ARM: 8392/3: smp: Only expose /sys/.../cpuX/online if hotpluggable
Writes to /sys/.../cpuX/online fail if we determine the platform doesn't support hotplug for that CPU. Furthermore, if the cpu_die op isn't specified the system hangs when we try to offline a CPU and it comes right back online unexpectedly. Let's figure this stuff out before we make the sysfs nodes so that the online file doesn't even exist if it isn't (at least sometimes) possible to hotplug the CPU.
Add a new 'cpu_can_disable' op and repoint all 'cpu_disable' implementations at it because all implementers use the op to indicate if a CPU can be hotplugged or not in a static fashion. With PSCI we may need to add a 'cpu_disable' op so that the secure OS can be migrated off the CPU we're trying to hotplug. In this case, the 'cpu_can_disable' op will indicate that all CPUs are hotpluggable by returning true, but the 'cpu_disable' op will make a PSCI migration call and occasionally fail, denying the hotplug of a CPU. This shouldn't be any worse than x86 where we may indicate that all CPUs are hotpluggable but occasionally we can't offline a CPU due to check_irq_vectors_for_cpu_disable() failing to find a CPU to move vectors to.

ARM: 8029/1: mcpm: Rename the power_down_finish() functions to be less confusing
The name "power_down_finish" seems to be causing some confusion, because it suggests that this function is responsible for taking some action to cause the specified CPU to complete its power down.
This patch renames the affected functions to "wait_for_powerdown" and similar, since this function's intended purpose is just to wait for the hardware to finish a powerdown initiated by a previous cpu_power_down.

ARM: 7848/1: mcpm: Implement cpu_kill() to synchronise on powerdown
CPU hotplug and kexec rely on smp_ops.cpu_kill(), which is supposed to wait for the CPU to park or power down, and perform the last rites (such as disabling clocks etc., where the platform doesn't do this automatically).
kexec in particular is unsafe without performing this synchronisation to park secondaries. Without it, the secondaries might not be parked when kexec trashes the kernel.
There is no generic way to do this synchronisation, so a new mcpm platform_ops method power_down_finish() is added by this patch.
The new method is mandatory. A platform which provides no way to detect when CPUs are parked is likely broken.

arm: delete __cpuinit/__CPUINIT usage from all ARM users
The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h.
Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless.
This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.

ARM: 8392/3: smp: Only expose /sys/.../cpuX/online if hotpluggable Writes to /sys/.../cpuX/online fail if we determine the platform doesn't support hotplug for that CPU. Furthermore, if the cpu_die op isn't specified the system hangs when we try to offline a CPU and it comes right back online unexpectedly. Let's figure this stuff out before we make the sysfs nodes so that the online file doesn't even exist if it isn't (at least sometimes) possible to hotplug the CPU. Add a new 'cpu_can_disable' op and repoint all 'cpu_disable' implementations at it because all implementers use the op to indicate if a CPU can be hotplugged or not in a static fashion. With PSCI we may need to add a 'cpu_disable' op so that the secure OS can be migrated off the CPU we're trying to hotplug. In this case, the 'cpu_can_disable' op will indicate that all CPUs are hotpluggable by returning true, but the 'cpu_disable' op will make a PSCI migration call and occasionally fail, denying the hotplug of a CPU. This shouldn't be any worse than x86 where we may indicate that all CPUs are hotpluggable but occasionally we can't offline a CPU due to check_irq_vectors_for_cpu_disable() failing to find a CPU to move vectors to.

ARM: 8029/1: mcpm: Rename the power_down_finish() functions to be less confusing The name "power_down_finish" seems to be causing some confusion, because it suggests that this function is responsible for taking some action to cause the specified CPU to complete its power down. This patch renames the affected functions to "wait_for_powerdown" and similar, since this function's intended purpose is just to wait for the hardware to finish a powerdown initiated by a previous cpu_power_down.

ARM: 7848/1: mcpm: Implement cpu_kill() to synchronise on powerdown CPU hotplug and kexec rely on smp_ops.cpu_kill(), which is supposed to wait for the CPU to park or power down, and perform the last rites (such as disabling clocks etc., where the platform doesn't do this automatically). kexec in particular is unsafe without performing this synchronisation to park secondaries. Without it, the secondaries might not be parked when kexec trashes the kernel. There is no generic way to do this synchronisation, so a new mcpm platform_ops method power_down_finish() is added by this patch. The new method is mandatory. A platform which provides no way to detect when CPUs are parked is likely broken.

arm: delete __cpuinit/__CPUINIT usage from all ARM users The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.
