MIPS: Add arch generic CPU hotplug

2009-06-24T17:34:40+00:00

Each platform has to add support for CPU hotplugging itself by providing suitable definitions for the cpu_disable and cpu_die of the smp_ops methods and setting SYS_SUPPORTS_HOTPLUG_CPU. A platform should only set SYS_SUPPORTS_HOTPLUG_CPU once all it's smp_ops definitions have the necessary changes. This patch contains the changes to the dummy smp_ops definition for uni-processor systems. Parts of the code contributed by Cavium Inc. Signed-off-by: Ralf Baechle

MIPS: Build fix - include into all smp_processor_id() users.

2009-06-24T17:34:39+00:00

Some of the were relying into smp.h being dragged in by another header which of course is fragile. uses smp_processor_id() only in macros and including smp.h there leads to an include loop, so don't change cpu-info.h. Signed-off-by: Ralf Baechle

MIPS: bug.h Build fix - include .

In the past this file somehow used to be dragged in. Signed-off-by: Ralf Baechle

MIPS: Add hibernation support

2009-06-17T10:06:31+00:00

[Ralf: SMP support requires CPU hotplugging which MIPS currently doesn't support. As implemented in this patch cache and tlb flushing will also be invoked with interrupts disabled so smp_call_function() will blow up in charming ways. So limit to !SMP.] Reviewed-by: Pavel Machek Reviewed-by: Yan Hua Reviewed-by: Arnaud Patard Reviewed-by: Atsushi Nemoto Signed-off-by: Wu Zhangjin Signed-off-by: Hu Hongbing Signed-off-by: Ralf Baechle

MIPS: Move Cavium CP0 hwrena impl bits to cpu-feature-overrides.h
