheduling Timeouts). Dynamic Tick has been in use in the OMAP tree since last October. The patch is not intrusive, and does not do anything unless CONFIG_NO_IDLE_HZ is defined. This patch has the following fixed based on comments from RMK: - Time is updated before calling interrupt handlers. - Added new interrupt flag SA_TIMER to avoid duplicate timer interrupts - Moved struct dyn_tick_timer to time.h until we at some point probably have an arch independent dyn-tick.h - Cleaned up testing for DYN_TICK_ENABLED in irq.c I've cleaned up this patch to fix some remaining issues: - Call the timer tick handler with irqs disabled, as it would be from a normal interrupt - if we have a dyn_tick, we better implement all methods. - generic timer_dyn_reprogram() call, to be called before sleeping - added command line option - "dyntick=" to allow boot-time control of this feature -- rmk Signed-off-by: Tony Lindgren Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
