m68k: Call timer_interrupt() with interrupts disabled

2019-03-25T09:22:24Z

Some platforms execute their timer handler with the interrupt priority level set below 6. That means the handler could be interrupted by another driver and this could lead to re-entry of the timer core. Avoid this by use of local_irq_save/restore for timer interrupt dispatch. This provides mutual exclusion around the timer interrupt flag access which is needed later in this series for the clocksource conversion.

m68k/sun3: Get interrupts working again

2012-11-14T07:50:57Z

SUN3 Intregister is not for enabling individual interrupts, but to enable special interrupts. So using it for interrupt enable/disable was wrong. The clock interrupt needs some special treatment to keep ticking. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Geert Uytterhoeven

m68k/irq: Remove obsolete support for user vector interrupt fixups

It was used on Apollo only, before its conversion to genirq. Signed-off-by: Geert Uytterhoeven

m68k/sun3: Convert Sun3/3x to genirq

2011-11-08T21:35:52Z

Replace the custom irq handler that masks the irq and calls do_IRQ(), and the unmasking in the individual handlers, by handle_level_irq(). Signed-off-by: Geert Uytterhoeven Cc: Sam Creasey

m68k/irq: Rename {,__}m68k_handle_int()

2011-11-08T21:35:48Z

- Rename m68k_handle_int() to generic_handle_irq(), and drop the unneeded asmlinkage, - Rename __m68k_handle_int() to do_IRQ(). Signed-off-by: Geert Uytterhoeven

m68k/irq: Add m68k_setup_irq_controller()

2011-11-08T21:35:48Z

This is a wrapper around m68k_setup_irq_chip() that discards its dummy second parameter, to ease the future transition to genirq. Signed-off-by: Geert Uytterhoeven

m68k/irq: Rename irq_controller to irq_chip

2011-11-08T21:35:47Z

Make it more similar to the genirq version: - Remove lock (unused as we don't do SMP anyway), - Prepend methods with irq_, - Make irq_startup() return unsigned int. Signed-off-by: Geert Uytterhoeven Acked-by: Thomas Gleixner
