ALPHA: drivers: remove __dev* attributes.

2013-01-03T23:57:13Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

alpha: Fix preemption handling in idle loop

2012-09-23T14:44:42Z

cpu_idle() is called on the boot CPU by the init code with preemption disabled. But the cpu_idle() function in alpha doesn't handle this when it calls schedule() directly. Fix it by converting it into schedule_preempt_disabled(). Also disable preemption before calling cpu_idle() from secondary CPU entry code to stay consistent with this state.

alpha: replace with new cpumask APIs

We plan to remove cpu_xx() old APIs. Thus convert them. This patch has no functional change. Signed-off-by: KOSAKI Motohiro Cc: Richard Henderson Cc: Ivan Kokshaysky Cc: Matt Turner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sched: Provide scheduler_ipi() callback in response to smp_send_reschedule()

2011-04-14T06:52:32Z

For future rework of try_to_wake_up() we'd like to push part of that function onto the CPU the task is actually going to run on. In order to do so we need a generic callback from the existing scheduler IPI. This patch introduces such a generic callback: scheduler_ipi() and implements it as a NOP. BenH notes: PowerPC might use this IPI on offline CPUs under rare conditions!

cpumask: arch_send_call_function_ipi_mask: alpha

2009-09-24T00:04:43Z

We're weaning the core code off handing cpumask's around on-stack. This introduces arch_send_call_function_ipi_mask(). We also take the chance to wean the send_ipi_message off the obsolescent for_each_cpu_mask(): making it take a pointer seemed the most natural way to do this. Signed-off-by: Rusty Russell
