Implement vas_init() and vas_exit() functions for a new VAS module.
This VAS module is essentially a library for other device drivers
and kernel users of the NX coprocessors like NX-842 and NX-GZIP.
In the future this will be extended to add support for user space
to access the NX coprocessors.
VAS is currently only supported with 64K page size.

This adds a perl script to actually parse the MAINTAINERS file, clean up
some whitespace in it, warn about errors in it, and then properly sort
the end result.
My perl-fu is atrocious, so the script has basically been created by
randomly putting various characters in a pile, mixing them around, and
then looking it the end result does anything interesting when used as a

Prepping for scripting the MAINTAINERS file cleanup (and possible split)
showed a couple of cases where the headers for a couple of entries were
bogus.
There's a few different kinds of bogosities:
- the X-GENE SOC EDAC case was confused and split over two lines
- there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all
different things.
- the NOKIA N900 CAMERA SUPPORT" was duplicated
all of which were more obvious when you started doing associative arrays
in perl to track these things by the header (so that we can alphabetize
this thing properly, and so that we might split it up by the data too).

lib/atomic64_test.c: add a test that atomic64_inc_not_zero() returns an int
mm: fix overflow check in expand_upwards()
This adds a new stress test driver for kmod: the kernel module loader.
The new stress test driver, test_kmod, is only enabled as a module right
now. It should be possible to load this as built-in and load tests
early (refer to the force_init_test module parameter), however since a
lot of test can get a system out of memory fast we leave this disabled
for now.
Using a system with 1024 MiB of RAM can *easily* get your kernel OOM
fast with this test driver.
The test_kmod driver exposes API knobs for us to fine tune simple
request_module() and get_fs_type() calls. Since these API calls only
allow each one parameter a test driver for these is rather simple.
Other factors that can help out test driver though are the number of
calls we issue and knowing current limitations of each. This exposes
configuration as much as possible through userspace to be able to build
tests directly from userspace.
Since it allows multiple misc devices its will eventually (once we add a
knob to let us create new devices at will) also be possible to perform
more tests in parallel, provided you have enough memory.
We only enable tests we know work as of right now.

enabled by default:
# tools/testing/selftests/kmod/kmod.sh -t 0008
# tools/testing/selftests/kmod/kmod.sh -t 0009
To be sure to run them as intended please unload both of the modules:
o test_module
o xfs
And ensure they are not loaded on your system prior to testing them. If
you use these paritions for your rootfs you can change the default test
driver used for get_fs_type() by exporting it into your environment. For
example of other test defaults you can override refer to kmod.sh
allow_user_defaults().
Behind the scenes this is how we fine tune at a test case prior to
hitting a trigger to run it:
cat /sys/devices/virtual/misc/test_kmod0/config
echo -n "2" > /sys/devices/virtual/misc/test_kmod0/config_test_case
echo -n "ext4" > /sys/devices/virtual/misc/test_kmod0/config_test_fs
echo -n "80" > /sys/devices/virtual/misc/test_kmod0/config_num_threads
cat /sys/devices/virtual/misc/test_kmod0/config
echo -n "1" > /sys/devices/virtual/misc/test_kmod0/config_num_threads
Finally to trigger:
echo -n "1" > /sys/devices/virtual/misc/test_kmod0/trigger_config
The kmod.sh script uses the above constructs to build different test cases.
A bit of interpretation of the current failures follows, first two
premises:
a) When request_module() is used userspace figures out an optimized
version of module order for us. Once it finds the modules it needs, as
per depmod symbol dep map, it will finit_module() the respective
modules which are needed for the original request_module() request.
b) We have an optimization in place whereby if a kernel uses
request_module() on a module already loaded we never bother userspace
as the module already is loaded. This is all handled by kernel/kmod.c.
A few things to consider to help identify root causes of issues:
0) kmod 19 has a broken heuristic for modules being assumed to be
built-in to your kernel and will return 0 even though request_module()
failed. Upgrade to a newer version of kmod.
1) A get_fs_type() call for "xfs" will request_module() for "fs-xfs",
not for "xfs". The optimization in kernel described in b) fails to
catch if we have a lot of consecutive get_fs_type() calls. The reason
is the optimization in place does not look for aliases. This means two
consecutive get_fs_type() calls will bump kmod_concurrent, whereas
request_module() will not.
This one explanation why test case 0009 fails at least once for
get_fs_type().
2) If a module fails to load --- for whatever reason (kmod_concurrent
limit reached, file not yet present due to rootfs switch, out of
memory) we have a period of time during which module request for the
same name either with request_module() or get_fs_type() will *also*
fail to load even if the file for the module is ready.
This explains why *multiple* NULLs are possible on test 0009.
3) finit_module() consumes quite a bit of memory.
4) Filesystems typically also have more dependent modules than other
modules, its important to note though that even though a get_fs_type()
call does not incur additional kmod_concurrent bumps, since userspace
loads dependencies it finds it needs via finit_module_fd(), it *will*
take much more memory to load a module with a lot of dependencies.
Because of 3) and 4) we will easily run into out of memory failures with
certain tests. For instance test 0006 fails on qemu with 1024 MiB of RAM.
It panics a box after reaping all userspace processes and still not
having enough memory to reap.

