alpha: delete non-required instances of

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

alpha: irq: run all handlers with interrupts disabled

2013-04-07T19:59:30+00:00

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.

alpha: Use generic show_interrupts()

2011-03-29T12:47:58+00:00

The only subtle difference is that alpha uses ACTUAL_NR_IRQS and prints the IRQF_DISABLED flag. Change the generic implementation to deal with ACTUAL_NR_IRQS if defined. The IRQF_DISABLED printing is pointless, as we nowadays run all interrupts with irqs disabled. Signed-off-by: Thomas Gleixner

alpha: kill off alpha_do_IRQ

Good riddance... Nuke a pile of redundant handlers that the generic code takes care of as well. Tested-by: Michael Cree Signed-off-by: Kyle McMartin Signed-off-by: Matt Turner

alpha: irq clean up

2011-01-17T04:42:12+00:00

Stop touching irq_desc[irq] directly, instead use accessor functions provided. Use irq_has_action instead of directly testing the irq_desc. Tested-by: Michael Cree Signed-off-by: Kyle McMartin Signed-off-by: Matt Turner
