Pull networking fixes from David Miller:

 1) The netlink attribute passed in to dev_set_alias() is not
    necessarily NULL terminated, don't use strlcpy() on it. From
    Alexander Potapenko.

 2) Fix implementation of atomics in arm64 bpf JIT, from Daniel
    Borkmann.

 3) Correct the release of netdevs and driver private data in certain
    circumstances.

 4) Sanitize netlink message length properly in decnet, from Mateusz
    Jurczyk.

 5) Don't leak kernel data in rtnl_fill_vfinfo() netlink blobs. From
    Yuval Mintz.

 6) Hash secret is never initialized in ipv6 ILA translation code, from
    Arnd Bergmann. I guess those clang warnings about unused inline
    functions are useful for something!

 7) Fix endian selection in bpf_endian.h, from Daniel Borkmann.

 8) Sanitize sockaddr length before dereferncing any fields in AF_UNIX
    and CAIF. From Mateusz Jurczyk.

 9) Fix timestamping for GMAC3 chips in stmmac driver, from Mario
    Molitor.

    Johannes Berg.

11) Fix locking in sctp_for_each_endpoint(), from Xin Long.

12) Fix wrong memset size on 32-bit in snmp6, from Christian Perle.

13) Fix use after free in ip_mc_clear_src(), from WANG Cong.

14) Fix regressions caused by ICMP rate limiting changes in 4.11, from
    Jesper Dangaard Brouer.

  There is a patch hitting drivers/firmware/* that I was uncertain to
  who actually manages, but I got Andy Shevchenko's and Dmitry Torokov's
  review tags on it and I trust them both 100% to do the right thing for
  Intel platform drivers.

  Summary:

     smoothly.

   - A fix for some bogus allocations in the generic group management

159a07604a net: fec: add post PHY reset delay DT property
Some PHY require to wait for a bit after the reset GPIO has been
toggled. This adds support for the DT property `phy-reset-post-delay`
which gives the delay in milliseconds to wait after reset.

If the DT property is not given, no delay is observed. Post reset delay
greater than 1000ms are invalid.

c477ebe21f mmc: dt: pwrseq-simple: Invent power-off-delay-us
During power off, after the GPIO pin has been asserted, some devices like
the Wifi chip from TI, Wl18xx, needs a delay before the host continues with
clock gating and turning off regulators as to follow a graceful shutdown
sequence.

Therefore invent an optional power-off-delay-us DT binding for
mmc-pwrseq-simple, to allow us to support this constraint.

The datasheet and application note does not mention an allowed range for
the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set
lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with
T5x06 touch.

So, lacking a known lower limit, we increase the range for thresholds,
and set the lower limit to 0. The documentation is updated accordingly.

1fccb73011 iTCO_wdt: all versions count down twice
The ICH9 is listed as having TCO v2, and indeed the behavior in the
datasheet corresponds to v2 (for example the NO_REBOOT flag is
accessible via the 16KiB-aligned Root Complex Base Address).

However, the TCO counts twice just like in v1; the documentation
of the SECOND_TO_STS bit says: "ICH9 sets this bit to 1 to indicate
that the TIMEOUT bit had been (or is currently) set and a second
timeout occurred before the TCO_RLD register was written. If this
bit is set and the NO_REBOOT config bit is 0, then the ICH9 will
reboot the system after the second timeout.  The same can be found
in the BayTrail (Atom E3800) datasheet, and even HOWTOs around
the Internet say that it will reboot after _twice_ the specified
heartbeat.

I did not find the Apollo Lake datasheet, but because v4/v5 has
a SECOND_TO_STS bit just like the previous version I'm enabling
this for Apollo Lake as well.

f369fdf4f6 Revert "ACPI / button: Remove lid_init_state=method mode"
This reverts commit ecb10b694b.

The only expected ACPI control method lid device's usage model is

 1. Listen to the lid notification,
 2. Evaluate _LID after being notified by BIOS,
 3. Suspend the system (if users configure to do so) after seeing "close".

It's not ensured that BIOS will notify OS after boot/resume, and
it's not ensured that BIOS will always generate "open" event upon
opening the lid.

But there are 2 wrong usage models:

 1. When the lid device is responsible for suspend/resume the system,
    userspace requires to see "open" event to be paired with "close" after
    the system is resumed, or it will suspend the system again.

 2. When an external monitor connects to the laptop attached docks,
    userspace requires to see "close" event after the system is resumed so
    that it can determine whether the internal display should remain dark
    and the external display should be lit on.

After we made default kernel behavior to be suitable for usage model 1,
users of usage model 2 start to report regressions for such behavior
change.

Reversion of button.lid_init_state=method doesn't actually reverts to old
default behavior as doing so can enter a regression loop, but facilitates
users to work the reported regressions around with
button.lid_init_state=method.

