Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
 "As part of the cleanup of some remaining y2038 issues, I came to
  fs/compat_ioctl.c, which still has a couple of commands that need
  support for time64_t.

  In completely unrelated work, I spent time on cleaning up parts of
  this file in the past, moving things out into drivers instead.

  After Al Viro reviewed an earlier version of this series and did a lot
  more of that cleanup, I decided to try to completely eliminate the
  rest of it and move it all into drivers.

  This series incorporates some of Al's work and many patches of my own,
  but in the end stops short of actually removing the last part, which
  is the scsi ioctl handlers. I have patches for those as well, but they
  need more testing or possibly a rewrite"

This patch exports standard hwmon pwmX_enable sysfs attribute for
enabling or disabling automatic fan control by BIOS. Standard value
"1" is for disabling automatic BIOS fan control and value "2" for
enabling.

By default BIOS auto mode is enabled by laptop firmware.

When BIOS auto mode is enabled, custom fan speed value (set via hwmon
pwmX sysfs attribute) is overwritten by SMM in few seconds and
therefore any custom settings are without effect. So this is reason
why implementing option for disabling BIOS auto mode is needed.

So finally this patch allows kernel to set and control fan speed on
laptops, but it can be dangerous (like setting speed of other fans).

The SMM commands to enable or disable automatic fan control are not
documented and are not the same on all Dell laptops. Therefore a
whitelist is used to send the correct codes only on laptopts for which
they are known.

This patch was originally developed by Pali Rohár; later Giovanni
Mascellani implemented the whitelist.

monitor the supply voltage, supply current, power consumption
and provide one local and up to three (TMP513) remote temperature sensors.

It has been tested using a TI TMP513 development kit (TMP513EVM)

The ltc2947 is a high precision power and energy monitor with an
internal sense resistor supporting up to +/- 30A. Three internal no
Latency ADCs ensure accurate measurement of voltage and current, while
high-bandwidth analog multiplication of voltage and current provides
accurate power measurement in a wide range of applications. Internal or
external clocking options enable precise charge and energy measurements.

[groeck: Removed unnecessary checks when reading temperature and energy;

This patch implements the summation feature of INA3221, mainly the
SCC (enabling) and SF (warning flag) bits of MASK_ENABLE register,
INA3221_SHUNT_SUM (summation of shunt voltages) register, and the
INA3221_CRIT_SUM (its critical alert setting) register.

Although the summation feature allows user to select which channels
to be added to the result, as an initial support, this patch simply
selects all channels by default, with one only condition: all shunt
resistor values need to be the same. This is because the summation
of current channels can be only accurately calculated, using shunt
voltage sum register, if all shunt resistors are equivalent.

Our driver configures the device to read at 2Hz, but then only allows the
user to read cached temp values at up to 0.5Hz. Let's allow users to read
as quickly as we do.

The variable res is being initialized with a value that
is never read and is being re-assigned a little later on. The
assignment is redundant and hence can be removed.
