Add more determinism to initial namespace device-name assignments by

If label scanning finds multiple valid pmem namespaces allow them to be
surfaced rather than fail namespace scanning. Support for creating
multiple namespaces per region is saved for a later patch.
Note that this adds some new error messages to clarify which of the pmem
namespaces in the set are potentially impacted by invalid labels.

Pull namespace updates from Eric Biederman:
"This set of changes is a number of smaller things that have been
overlooked in other development cycles focused on more fundamental
change. The devpts changes are small things that were a distraction
until we managed to kill off DEVPTS_MULTPLE_INSTANCES. There is an
trivial regression fix to autofs for the unprivileged mount changes
that went in last cycle. A pair of ioctls has been added by Andrey
Vagin making it is possible to discover the relationships between
namespaces when referring to them through file descriptors.
The big user visible change is starting to add simple resource limits
to catch programs that misbehave. With namespaces in general and user
namespaces in particular allowing users to use more kinds of
resources, it has become important to have something to limit errant
programs. Because the purpose of these limits is to catch errant
programs the code needs to be inexpensive to use as it always on, and
the default limits need to be high enough that well behaved programs
on well behaved systems don't encounter them.
To this end, after some review I have implemented per user per user
namespace limits, and use them to limit the number of namespaces. The
limits being per user mean that one user can not exhause the limits of
another user. The limits being per user namespace allow contexts where
the limit is 0 and security conscious folks can remove from their
threat anlysis the code used to manage namespaces (as they have
historically done as it root only). At the same time the limits being
per user namespace allow other parts of the system to use namespaces.
Namespaces are increasingly being used in application sand boxing
scenarios so an all or nothing disable for the entire system for the
security conscious folks makes increasing use of these sandboxes
impossible.
There is also added a limit on the maximum number of mounts present in
a single mount namespace. It is nontrivial to guess what a reasonable
system wide limit on the number of mount structure in the kernel would
be, especially as it various based on how a system is using
containers. A limit on the number of mounts in a mount namespace
however is much easier to understand and set. In most cases in
practice only about 1000 mounts are used. Given that some autofs
scenarious have the potential to be 30,000 to 50,000 mounts I have set
the default limit for the number of mounts at 100,000 which is well
above every known set of users but low enough that the mount hash
tables don't degrade unreaonsably.
These limits are a start. I expect this estabilishes a pattern that
other limits for resources that namespaces use will follow. There has
been interest in making inotify event limits per user per user
namespace as well as interest expressed in making details about what
is going on in the kernel more visible"

The other main chunk of code is some preparation for the upcoming

Speaking of reflink, I'm currently planning to send you another pull

When nfsd calls fh_to_dentry, it expect ESTALE or ENOMEM as errors.
In particular it can be tempting to return ENOENT, but this is not
handled well by nfsd.
Rather than requiring strict adherence to error code code filesystems,
treat all unexpected error codes the same as ESTALE. This is safest.

iov_iter variant for passing data into pipe. copy_to_iter()
copies data into page(s) it has allocated and stuffs them into
the pipe; copy_page_to_iter() stuffs there a reference to the
page given to it. Both will try to coalesce if possible.
iov_iter_zero() is similar to copy_to_iter(); iov_iter_get_pages()
and friends will do as copy_to_iter() would have and return the
pages where the data would've been copied. iov_iter_advance()
will truncate everything past the spot it has advanced to.
New primitive: iov_iter_pipe(), used for initializing those.
pipe should be locked all along.
Running out of space acts as fault would for iovec-backed ones;
in other words, giving it to ->read_iter() may result in short
read if the pipe overflows, or -EFAULT if it happens with nothing
copied there.
In other words, ->read_iter() on those acts pretty much like
->splice_read(). Moreover, all generic_file_splice_read() users,
as well as many other ->splice_read() instances can be switched
to that scheme - that'll happen in the next commit.