Pull thermal management updates from Zhang Rui:

 - Fix a problem where orderly_shutdown() is called for multiple times
   due to multiple critical overheating events raised in a short period
   by platform thermal driver. (Keerthy)

 - Introduce a backup thermal shutdown mechanism, which invokes
   kernel_power_off()/emergency_restart() directly, after
   orderly_shutdown() being issued for certain amount of time(specified
   via Kconfig). This is useful in certain conditions that userspace may
   be unable to power off the system in a clean manner and leaves the
   system in a critical state, like in the middle of driver probing
   phase. (Keerthy)

 - Introduce a new interface in thermal devfreq_cooling code so that the
   driver can provide more precise data regarding actual power to the
   thermal governor every time the power budget is calculated. (Lukasz
   Luba)

 - Introduce BCM 2835 soc thermal driver and northstar thermal driver,
   within a new sub-folder. (Rafał Miłecki)

 - Introduce DA9062/61 thermal driver. (Steve Twiss)

 - Remove non-DT booting on TI-SoC driver. Also add support to fetching
   coefficients from DT. (Keerthy)

 - Refactorf RCAR Gen3 thermal driver. (Niklas Söderlund)

 - Small fix on MTK and intel-soc-dts thermal driver. (Dawei Chien,
   Brian Bian)

Pull SCSI target updates from Nicholas Bellinger:
 "Things were a lot more calm than previously expected. It's primarily
  fixes in various areas, with most of the new functionality centering
  around TCMU backend driver work that Xiubo Li has been driving.

  Here's the summary on the feature side:

   - Make T10-PI verify configurable for emulated (FILEIO + RD) backends
    (Dmitry Monakhov)
   - Allow target-core/TCMU pass-through to use in-kernel SPC-PR logic
    (Bryant Ly + MNC)
   - Add TCMU support for growing ring buffer size (Xiubo Li + MNC)
   - Add TCMU support for global block data pool (Xiubo Li + MNC)

  and on the bug-fix side:

   - Fix COMPARE_AND_WRITE non GOOD status handling for READ phase
    failures (Gary Guo + nab)
   - Fix iscsi-target hang with explicitly changing per NodeACL
    CmdSN number depth with concurrent login driven session
    reinstatement.  (Gary Guo + nab)
   - Fix ibmvscsis fabric driver ABORT task handling (Bryant Ly)
   - Fix target-core/FILEIO zero length handling (Bart Van Assche)

  Also, there was an OOPs introduced with the WRITE_VERIFY changes that
  I ended up reverting at the last minute, because as not unusual Bart
  and I could not agree on the fix in time for -rc1. Since it's specific
  to a conformance test, it's been reverted for now.

  There is a separate patch in the queue to address the underlying
  control CDB write overflow regression in >= v4.3 separate from the
  WRITE_VERIFY revert here, that will be pushed post -rc1"

9786e34e0a MTD updates for 4.12-rc1:
NAND, from Boris:
 """
  - some minor fixes/improvements on existing drivers (fsmc, gpio, ifc,
    davinci, brcmnand, omap)
  - a huge cleanup/rework of the denali driver accompanied with core
    fixes/improvements to simplify the driver code
  - a complete rewrite of the atmel driver to support new DT bindings
    make future evolution easier
  - the addition of per-vendor detection/initialization steps to avoid
    extending the nand_ids table with more extended-id entries
 """
 
 SPI NOR, from Cyrille:
 """
 - fixes in the hisi SPI controller driver.
 - fixes in the intel SPI controller driver.
 - fixes in the Mediatek SPI controller driver.
 - fixes to some SPI flash memories not supported the Chip Erase command.
 - add support to some new memory parts (Winbond, Macronix, Micron, ESMT).

791a9a666d Kbuild UAPI header export updates for v4.12
Improvement of headers_install by Nicolas Dichtel.
 
 It has been long since the introduction of uapi directories,
 but the de-coupling of exported headers has not been completed.
 Headers listed in header-y are exported whether they exist in
 uapi directories or not.  His work fixes this inconsistency.
 
 All (and only) headers under uapi directories are now exported.
 The asm-generic wrappers are still exceptions, but this is a big
 step forward.

b5a53b61a2 Sort of on the quieter side this time, which is probably due more
to me not catching up as quickly on patch review than anything else.
 Overall it seems normal though, a few small changes to the core, mostly
 small non-critical fixes here and there as well as driver updates for new
 and existing hardware support. The biggest things are the TI clk driver
 rework to lay the groundwork for clkctrl support in the next merge window
 and the AmLogic audio/graphics clk support.
 
 Core:
  * clk_possible_parents debugfs file so we know which parents a clk
    could possibly have
  * Fix to make clk rate change notifiers stop on the first failure instead
    of continuing
 
 New Drivers:
  * Mediatek MT6797 SoCs
  * hi655x PMIC clks
  * AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
  * Allwinner H5 SoCs and PRCM hardware
 
 Updates:
  * Nvidia Tegra T210 cleanups and non-critical fixes
  * TI OMAP cleanups in preparation for clkctrl support
  * Trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
  * ZTE zx296718 SoC VGA clks
  * Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
  * Support for IDT VersaClock 5P49V5935
  * Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3 support
