8bb7844286 Add suspend-related notifications for CPU hotplug
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).

8a665a0552 hwmon: Only call vid_which_vrm() when needed
Some hardware monitoring drivers create the VID/VRM interface files
conditionally depending on the chip model or configuration. We should
only call vid_which_vrm() when we are actually going to create the
files. Not only it is more logical and efficient that way, but it also
prevents printing unnecessary warnings such as the one reported here:

ce7ee4e80a hwmon: Request the I/O regions in platform drivers
My understanding of the resource management in the Linux 2.6 device
driver model is that the devices should declare their resources, and
then when a driver attaches to a device, it should request the
resources it will be using, so as to mark them busy. This is how the
PCI and PNP subsystems work, you can clearly see the two levels of
resources (declaration and request) in /proc/ioports for these
devices.

So I believe that our platform hardware monitoring drivers should
follow the same logic. At the moment, we only declare the resources
but we do not request them. This patch adds the I/O region request
and release calls.

33725ad36d hwmon/w83627ehf: Fix the fan5 clock divider write
Users have been complaining about the w83627ehf driver flooding their logs
with debug messages like:

w83627ehf 9191-0a10: Increasing fan 4 clock divider from 64 to 128

or:

w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8

The reason is that we failed to actually write the LSB of the encoded clock
divider value for that fan, causing the next read to report the same old value
again and again.

Additionally, the fan number was improperly reported, making the bug harder to
find.

a117dddf6b hwmon/f71805f: Fix a race condition
I think I introduced a potential race condition bug with commit
51c997d80e. I didn't realize it
back then, but platform_device_put and platform_device_release
both appear to free the platform data associated with the device.
This makes an explicit kfree redundant at best, and maybe even
racy, as it might occur while someone still holds a reference
to the platform device.

37f54ee546 hwmon: Use subsys_initcall
Subsystem infrastructure should normally register with "subsys_initcall",
so that it's available to drivers that may need to initialize early.

This patch updates "hwmon" to do so.  It's common for embedded systems to
have multifunction chips with hardware monitoring interfaces, and to have
those chips be used during system bringup ... before a normal "module_init"
would kick, or maybe just linked so they'd init before hwmon.

7f999aa726 hwmon: Simplify the locking model of two drivers
Many hardware monitoring drivers use two different mutexes, one to
protect their per-device data structure, and one to protect the
access to the device registers. These mutexes are essentially
redundant, as the drivers are transfering values between the device
registers and the data cache, so they almost always end up holding
both mutexes at the same time. Using a single mutex will make the
code more simple and faster.

I am changing only two of the affected drivers here, the authors
of the other affected drivers are welcome to submit similar patches
if they want.

Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the
same as the Fintek F71805F/FG as far as hardware monitoring is concerned,
with two additional internal voltages monitored (VSB and battery), and 6
VID inputs (not yet supported.)

To make things a bit more confusing, two of the voltage input pins (in4
and in8) can be used for other functions. The driver reads the pin
configuration from the Super-I/O configuration space to decide whether
it must create interface files for these inputs or not.