Merge tag 'rtc-4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni:
"Here is the pull-request for the RTC subsystem for 4.13.
Subsystem:
- expose non volatile RAM using nvmem instead of open coding in many
drivers. Unfortunately, this option has to be enabled by default to
not break existing users.
- rtctest can now test for cutoff dates, showing when an RTC will
start failing to properly save time and date.
- new RTC registration functions to remove race conditions in drivers
Newly supported RTCs:
- Broadcom STB wake-timer
- Epson RX8130CE
- Maxim IC DS1308
- STMicroelectronics STM32H7
Drivers:
- ds1307: use regmap, use nvmem, more cleanups
- ds3232: temperature reading support
- gemini: renamed to ftrtc010
- m41t80: use CCF to expose the clock
- rv8803: use nvmem
- s3c: many cleanups
- st-lpc: fix y2106 bug"

Add support for the MIPS Boston development board to generic kernels,
which essentially amounts to:
- Adding the device tree source for the MIPS Boston board.
- Adding a Kconfig fragment which enables the appropriate drivers for
the MIPS Boston board.
With these changes in place generic kernels will support the board by
default, and kernels with only the drivers needed for Boston enabled can
be configured by setting BOARDS=boston during configuration. For
example:
$ make ARCH=mips 64r6el_defconfig BOARDS=boston

