2019-03-25m68k: Call timer_interrupt() with interrupts disabledFinn Thain
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.

2011-11-08m68k/q40: Convert Q40/Q60 to genirqGeert Uytterhoeven
q40_irq_handler() must be kept to translate ISA IRQs to the range 1-15. q40_probe_irq_o{ff,n}() become unused. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Richard Zidlicky <rz@linux-m68k.org>
2011-11-08m68k/irq: Rename {,__}m68k_handle_int()Geert Uytterhoeven
- 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 <geert@linux-m68k.org>
2011-11-08m68k/irq: Add m68k_setup_irq_controller()Geert Uytterhoeven
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 <geert@linux-m68k.org>

2011-11-08m68k/irq: Rename irq_controller to irq_chipGeert Uytterhoeven
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 <geert@linux-m68k.org> Acked-by: Thomas Gleixner <tglx@linutronix.de>

2006-10-09IRQ: Use the new typedef for interrupt handler function pointersDavid Howells
Use the new typedef for interrupt handler function pointers rather than actually spelling out the full thing each time. This was scripted with the following small shell script: #!/bin/sh egrep -nHrl -e 'irqreturn_t[ ]*[(][*]' $* | while read i do echo $i perl -pi -e 's/irqreturn_t\s*[(]\s*[*]\s*([_a-zA-Z0-9]*)\s*[)]\s*[(]\s*int\s*,\s*void\s*[*]\s*[)]/irq_handler_t \1/g' $i || exit $? done Signed-Off-By: David Howells <dhowells@redhat.com>
2006-10-07[PATCH] m68k pt_regs fixesAl Viro
m68k_handle_int() split in two functions: __m68k_handle_int() takes pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs *. Places where we used to call m68k_handle_int() recursively with the same pt_regs have simply lost the second argument, the rest is switched to __m68k_handle_int(). The rest of patch is just dropping pt_regs * where needed. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
