The IT8705F and related parts are Super I/O controllers that contain
many separate devices.
Some BIOSes describe IT8705F I/O port usage under a motherboard device
(PNP0C02) with overlapping regions, e.g., 0x290-0x29f and 0x290-0x294.
The it87 driver supports only the Environment Controller, which requires
only two ISA ports, but it used to request an eight-port range. If that
range exceeds a range reported by the BIOS, as 0x290-0x297 would, the
request fails, and the it87 driver cannot claim the device.
This patch makes the it87 driver request only the two ports used for the
Environment Controller device.
Systems where this problem has been reported:
Gigabyte GA-K8N Ultra 9
Gigabyte M56S-S3
Gigabyte GA-965G-DS3

The patch above increases the number of PNP port resources we support.
Prior to this patch, we ignored some port resources, which masked the
it87 problem.

The VID input level change has been reported to cause trouble. Be more
careful in this respect:
* Only change the level on the W83627EHF/EHG. The W83627DHG is more
complex in this respect.
* Don't change the level if the VID pins are in output mode.
* Only set the level to TTL if VRM 9.x is used.

It's not permitted to unregister a device after devices have been suspended.
It causes deadlocks to appear on systems with coretemp hwmon loaded. To avoid
this, we can make coretemp_cpu_callback() do nothing if the _FROZEN bit is set
in action.
Also, in other cases it's generally too late to unregister the coretemp device
if the CPU is already dead, so it should be unregistered on CPU_DOWN_PREPARE.

Allow initializing fans on systems where BIOS does not do that by
default.
- define f75375s_platform_data in new file f75375s.h
- if platform_data was provided, set fans accordingly in f75375_init()
- split set_pwm_enable() to a sysfs callback and directly usable
set_pwm_enable_direct()

Following the example of David Brownell's work on lm75:
- Create a second driver struct, using new-style driver binding methods.
- Rename the old driver struct as f75375_legacy_driver.
- Make the legacy bind/unbind logic delegate all its work.

At least the 2x Quad-Core Apple Mac Pro appears to have some over-heat
protection which suddenly powers off the whole box under load. This adds
support for the fans and temerature sensors in the Mac Pro - later some
"windwarm" a-like code should probably monitor the values. For now
manually tweaking the fans prevents the sudden shutdown for me.
cd /sys/devices/platform/applesmc.768
for x in fan{1,2,3,4}; do
echo 1 > ${x}_manual
echo 1285 > ${x}_output
done
Two sensors are 0, while four are 129 °C, those might be removed again,
later.

This hoists nr-1 offset out of (show|store)_temp_*(.*) callbacks, and into
SENSOR_DEVICE_ATTRs for sysfs tempN_X files. It also combines
temp[1] and temp_add[2] (array) fields in w83627hf_data into 3 elem arrays,
which simplifies special-case handling of nr, allowing simplification
of callback bodies and rerolling a flattened loop in
w83627hf_update_device(struct device *dev).
The array conversion changes temp[1] from u8 to u16, but this was
happening implicitly via the helper functions anyway.

cpu_data is currently an array defined using NR_CPUS. This means that
we overallocate since we will rarely really use maximum configured cpus.
When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.
These changes were adopted from the sparc64 (and ia64) code. An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index. This corresponds to the index into a cpumask_t as well as the
per_cpu index. It's used in various places like show_cpuinfo().
cpu_data is defined to be the boot_cpu_data structure for the NON-SMP
case.
