There is no reason to remove the sysfs cpu files when the CPU is dead, they
can be removed when the cpu is prepared to go down. Doing it at
DOWN_PREPARE allows us to convert it to a symetric hotplug state in the
next step.

If the ONLINE callback fails, the driver does not any clean up right
away instead it waits to get to the DEAD stage to do it. Yes, it waits.
Since we don't pass the error code back to the caller, no one knows.
Do the clean up right away so it does not look like a leak.

The threshold_cpu_callback callbacks looks like one of the notifier and
its arguments are almost the same. Split this out and have one ONLINE
and one DEAD callback. This will come handy later once the main code
gets changed to use the callback mechanism.
Also, handle threshold_cpu_callback_online()
Part of the init (memory allocation and so on) is done
in mcheck_cpu_init(). While moving the the allocation to
mcheck_init_device() (where the hotplug calls are initialized) it
becomes necessary to move the callback (mcheck_cpu_init()), too.
The callback is now removed from identify_cpu() and reg
cpuhp_setup_state() invokes the startup callback on all online cpus with
the proper protection, so we can remove the cpu hotplug protection from the
init function and the creation of the per cpu files for online cpus in
smp_add_present_cpu(). smp_add_present_cpu() is called also called from
__smp_r
Move the threshold_create_device() so it can use
threshold_remove_device() without a a declaration.

The previous patch moved mcheck_cpu_init() out of identify_cpu() and put
it as the first CPU hotplug callback which is invoked on the target CPU
during bring up. It enables MCE and starts the MCE timer. If a CPU goes
down then those two things have to be reverted and this happens
currently in CPU_D
If we try a CPU down and fail in the middle then we roll back to the
online state. This means we would perform CPU_ONLINE()
without invoking CPU_DEAD() for the cleanup of what was allocated in
CPU_ONLINE.
Be prepared for this and don't allocate the struct if we have it
already.

This callback is still partly asymmetrical since the counterpart of
mce_device_create is done in CPU_DEAD.
On failure we don't undo mce_device_create() doing _but_ it will happen
once we move CPU_DEAD to the state machine.

The following patch introduces an annoying WARN
when a device is removed from the SAS topology:
[SCSI] libsas: prevent domain rediscovery competing with ata error handling
A sample WARN is as follows:

The Amlogic Meson GX SoCs uses a special register to store the
time in seconds to wakeup after a system suspend.
In order to be able to reuse the RTC wakealarm feature, this
driver implements a fake RTC device which uses the system time
to deduce a suspend delay.

Thie patchset is a very experiment patchset to support the System Suspend
feature of the Amlogic Meson GX SoCs.
These SoCs implements system suspend using a non-standard PSCI CPU_SUSPEND
parameter to enter system suspend.
A small driver is added to properly fill the platform_suspend_ops and make
