Pull ARM fixes from Russell King:
- Łukasz Stelmach spotted a couple of issues with the decompressor.
- a couple of kdump fixes found while testing kdump
- replace some perl with shell code
- resolve SIGFPE breakage
- kprobes fixes

You can build a kernel in a cross compiling environment that doesn't
have perl in the $PATH. Commit 429f7a062e broke that for 32 bit
ARM. Fix it.
As reported by Stephen Rothwell, it appears that the symbols can be
either part of the BSS section or absolute symbols depending on the
binutils version. When they're an absolute symbol, the $(( ))
operator errors out and the build fails. Fix this as well.

This series of patches contains one BUG fix for trace if
CONFIG_DEBUG_PREEMPT is enabled and a regression fix for omap1 FIQ
handling on ams-delta. Then there's a dts fix for missing SoC
compatible on ti81xx board dts files that did matter until we added
the clkctrl clocks and without that some clocks are now not found.
Then there are two logicpd-som-lv specific dts fixes that fix
misconfigured pins for WLAN and audio. Turns out we had to revert
the third one because it caused another regression for USB.

Fix LVDS output on Gen2 boards
Laurent Pincart says "This patch series fixes LVDS output support on the
Lager, Koelsh, Porter and Gose boards that broke in v4.17-rc1 due to the
combination of the R-Car DU LVDS driver rework and the DT move of all
on-SoC peripherals to a /soc node.
We could handle the problem in the R-Car DU LVDS DT backward compatibility
code, but that fix would only be used for v4.17 as in v4.18 the Gen2 DT
will move to the new LVDS DT bindings. I thus propose merging these three
patches in v4.17 already to fix the problem as this is the simplest
solution."

Commit 4c9a27a6c6 ("ARM: tegra: Fix ULPI regression on Tegra20") changed
"ulpi-link" clock from CDEV2 to PLL_P_OUT4. Turned out that PLL_P_OUT4 is
the parent of CDEV2 clock and original clock setup of "ulpi-link" was
correct. The reverted patch was fixing USB for one board and broke the
other, now Tegra's clk driver correctly sets parent for the CDEV2 clock
and hence patch could be reverted safely, restoring USB for all of the
boards.

The missing "compatible" entries are needed by drivers/clk/ti/clkctrl.c,
and without them the structures initialized in drivers/clk/ti/clk-814x.c
are not passed to configuration code. The result is a "not found from
clkctrl data" error message, although boot proceeds anyway.
The reason why the compatible is not found is because the board specific
files override the SoC compatible without including it. This did not
cause any issues until with the clkctrl nodes got introduced.
Very lightly tested on a (lurching) AM3874 design that's in the middle
of a kernel upgrade from TI's abandoned 2.6.37 tree.
Also tested on j5eco-evm and hp-t410 to verify the clkctrl clocks are
found.

The memory node has been changed to get rid of warnings
(see below). It contains the memory base address as that is
fixed for DA850 SoCs. But the size needs to be added by
bootloader or a board specific dts.
This gets rid of the following W=1 warnings:
arch/arm/boot/dts/da850-enbw-cmc.dtb: Warning (unit_address_vs_reg): /memory: node has a reg or ranges property, but no unit name
arch/arm/boot/dts/da850-evm.dtb: Warning (unit_address_vs_reg): /memory: node has a reg or ranges property, but no unit name

In commit f0842bc563 ("ARM: dts: sun8i: h3: Enable HDMI output on H3

line for the HDMI node, inadvertenly using the one for the EMAC. This
resulted in the EMAC now being disabled. Whether this was due to a
rebase error or some other mishap is unknown.
This patch re-enables the EMAC by adding the status line to its node.

The current (mildly evil) fsl_pq_mdio code uses an undocumented shadow of
the TBIPA register on LS1021A, which happens to be read-only.
Changing TBI PHY address therefore does not work on LS1021A.
The real (and documented) address of the TBIPA registere lies in the eTSEC
block and not in MDIO/MII, which is read/write, so using that fixes
the problem.

