arm, arm64, mips, parisc, sh, x86 architectures use the same version of
hugetlb_free_pgd_range, so move this generic implementation into
asm-generic/hugetlb.h.

Pull Devicetree updates from Rob Herring:
"A bit bigger than normal as I've been busy this cycle.
There's a few things with dependencies and a few things subsystem
maintainers didn't pick up, so I'm taking them thru my tree.
The fixes from Johan didn't get into linux-next, but they've been
waiting for some time now and they are what's left of what subsystem
maintainers didn't pick up.
Summary:
- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4
- Work to get rid of direct accesses to struct device_node name and
type pointers in preparation for removing them. New helpers for
parsing DT cpu nodes and conversions to use the helpers. printk
conversions to %pOFn for printing DT node names. Most went thru
subystem trees, so this is the remainder.
- Fixes to DT child node lookups to actually be restricted to child
nodes instead of treewide.
- Refactoring of dtb targets out of arch code. This makes the support
more uniform and enables building all dtbs on c6x, microblaze, and
powerpc.
- Various DT binding updates for Renesas r8a7744 SoC
- Vendor prefixes for Facebook, OLPC
- Restructuring of some ARM binding docs moving some peripheral
bindings out of board/SoC binding files
- New "secure-chosen" binding for secure world settings on ARM
- Dual licensing of 2 DT IRQ binding headers"

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo updates from Eric Biederman:
"I have been slowly sorting out siginfo and this is the culmination of
that work.
The primary result is in several ways the signal infrastructure has
been made less error prone. The code has been updated so that manually
specifying SEND_SIG_FORCED is never necessary. The conversion to the
new siginfo sending functions is now complete, which makes it
difficult to send a signal without filling in the proper siginfo
fields.
At the tail end of the patchset comes the optimization of decreasing
the size of struct siginfo in the kernel from 128 bytes to about 48
bytes on 64bit. The fundamental observation that enables this is by
definition none of the known ways to use struct siginfo uses the extra
bytes.
This comes at the cost of a small user space observable difference.
For the rare case of siginfo being injected into the kernel only what
can be copied into kernel_siginfo is delivered to the destination, the
rest of the bytes are set to 0. For cases where the signal and the
si_code are known this is safe, because we know those bytes are not
used. For cases where the signal and si_code combination is unknown
the bits that won't fit into struct kernel_siginfo are tested to
verify they are zero, and the send fails if they are not.
I made an extensive search through userspace code and I could not find
anything that would break because of the above change. If it turns out
I did break something it will take just the revert of a single change
to restore kernel_siginfo to the same size as userspace siginfo.
Testing did reveal dependencies on preferring the signo passed to
sigqueueinfo over si->signo, so bit the bullet and added the
complexity necessary to handle that case.
Testing also revealed bad things can happen if a negative signal
number is passed into the system calls. Something no sane application
will do but something a malicious program or a fuzzer might do. So I
have fixed the code that performs the bounds checks to ensure negative
signal numbers are handled"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.20 series:
Core changes:
- A patch series from Hans Verkuil to make it possible to
enable/disable IRQs on a GPIO line at runtime and drive GPIO lines
as output without having to put/get them from scratch.
The irqchip callbacks have been improved so that they can use only
the fastpatch callbacks to enable/disable irqs like any normal
irqchip, especially the gpiod_lock_as_irq() has been improved to be
callable in fastpath context.
A bunch of rework had to be done to achieve this but it is a big
win since I never liked to restrict this to slowpath. The only call
requireing slowpath was try_module_get() and this is kept at the
.request_resources() slowpath callback. In the GPIO CEC driver this
is a big win sine a single line is used for both outgoing and
incoming traffic, and this needs to use IRQs for incoming traffic
while actively driving the line for outgoing traffic.
- Janusz Krzysztofik improved the GPIO array API to pass a "cookie"
(struct gpio_array) and a bitmap for setting or getting multiple
GPIO lines at once.
This improvement orginated in a specific need to speed up an OMAP1
driver and has led to a much better API and real performance gains
when the state of the array can be used to bypass a lot of checks
and code when we want things to go really fast.
The previous code would minimize the number of calls down to the
driver callbacks assuming the CPU speed was orders of magnitude
faster than the I/O latency, but this assumption was wrong on
several platforms: what we needed to do was to profile and improve
the speed on the hot path of the array functions and this change is
now completed.
- Clean out the painful and hard to grasp BNF experiments from the
device tree bindings. Future approaches are looking into using JSON
schema for this purpose. (Rob Herring is floating a patch series.)
New drivers:
- The RCAR driver now supports r8a774a1 (RZ/G2M).
- Synopsys GPIO via CREGs driver.
Major improvements:
- Modernization of the EP93xx driver to use irqdomain and other
contemporary concepts.
- The ingenic driver has been merged into the Ingenic pin control
driver and removed from the GPIO subsystem.
- Debounce support in the ftgpio010 driver"

