This patch introduces a new thermal cooling device based on common clock
framework. The original motivation to write this cooling device is to be
able to cool down thermal zones using clocks that feed co-processors, such
as GPUs, DSPs, Image Processing Co-processors, etc. But it is written
in a way that it can be used on top of any clock.

The implementation is pretty straight forward. The code creates
a thermal cooling device based on a pair of a struct device and a clock name.
The struct device is assumed to be usable by the OPP layer. The OPP layer
is used as source of the list of possible frequencies. The (cpufreq) frequency
table is then used as a map from frequencies to cooling states. Cooling
states are indexes to the frequency table.

The logic sits on top of common clock framework, specifically on clock
pre notifications. Any PRE_RATE_CHANGE is hijacked, and the transition is
only allowed when the new rate is within the thermal limit (cooling state -> freq).

When a thermal cooling device state transition is requested, the clock
is also checked to verify if the current clock rate is within the new
thermal limit.

md_check_recovery will skip any recovery and also clear
MD_RECOVERY_NEEDED if MD_RECOVERY_FROZEN is set.
So when we clear _FROZEN, we must set _NEEDED and ensure that
md_check_recovery gets run.
Otherwise we could miss out on something that is needed.

In particular, this can make it impossible to remove a
failed device from an array is the  'recovery-needed' processing
didn't happen.

Al Viro pointed out that the x86-64 csum_partial_copy_from_user() is
somewhat confused about what it should do on errors, notably it mostly
clears the uncopied end result buffer, but misses that for the initial
alignment case.

All users should check for errors, so it's dubious whether the clearing
is even necessary, and Al also points out that we should probably clean
up the calling conventions, but regardless of any future changes to this
function, the fact that it is inconsistent is just annoying.

So make the __get_user() failure path use the same error exit as all the
other errors do.

Sasha Levin reports:
 "gcc5 changes the default standard to c11, which makes kernel build
  unhappy

  Explicitly define the kernel standard to be gnu89 which should keep
  everything working exactly like it was before gcc5"

There are multiple small issues with the new default, but the biggest
issue seems to be that the old - and very useful - GNU extension to
allow a cast in front of an initializer has gone away.

Patch updated by Kirill:
 "I'm pretty sure all gcc versions you can build kernel with supports
  -std=gnu89.  cc-option is redunrant.

  We also need to adjust HOSTCFLAGS otherwise allmodconfig fails for me"

Note by Andrew Pinski:
 "Yes it was reported and both problems relating to this extension has
  been added to gnu99 and gnu11.  Though there are other issues with the
  kernel dealing with extern inline have different semantics between
  gnu89 and gnu99/11"

End result: we may be able to move up to a newer stdc model eventually,
but right now the newer models have some annoying deficiencies, so the
traditional "gnu89" model ends up being the preferred one.

  Specifics:

   - Fix a crash in the suspend-to-idle code path introduced by a recent

     dereferencing it (Dmitry Eremin-Solenikov).

   - Fix a boot crash on Exynos5 introduced by a recent commit making

     which exposed a weakness in the generic power domains framework
     leading to that crash (Ulf Hansson).

     CONFIG_OPP is not set.  This leads the cpufreq driver registration
     to fail, but the resume code attempts to restore the pre-suspend

Found by the UC-KLEE tool:  A user could supply less input to
firewire-cdev ioctls than write- or write/read-type ioctl handlers
expect.  The handlers used data from uninitialized kernel stack then.

This could partially leak back to the user if the kernel subsequently
generated fw_cdev_event_'s (to be read from the firewire-cdev fd)
which notably would contain the _u64 closure field which many of the
ioctl argument structures contain.

The fact that the handlers would act on random garbage input is a
lesser issue since all handlers must check their input anyway.

The fix simply always null-initializes the entire ioctl argument buffer
regardless of the actual length of expected user input.  That is, a
runtime overhead of memset(..., 40) is added to each firewirew-cdev
ioctl() call.  [Comment from Clemens Ladisch:  This part of the stack is
most likely to be already in the cache.]

Remarks:
  - There was never any leak from kernel stack to the ioctl output
    buffer itself.  IOW, it was not possible to read kernel stack by a
    read-type or write/read-type ioctl alone; the leak could at most
    happen in combination with read()ing subsequent event data.
  - The actual expected minimum user input of each ioctl from
    include/uapi/linux/firewire-cdev.h is, in bytes:
    [0x00] = 32, [0x05] =  4, [0x0a] = 16, [0x0f] = 20, [0x14] = 16,

A chapter is added to describe the trackpoint packets.

A section is added to describe the behaviour of the knob crc_enabled in
sysfs.

The introduction of the documentation only mentioned v1/v2, but in the
last part it already contains explanation of v3 and v4. The introduction
is updated.

The detection of crc_enabled is known to fail for Fujitsu H730. A DMI
blacklist is added for that, but it can be expected that other laptops will
pop up with this.

Here a sysfs knob is provided to alter the behaviour of crc_enabled.
Writing 0 or 1 to it sets the variable to 0 or 1. Reading it will show the
crc_enabled variable (0 or 1).

In the past, no elantech was known with 3 touchpad mouse buttons.
Fujitsu H730 is the first known elantech with a middle button. This commit
enables this middle button. For backwards compatibility, the Fujitsu is
detected via DMI, and only for this one 3 buttons will be announced.

Sometimes on Dell Latitude laptops psmouse/alps driver receive invalid ALPS
protocol V3 packets with bit7 set in last byte. More often it can be
reproduced on Dell Latitude E6440 or E7440 with closed lid and pushing
cover above touchpad.

If bit7 in last packet byte is set then it is not valid ALPS packet. I was
told that ALPS devices never send these packets. It is not know yet who
send those packets, it could be Dell EC, bug in BIOS and also bug in
touchpad firmware...

With this patch alps driver does not process those invalid packets, but
instead of reporting PSMOUSE_BAD_DATA, getting into out of sync state,
getting back in sync with the next byte and spam dmesg we return
PSMOUSE_FULL_PACKET. If driver is truly out of sync we'll fail the checks
on the next byte and report PSMOUSE_BAD_DATA then.