Pull staging and IIO updates from Greg KH:
"Here is the big staging and IIO driver pull request for 4.9-rc1.
There are a lot of patches in here, the majority due to the
drivers/staging/greybus/ subsystem being merged in with full
development history that went back a few years, in order to preserve
the work that those developers did over time.
Lots and lots of tiny cleanups happened in the tree as well, due to
the Outreachy application process and lots of other developers showing
up for the first time to clean code up. Along with those changes, we
deleted a wireless driver, and added a raspberrypi driver (currently
marked broken), and lots of new iio drivers.
Overall the tree still shrunk with more lines removed than added,
about 10 thousand lines removed in total. Full details are in the very
long shortlog below.
All of this has been in the linux-next tree with no issues. There will
be some merge problems with other subsystem trees, but those are all

slightly older version, but the same tree), so even though Ara is not
alive in the same form, the functionality is happening. We are working
with the developers of that phone to merge the newer stuff in with
their fork so they can use the upstream version in future versions of
their phone product line.
Toshiba has at least one chip shipping in their catalog that
needs/uses this protocol over a Unipro link, and rumor has it that
there might be more in the future.
There are also other users of the greybus protocols, there is a talk
next week at ELC that shows how it is being used across a network
connection to control a device, and previous ELC talks have showed the
protocol stack being used over USB to drive embedded Linux boards.
I've also talked to some people who are starting to work to add a host
controller driver to control arduinos as the greybus PHY protocols are
very useful to control a serial/i2c/spio/whatever device across a
random physical link, as it is a way to have a self-describing device
be attached to a host without needing manual configuration.
So yes, people are using it, and there is still the chance that it
will show up in a phone/laptop/tablet/whatever from Google in the
future as well, the tech isn't dead, even if the original large phone
project happens to be"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.9 series:
Subsystem improvements:
- do away with the last users of the obsolete Kconfig options
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
always sounded like an item on a wishlist to Santa Claus to me). We
can now select GPIOLIB and be done with it, for all archs. After
some struggle it even work on UM. Not that it has GPIO, but if it
wants to, it can select the library.
- continued efforts to make drivers properly either tristate or bool.
- introduce a warning for drivers assigning default triggers to their
irqchip lines when probed from device tree, so we find and fix
these ambigous drivers. It is agreed that in the OF config path,
the device tree defines trigger characteristics.
- the same warning, mutatis mutandis, for ACPI-probed GPIO irqchips.
- we introduce the ability to mark certain IRQ lines as "unusable" as
they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is put to
good use in the STMPE driver and also in the Cherryview pin control
driver.
- a new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM with
allyesconfig or allmodconfig it exploded in their face.
- move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so now
eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- new driver for the Aspeed GPIO front-end companion to the pin
controller merged through the pin control tree.
- new driver for the LP873x PMIC GPIO portions.
- new driver for Technologic Systems' I2C FPGA GPIO such as TS4900,
TS-7970, TS-7990 and TS-4100.
- new driver for the Broadcom BCM63xx series including BCM6338 and
BCM6345.
- new driver for the Intel WhiskeyCove PMIC GPIO.
- new driver for the Allwinner AXP209 PMIC GPIO portions.
- new driver for Diamond Systems 48 line GPIO-MM, another of these
port-mapped I/O expansion cards.
- support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- the STMPE driver now supports rising/falling edge detection
properly for IRQs.
- the PCA954x will now fetch and enable its VCC regulator properly.
- major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- switch the IOP driver to use the generic MMIO GPIO library.
- move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
over to this subsystem from MFD, achieveing some separation of
concerns"

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.9 cycle.
General improvements:
- nicer debugfs output with one pin/config pair per line.
- continued efforts to strictify module vs bool.
- constification and similar from Coccinelle engineers.
- return error from pinctrl_bind_pins()
- pulling in the ability to selectively disable mapping of unusable
IRQs from the GPIO subsystem.

- new driver for the Aspeed pin controller family: AST2400 (G4) and
AST2500 (G5) are supported. These are used by OpenBMC on the IBM
Witherspoon platform.
- new subdriver for the Allwinner sunxi GR8.
Driver improvements:
- drop default IRQ trigger types assigned during IRQ mapping on AT91
and Nomadik. This error was identified by improvements in the IRQ
core by Marc Zyngier.
- active high/low types on the GPIO IRQs for the ST pin controller.
- IRQ support on GPIOs on the STM32 pin controller.