Pull Writeback error handling updates from Jeff Layton:
"This pile represents the bulk of the writeback error handling fixes
that I have for this cycle. Some of the earlier patches in this pile
may look trivial but they are prerequisites for later patches in the
series.
The aim of this set is to improve how we track and report writeback
errors to userland. Most applications that care about data integrity
will periodically call fsync/fdatasync/msync to ensure that their
writes have made it to the backing store.
For a very long time, we have tracked writeback errors using two flags
in the address_space: AS_EIO and AS_ENOSPC. Those flags are set when a
writeback error occurs (via mapping_set_error) and are cleared as a
side-effect of filemap_check_errors (as you noted yesterday). This
model really sucks for userland.
Only the first task to call fsync (or msync or fdatasync) will see the
error. Any subsequent task calling fsync on a file will get back 0
(unless another writeback error occurs in the interim). If I have
several tasks writing to a file and calling fsync to ensure that their
writes got stored, then I need to have them coordinate with one
another. That's difficult enough, but in a world of containerized
setups that coordination may even not be possible.
But wait...it gets worse!
The calls to filemap_check_errors can be buried pretty far down in the
call stack, and there are internal callers of filemap_write_and_wait
and the like that also end up clearing those errors. Many of those
callers ignore the error return from that function or return it to
userland at nonsensical times (e.g. truncate() or stat()). If I get
back -EIO on a truncate, there is no reason to think that it was
because some previous writeback failed, and a subsequent fsync() will
(incorrectly) return 0.
This pile aims to do three things:
1) ensure that when a writeback error occurs that that error will be
reported to userland on a subsequent fsync/fdatasync/msync call,
regardless of what internal callers are doing
2) report writeback errors on all file descriptions that were open at
the time that the error occurred. This is a user-visible change,
but I think most applications are written to assume this behavior
anyway. Those that aren't are unlikely to be hurt by it.
3) document what filesystems should do when there is a writeback
error. Today, there is very little consistency between them, and a
lot of cargo-cult copying. We need to make it very clear what
filesystems should do in this situation.
To achieve this, the set adds a new data type (errseq_t) and then
builds new writeback error tracking infrastructure around that. Once
all of that is in place, we change the filesystems to use the new
infrastructure for reporting wb errors to userland.
Note that this is just the initial foray into cleaning up this mess.
There is a lot of work remaining here:
1) convert the rest of the filesystems in a similar fashion. Once the
initial set is in, then I think most other fs' will be fairly
simple to convert. Hopefully most of those can in via individual
filesystem trees.
2) convert internal waiters on writeback to use errseq_t for
detecting errors instead of relying on the AS_* flags. I have some
draft patches for this for ext4, but they are not quite ready for
prime time yet.
This was a discussion topic this year at LSF/MM too. If you're
interested in the gory details, LWN has some good articles about this:

This update consists of:
-- TAP13 framework and changes to some tests to convert to TAP13.
Converting kselftest output to standard format will help identify
run to run differences and pin point failures easily. TAP13 format
has been in use for several years and the output is human friendly.
Please find the specification:
https://testanything.org/tap-version-13-specification.html
Credit goes to Tim Bird for recommending TAP13 as a suitable format,
and to Grag KH for kick starting the work with help from Paul Elder
and Alice Ferrazzi
The first phase of the TAp13 conversion is included in this update.
Future updates will include updates to rest of the tests.
-- Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.
-- Kselftest documnetation has been converted to ReST format. Document
now has a new home under Documentation/dev-tools.
-- kselftest_harness.h is now available for general use as a result of
Mickaël Salaün's work.
-- Several fixes to skip and/or fail tests gracefully on older releases.

- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO line
may loose its state during suspend/resume of the system to save
power. This is used in the Wolfson Micro Arizona driver.
- ACPI-based GPIO was tightened up a lot around the edges.
- Use bitmap_fill() to speed up a loop.
New drivers:
- Exar XRA1403 SPI-based GPIO.
- MVEBU driver now supports Armada 7K and 8K.
- LP87565 PMIC GPIO.
- Renesas R-CAR R8A7743 (RZ/G1M).
- The new IOT2040 8250 serial/GPIO also comes in through this

- Seriously fix the Exar 8250 GPIO portions to work.
- The MCP23S08 was moved out to a pin control driver.
- Convert MEVEBU to use regmap for register access.
- Drop Vulcan support from the Broadcom driver.

Merge tag 'gpio-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.13 series.
Some administrativa:
I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
driver coming in through this tree, along with a whole bunch of Exar
8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
where they are ACKed by Andy Shevchenko.
Speaking about drivers/platform/* there is also a bunch of ACPI stuff
coming through that route, again ACKed by Andy.
The MCP23S08 changes are coming in here as well. You already have the
commits in your tree, so this is just a result of sharing an immutable
branch between pin control and GPIO.
Core:
- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO
line may loose its state during suspend/resume of the system to
save power. This is used in the Wolfson Micro Arizona driver.
- ACPI-based GPIO was tightened up a lot around the edges.
- Use bitmap_fill() to speed up a loop.
New drivers:
- Exar XRA1403 SPI-based GPIO.
- MVEBU driver now supports Armada 7K and 8K.
- LP87565 PMIC GPIO.
- Renesas R-CAR R8A7743 (RZ/G1M).
- The new IOT2040 8250 serial/GPIO also comes in through this
changeset.
Substantial driver changes:
- Seriously fix the Exar 8250 GPIO portions to work.
- The MCP23S08 was moved out to a pin control driver.
- Convert MEVEBU to use regmap for register access.
- Drop Vulcan support from the Broadcom driver.
- Serious cleanup and improvement of the mockup driver, giving us a
better test coverage.
Misc:
- Lots of janitorial clean up.
- A bunch of documentation fixes"

