If the Super-I/O device is disabled, it is likely the BIOS has a good
reason for leaving it disabled, so give a warning when enabling it --
it's not likely to be wired correctly or be able to give good data.
Also, if the Super-I/O device is configured with an address of 0, the
driver refuses to initialize it.

Fix a potential race condition when some hardware monitoring platform
drivers are being unloaded. I believe that the driver data pointer
shouldn't be cleared before all the sysfs files are removed, otherwise
a sysfs callback might attempt to dereference a NULL pointer. I'm not
sure exactly what the driver core protects drivers against, so let's
play it safe.
While we're here, clear the driver data pointer when probe fails, so
as to not leave an invalid pointer behind us.

We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:
in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault
Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.
We want a single naming scheme, and everyone seems to prefer the
shorter variant, so let's go for it.

Since nonboot CPUs are now disabled after tasks and devices have been
frozen and the CPU hotplug infrastructure is used for this purpose, we need
special CPU hotplug notifications that will help the CPU-hotplug-aware
subsystems distinguish normal CPU hotplug events from CPU hotplug events
related to a system-wide suspend or resume operation in progress. This
patch introduces such notifications and causes them to be used during
suspend and resume transitions. It also changes all of the
CPU-hotplug-aware subsystems to take these notifications into consideration
(for now they are handled in the same way as the corresponding "normal"
ones).