Krait CPUs have a handful of L2 cache controller registers that
live behind a cp15 based indirection register. First you program
the indirection register (l2cpselr) to point the L2 'window'
register (l2cpdr) at what you want to read/write. Then you
read/write the 'window' register to do what you want. The
l2cpselr register is not banked per-cpu so we must lock around
accesses to it to prevent other CPUs from re-pointing l2cpdr

"ARM: SoC fixes for 4.19
Two last minute bugfixes, both for NXP platforms:
* The Layerscape 'qbman' infrastructure suffers from probe ordering
bugs in some configurations, a two-patch series adds a hotfix for
this. 4.20 will have a longer set of patches to rework it.
* The old imx53-qsb board regressed in 4.19 after the addition
of cpufreq support, adding a set of explicit operating points
fixes this."

Enabling CONFIG_GCOV_PROFILE_ALL=y causes linker errors on ARM:
`.text.exit' referenced in section `.ARM.exidx.text.exit':
defined in discarded section `.text.exit'
`.text.exit' referenced in section `.fini_array.00100':
defined in discarded section `.text.exit'
And related errors on NDS32:
`.text.exit' referenced in section `.dtors.65435':
defined in discarded section `.text.exit'
The gcov compiler flags cause certain compiler versions to generate
additional destructor-related sections that are not yet handled by the
linker script, resulting in references between discarded and
non-discarded sections.
Since destructors are not used in the Linux kernel, fix this by
discarding these additional sections.

On at least x86 and ARM64, and as documented in the ptrace man page
a skipped system call will still cause a syscall exit ptrace stop.
Previous to this commit 32-bit ARM did not, resulting in strace
being confused when seccomp skips system calls.
This change also impacts programs that use ptrace to skip system calls.

Not all boards use two ethernet devices and/or use them in different
order. As almost all in-tree boards already define their own ethernet
aliases, remove them from the dtsi and add the aliases to the two boards,
that are missing their own definition.

The OMAP HSMMC driver has some elaborate and hairy handling for
passing GPIO card detect and write protect lines from a boardfile
into the driver: the machine defines a struct omap2_hsmmc_info
that is copied into struct omap_hsmmc_platform_data by
omap_hsmmc_pdata_init() in arch/arm/mach-omap2/hsmmc.c.
However the .gpio_cd and .gpio_wp fields are not copied from
omap2_hsmmc_info to omap_hsmmc_platform_data by
omap_hsmmc_pdata_init() so they remain unused. The only platform
defining omap2_hsmmc_info also define both to -1, unused.
It turn out there are no boardfiles passing any valid GPIO
lines into the OMAP HSMMC driver at all. And since we are not
going to add any more OMAP2 boardfiles, we can delete this
card detect and write protect handling altogether.
This seems to also fix a bug: the card detect callback
mmc_gpio_get_cd() in the slot GPIO core needs to be called
by drivers utilizing slot GPIO. It appears the the boardfile
quirks were not doing this right, so this would only get
called for boardfiles, i.e. since no boardfile was using it,
never.
Just assign mmc_gpio_get_cd() unconditionally to omap_hsmmc_ops
.get_cd() so card detects from the device tree works.
AFAICT card detect with GPIO lines assigned from
mmc_of_parse() are not working at the moment, but that is
no regression since it probably never worked.

All the machines using the MMCI are passing GPIOs for the
card detect and write protect using the device tree or
descriptor table (one single case, Integrator/AP IM-PD1).
Drop support for passing global GPIO numbers through
platform data, noone is using it.