Calling __stack_chk_guard_setup() in decompress_kernel() is too late
that stack checking always fails for decompress_kernel() itself. So
remove __stack_chk_guard_setup() and initialize __stack_chk_guard before
we call decompress_kernel().
Original code comes from ARM but also used for MIPS and SH, so fix them
together. If without this fix, compressed booting of these archs will
fail because stack checking is enabled by default (>=4.16).

This release brings up a new platform based on the old ARM9 core: the
Nuvoton NPCM is used as a baseboard management controller, competing
with the better known ASpeed AST2xx series.
Another important change is the addition of ARMv7-A based chips
in mach-stm32. The older parts in this platform are ARMv7-M based
microcontrollers, now they are expanding to general-purpose workloads.
The other changes are the usual defconfig updates to enable additional
drivers, lesser bugfixes. The largest updates as often are the ongoing
OMAP cleanups, but we also have a number of changes for the older
PXA and davinci platforms this time.
For the Renesas shmobile/r-car platform, some new infrastructure
is needed to make the watchdog work correctly.
Supporting Multiprocessing on Allwinner A80 required a significant
amount of new code, but is not doing anything unexpected.

This is the usual set of changes for device trees, with over 700
non-merged changesets. There is an ongoing set of dtc warning fixes and
the usual bugfixes, cleanups and added device support.
The most interesting bit as usual is support for new machines listed
below:
- The Allwinner H6 makes its debut with the Pine-H64 board, and we get
two new machines based on its older siblings: the H5 based OrangePi
Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
Zero development board (based on H2).
- NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
development board and p2888 CPU module.
- The Nuvoton npcm750 is a BMC that was newly added, for now we only
support running on the evaluation board.
- STmicroelectronics stm32 gains support for the stm32mp157c and two
evaluation boards.
- The Toradex Colibri board family grows a few members based on the
i.MX6ULL variant.
- The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
family of chips.
- The Phytec phyBOARD Mira is a family of industrial boards based on
i.MX6. For now, four models get added.
- TI am335x based PDU-001 is an industrial embedded machine used for
traffic monitoring
- The Aspeed platform now supports running on the BMC on the Qualcomm
Centriq 2400 server
- Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
msm8974 based Galaxy S5 is a rather different phone made by the same
company.
- The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
for the various boards made by Xilinx themselves, as well as the
Digilent Zybo Z7.
- The ARM Versatile family now supports the "IB2" interface board.
- The Renesas H2 based "Stout" and the H3 based Salvator-X are more
evaluation boards named after a kind of beer, as most of them are.
The r8a77980 (V3H) based "Condor" apparently doesn't follow that

ARM: boot: add strrchr function
...
Commit ee333554fe ("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE")
introduced a new warning:
arch/arm/boot/compressed/misc.c: In function 'fortify_panic':
arch/arm/boot/compressed/misc.c:167:1: error: 'noreturn' function does return [-Werror]
The simple solution would be to make 'error' a noreturn function, but
this causes a prototype mismatch as the function is prototyped in
several .c files. So, move the function prototype to a new header.
There are also a couple of variables that are also declared in several
locations. Clean this up while we are here.

Here is the big set of Staging/IIO driver patches for 4.17-rc1.
It is a lot, over 500 changes, but not huge by previous kernel release
standards. We deleted more lines than we added again (27k added vs. 91k
remvoed), thanks to finally being able to delete the IRDA drivers and
networking code.
We also deleted the ccree crypto driver, but that's coming back in
through the crypto tree to you, in a much cleaned-up form.
Added this round is at lot of "mt7621" device support, which is for an
embedded device that Neil Brown cares about, and of course a handful of
new IIO drivers as well.
And finally, the fsl-mc core code moved out of the staging tree to the
"real" part of the kernel, which is nice to see happen as well.
Full details are in the shortlog, which has all of the tiny cleanup
patches described.
All of these have been in linux-next for a while with no reported
issues.

Here is the big set of tty and serial driver patches for 4.17-rc1
Not all that big really, most are just small fixes and additions to
existing drivers. There's a bunch of work on the imx serial driver
recently for some reason, and a new embedded serial driver added as
well.
Full details are in the shortlog.
All of these have been in the linux-next tree for a while with no
reported issues.
