Orson Zhai d644437a1d tools/testing/selftests/sysctl: Add pre-check to the value of writes_strict
Sysctl test will fail in some items if the value of /proc/sys/kernel
/sysctrl_writes_strict is 0 as the default value in kernel older than v4.5.

Make this test more robus and compatible with older kernel by checking and
update writes_strict value and restore it when test is done.

Mauro Carvalho Chehab fde662d9c3 kselftest.rst: do some adjustments after ReST conversion
Do some minor adjustments after ReST conversion:

- On most documents, we use prepend a "$ " before
  command line arguments;

- Prefer to use :: on the preceding line;

- Split a multi-paragraph description as such.

SeongJae Park dc816e5d84 selftest/intel_pstate/aperf: Use LDLIBS instead of LDFLAGS
Build of aperf fails as below:
```
gcc  -Wall -D_GNU_SOURCE   -lm  aperf.c  -o /tools/testing/selftests/intel_pstate/aperf
/tmp/ccKf3GF6.o: In function `main':
aperf.c:(.text+0x278): undefined reference to `sqrt'
collect2: error: ld returned 1 exit status
```

The faulure occurs because -lm was defined as LDFLAGS and implicit rule
of make places LDFLAGS before source file.  This commit fixes the
problem by using LDLIBS instead of LDFLAGS.

Masami Hiramatsu d7b91c0b1c selftests/ftrace: Reset ftrace filter on older kernel
Since older kernel didn't support separated instance of
set_ftrace_filter, if the test case set the filter in
an instance, it will propagate to top-level instance.
This means that the filter setting remains even if we
remove the instance, and will cause other tests failure.
To avoid this issue, reset the ftrace filter if we
detect the propagation.

Richard Narron 239e250e4a fs/ufs: Set UFS default maximum bytes per file
This fixes a problem with reading files larger than 2GB from a UFS-2
file system:

    https://bugzilla.kernel.org/show_bug.cgi?id=195721

The incorrect UFS s_maxsize limit became a problem as of commit
c2a9737f45 ("vfs,mm: fix a dead loop in truncate_inode_pages_range()")
which started using s_maxbytes to avoid a page index overflow in
do_generic_file_read().

That caused files to be truncated on UFS-2 file systems because the
default maximum file size is 2GB (MAX_NON_LFS) and UFS didn't update it.

Here I simply increase the default to a common value used by other file
systems.

Linus Torvalds 3c06e6cbdb TTY fix for 4.12-rc4
Here is a single tty core fix for 4.12-rc4.  It reverts a patch that a
 lot of people reported as causing lockdep and other warnings.  Right
 after I reverted this in my tree, it seems like another "correct" fix
 might have shown up, but it's too late in the release cycle to be
 messing with tty core locking, so let's just revert this for now to go
 back how things always have been and try it again for 4.13.

Pull tty fix from Greg KH:
 "Here is a single tty core fix for 4.12-rc4. It reverts a patch that a
  lot of people reported as causing lockdep and other warnings.

  Right after I reverted this in my tree, it seems like another
  "correct" fix might have shown up, but it's too late in the release
  cycle to be messing with tty core locking, so let's just revert this

Pull input subsystem fixes from Dmitry Torokhov:

 - a couple of regression fixes in synaptics and axp20x-pek drivers

 - try to ease transition from PS/2 to RMI for Synaptics touchpad users
   by ensuring we do not try to activate RMI mode when RMI SMBus support
   is not enabled, and nag users a bit to enable it

 - plus a couple of other changes that seemed worthwhile for this
   release

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: axp20x-pek - switch to acpi_dev_present and check for ACPI0011 too
  Input: axp20x-pek - only check for "INTCFD9" ACPI device on Cherry Trail
  Input: tm2-touchkey - use LEN_ON as boolean value instead of LED_FULL
  Input: synaptics - tell users to report when they should be using rmi-smbus
  Input: synaptics - warn the users when there is a better mode

Hans de Goede 0fd5f22109 Input: axp20x-pek - switch to acpi_dev_present and check for ACPI0011 too
acpi_dev_found checks that there is a matching ACPI node, but it
may be disabled (_STA method returns 0) in which case the
soc_button_array driver will not bind to it and axp20x-pek should
handle the power-button.

This commit switches from acpi_dev_found to acpi_dev_present to
avoid not registering an input-dev for the powerbutton when there
is a disabled PNP0C40 device.

The ACPI-6.0 standard defines a standard gpio button device using
the ACPI0011 HID replacing the custom PNP0C40 gpio device, many
newer devices define both PNP0C40 and ACPI0011 devices enabling one
or the other depending on whether the BIOS thinks it is going to boot
Android or Windows.

This commit adds a check for the ACPI0011 device, so that if
either device is present *and* enabled we don't register an input-dev
for the powerbutton.

Hans de Goede 8d4b313769 Input: axp20x-pek - only check for "INTCFD9" ACPI device on Cherry Trail
Commit 9b13a4ca8d ("Input: axp20x-pek - do not register input device
on some systems") added a check for the INTCFD9 ACPI device which also
handles the powerbutton as on some systems the powerbutton is connected
to both the PMIC, handled by axp20x-pek, and to a gpio on the SoC, handled
by soc_button_array which attaches itself to the INTCFD9 ACPI device.

Testing + comparing DSDTs has shown that this only happens on Cherry
Trail devices with an AXP288 PMIC, the AXP288 PMIC is also used on
Bay Trail devices but there the power button is only connected to
the PMIC and not handled by soc_button_array.

This means that the INTCFD9 check has caused a regression on Bay Trail
devices, causing power-button presses to no longer be seen.

This commit fixes this by limiting the check to devices where the ACPI
node for the AXP288 contains a _HRV (hardware revision) attribute with
a value of 3 which indicates we are dealing with a Cherry Trail platform.
