alpha: irq: remove deprecated use of IRQF_DISABLED

2013-04-07T19:59:30Z

Interrupt handlers are always invoked with interrupts disabled, so remove all uses of the deprecated IRQF_DISABLED flag. Cc: Richard Henderson Cc: Ivan Kokshaysky Reviewed-by: Matt Turner Signed-off-by: Will Deacon Signed-off-by: Michael Cree Signed-off-by: Linus Torvalds

alpha: irq: run all handlers with interrupts disabled

2013-04-07T19:59:30Z

Linux has expected that interrupt handlers are executed with local interrupts disabled for a while now, so ensure that this is the case on Alpha even for non-device interrupts such as IPIs. Without this patch, secondary boot results in the following backtrace: warning: at kernel/softirq.c:139 __local_bh_enable+0xb8/0xd0() trace: __local_bh_enable+0xb8/0xd0 irq_enter+0x74/0xa0 scheduler_ipi+0x50/0x100 handle_ipi+0x84/0x260 do_entint+0x1ac/0x2e0 irq_exit+0x60/0xa0 handle_irq+0x98/0x100 do_entint+0x2c8/0x2e0 ret_from_sys_call+0x0/0x10 load_balance+0x3e4/0x870 cpu_idle+0x24/0x80 rcu_eqs_enter_common.isra.38+0x0/0x120 cpu_idle+0x40/0x80 rest_init+0xc0/0xe0 _stext+0x1c/0x20 A similar dump occurs if you try to reboot using magic-sysrq.