RIP page_cache_tree_insert+0xf1/0x100
This is a long-standing bug in the way shadow entries are accounted in
the radix tree nodes. The shrinker needs to know when radix tree nodes
contain only shadow entries, no pages, so node->count is split in half
to count shadows in the upper bits and pages in the lower bits.
Unfortunately, the radix tree implementation doesn't know of this and
assumes all entries are in node->count. When there is a shadow entry
directly in root->rnode and the tree is later extended, the radix tree
implementation will copy that entry into the new node and and bump its
node->count, i.e. increases the page count bits. Once the shadow gets
removed and we subtract from the upper counter, node->count underflows
and triggers the warning. Afterwards, without node->count reaching 0
again, the radix tree node is leaked.
Limit shadow entries to when we have actual radix tree nodes and can
count them properly. That means we lose the ability to detect refaults
from files that had only the first page faulted in at eviction time.
Fixes: 449dd6984d ("mm: keep page cache radix tree nodes in check")

Pull regmap updates from Mark Brown:
"Another quiet release, a few small extensions to the set of register
maps we support and an improvement in the debugfs code:
- allow viewing of cached contents for write only registers via
debugfs.
- support a wider range of read/write flag masks in register formats.
- support more little endian formats"

Pull clk framework updates from Stephen Boyd:
"The core clk framework changes are small again. They're mostly minor
fixes that weren't causing enough problems (or any problems when we're
just clarifying things) to warrant sending outside the merge window.
The majority of changes are in drivers for various SoCs. Full details
are in the logs, but here's the summary.
Core:
- Better support for DeviceTree overlays with the addition of the
CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver for a
device node that matched during of_clk_init(), unless the driver
uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE. This allows
overlays to work cleanly for drivers that must probe before the
device model is ready, and also after it's ready when an overlay is
loaded.
- Clarification in the code around how clk_hw pointers are returned
from of clk providers
- Proper migration of prepare/enable counts to parents when the clk
tree is constructed
New Drivers:
- Socionext's UniPhier SoCs
- Loongson1C
- ZTE ZX296718
- Qualcomm MDM9615
- Amlogic GXBB AO clocks and resets
- Broadcom BCM53573 ILP
- Maxim MAX77620
Updates:
- Four Allwinner SoCs are migrated to the new style clk driver (A31,
A31s, A23 and A33)
- Exynos 5xxx audio and DRAM clks
- Loongson1B AC97, DMA and NAND clks
- Rockchip DDR clks and rk3399 driver tweaks
- Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer
clks
- Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W
- Amlogic GXBB MMC gate clks
- at91 sama5d4 sckc
- Removal of STiH415 and STiH416 clk support as the SoC is being
removed
- Rework of STiH4xx clk support for new style bindings
- Continuation of driver migration to clk_hw based registration APIs
- xgene PMD support
- bcm2835 critical clk markings
- ARM versatile ICST"

The McPDM in OMAP4/5 is using the pdmclk from twl6040 as functional clock.
The twl6040-pdmclk driver provides a clock which can be used to make sure
that the pdmclk is active when the McPDM is in use.

Due to the lack of parity in the way array fields have been named/
numbered, a mistake was made where more debug fields were declared
than actually existed. In doing so, 2 fields were added, which
although unclear, were already declared in the array. The result
was that the latter declarations trashed the former ones.
This patch places the array back in the correct order and removes
the offending NULL entries.
While we're at it, let's ensure this doesn't happen again by naming
each field properly and add a new *_LAST define to describe how
many fields there should be.

When building with -Woverride-init, we get a warning about an incorrect
initializer:
drivers/mfd/rk808.c:244:8: error: initialized field overwritten [-Werror=override-init]
[RK818_IRQ_DISCHG_ILIM] = {
This is clearly a mistake, as both RK818_IRQ_DISCHG_ILIM and RK818_IRQ_USB_OV
are defined as '7', but they refer to different register bits. Changing
RK818_IRQ_DISCHG_ILIM to 15 is consistent with how all other 14 interrupts are
handled here, so I'm assuming this is what it should have been.

Add support for handling IRQs: power button, AC and USB power state
changes. Mask and interrupt bits are shared within one register, which
prevents us to use regmap_irq implementation. New irq_domain is created in
order to add interrupt handling for each tps65217's subsystem. IRQ
resources have been added for charger subsystem to be able to notify about
AC and USB state changes.