* Introduce the _flushcache() family of memory copy helpers and use them
for persistent memory write operations on x86. The _flushcache()
semantic indicates that the cache is either bypassed for the copy
operation (movnt) or any lines dirtied by the copy operation are
written back (clwb, clflushopt, or clflush).
* Extend dax_operations with ->copy_from_iter() and ->flush()
operations. These operations and other infrastructure updates allow
all persistent memory specific dax functionality to be pushed into
libnvdimm and the pmem driver directly. It also allows dax-specific
sysfs attributes to be linked to a host device, for example:
/sys/block/pmem0/dax/write_cache
* Add support for the new NVDIMM platform/firmware mechanisms introduced
in ACPI 6.2 and UEFI 2.7. This support includes the v1.2 namespace
label format, extensions to the address-range-scrub command set, new
error injection commands, and a new BTT (block-translation-table)
layout. These updates support inter-OS and pre-OS compatibility.
* Fix a longstanding memory corruption bug in nfit_test.
* Make the pmem and nvdimm-region 'badblocks' sysfs files poll(2)
capable.
* Miscellaneous fixes and small updates across libnvdimm and the nfit

into common helpers.
This pull request contains:
- removal of the DMA_ERROR_CODE macro, replacing it with calls
to ->mapping_error so that the dma_map_ops instances are
more self contained and can be shared across architectures (me)
- removal of the ->set_dma_mask method, which duplicates the
->dma_capable one in terms of functionality, but requires more
duplicate code.
- various updates for the coherent dma pool and related arm code

The Gemini RTC is actually a generic IP block from Faraday
Technology names FTRTC010. Rename the driver file and all
symbols to match this IP name.
The relationship can be clearly seen in the U-Boot driver
posted by Po-Yu Chuang for the Faraday A320 board:
https://lists.denx.de/pipermail/u-boot/2009-September/061326.html
Remove the dependency on ARCH_GEMINI but select the driver
for ARCH_GEMINI so we get a smooth transition. The IP block
is synthsized on different silicon and architectures.

Core:
- The documentation is moved over to RST.
- We now have agreed bindings for enabling input and output
buffers without actually enabling input and/or output on a
pin. We are chiseling out some details of pin control
electronics.
New drivers:
- ZTE ZX
- Renesas RZA1
- MIPS Ingenic JZ47xx: also switch over existing drivers in the
tree to use this pin controller and consolidate earlier
spread out code.
- Microschip MCP23S08: this driver is migrated from the GPIO
subsystem and totally rewritten to use proper pin control.
All users are switched over.
New subdrivers:
- Renesas R8A7743 and R8A7745.
- Allwinner Sunxi A83T R_PIO.
- Marvell MVEBU Armada CP110 and AP806.
- Intel Cannon Lake PCH.
- Qualcomm IPQ8074.
Notable improvements:
- IRQ support on the Marvell MVEBU Armada 37xx.
- Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM.
- Rockchip driver now supports iomux-route switching for
RK3228, RK3328 and RK3399.
- Rockchip A10 and A20 are merged into a single driver.
- STM32 has improved GPIO support.
- Samsung Exynos drivers are split per ARMv7 and ARMv8.
- Marvell MVEBU is converted to use regmap for register
access.
Maintenance:
- Several Renesas SH-PFC refactorings and updates.
- Serious code size cut for Mediatek MT7623.
- Misc janitorial and MAINTAINERS fixes.
