This KUnit update for Linux 5.13-rc1 consists of several fixes and
new feature to support failure from dynamic analysis tools such as
UBSAN and fake ops for testing.
- a fake ops struct for testing a "free" function to complain if it
was called with an invalid argument, or caught a double-free. Most
return void and have no normal means of signalling failure
(e.g. super_operations, iommu_ops, etc.).

- Stop synchronizing kernel log buffer readers by logbuf_lock. As a
result, the access to the buffer is fully lockless now.
Note that printk() itself still uses locks because it tries to flush
the messages to the console immediately. Also the per-CPU temporary
buffers are still there because they prevent infinite recursion and
serialize backtraces from NMI. All this is going to change in the
future.
- kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
removal.

Merge tag 'netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull network filesystem helper library updates from David Howells:
"Here's a set of patches for 5.13 to begin the process of overhauling
the local caching API for network filesystems. This set consists of
two parts:
(1) Add a helper library to handle the new VM readahead interface.
This is intended to be used unconditionally by the filesystem
(whether or not caching is enabled) and provides a common
framework for doing caching, transparent huge pages and, in the
future, possibly fscrypt and read bandwidth maximisation. It also
allows the netfs and the cache to align, expand and slice up a
read request from the VM in various ways; the netfs need only
provide a function to read a stretch of data to the pagecache and
the helper takes care of the rest.
(2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
facility to do async DIO to transfer data to/from the netfs's
pages, rather than using readpage with wait queue snooping on one
side and vfs_write() on the other. It also uses less memory, since
it doesn't do buffered I/O on the backing file.
Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
available to be read from the cache. Whilst this is an improvement
from the bmap interface, it still has a problem with regard to a
modern extent-based filesystem inserting or removing bridging
blocks of zeros. Fixing that requires a much greater overhaul.
This is a step towards overhauling the fscache API. The change is
opt-in on the part of the network filesystem. A netfs should not try
to mix the old and the new API because of conflicting ways of handling
pages and the PG_fscache page flag and because it would be mixing DIO
with buffered I/O. Further, the helper library can't be used with the
old API.
This does not change any of the fscache cookie handling APIs or the
way invalidation is done at this time.
In the near term, I intend to deprecate and remove the old I/O API
(fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
fscache_write_page() and fscache_uncache_page()) and eventually
replace most of fscache/cachefiles with something simpler and easier
to follow.
This patchset contains the following parts:
- Some helper patches, including provision of an ITER_XARRAY iov
iterator and a function to do readahead expansion.
- Patches to add the netfs helper library.
- A patch to add the fscache/cachefiles kiocb API.
- A pair of patches to fix some review issues in the ITER_XARRAY and
read helpers as spotted by Al and Willy.
Jeff Layton has patches to add support in Ceph for this that he
intends for this merge window. I have a set of patches to support AFS
that I will post a separate pull request for.
With this, AFS without a cache passes all expected xfstests; with a
cache, there's an extra failure, but that's also there before these
patches. Fixing that probably requires a greater overhaul. Ceph also
passes the expected tests.
I also have patches in a separate branch to tidy up the handling of
PG_fscache/PG_private_2 and their contribution to page refcounting in
the core kernel here, but I haven't included them in this set and will
route them separately"

The only core work for SPI this time around is the completion of the
conversion to the new style method for specifying transfer delays,
meaning we can cope with what most controllers support more directly
using conversions in the core rather than open coding in drivers.
Otherwise it's a good stack of cleanups and fixes plus a few new
drivers.
The conversion to new style transfer delay will cause an issue with a
newly added staging driver which has a straightforward resolution in
-next.
- Completion of the conversion to new style transfer delay
configuration.
- Introduction and use of module_parport_driver() helper, merged here
as there's no parport tree.
- Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,

The most notable change is the removal of the amd_energy driver. It was
rendered all but unusable by making its attributes privileged-only to work
around a security issue. A suggested remedy was rejected by AMD, so the
only real solution was to remove the driver. For the future, we'll have
to make sure that no privileged-access-only drivers are accepted into the
hwmon subsystem in the first place. The hwmon ABI document was updated
accordingly.
Other changes:
PMBus drivers:
- Added driver for MAX15301
- Added driver for BluTek BPA-RS600
- Added driver for fsp-3y PSUs and PDUs
- Added driver for Infineon IR36021
- Added driver for ST STPDDC60
- Added support for TI TPS53676 to tps53679 driver
- Introduced PMBUS symbol namespace
This was made necessary by a suggestion to use its exported functions
from outside the hwmon subsystem.
- Minor improvements and bug fixes
New drivers:
- Driver for NZXT Kraken X42/X52/X62/X72
Driver enhancements:
- Added support for Intel D5005 to intel-m10-bmc-hwmon driver
- Added support for NCT6686D to nct6683 driver
Other:
- Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info()
- Added support for fan drawers capability and present registers to mlxreg-fan
driver
- Added Dell Latitude E7440 to fan control whitelist in dell-smm driver
- Replaced snprintf in show functions with sysfs_emit
Done with coccinelle script for all drivers to preempt endless per-driver
submissions of the same change.
- Use kobj_to_dev()

The Nuvoton WPCM450 BMC is an older chip based on the ARM926 CPU core
that remains in use on Supermicro X9 server boards among others. Support
gets added for a particular server board using this SoC along with the
basic platform bringup.
As the platform is a predecessor to the npcm7xx platform we already
support, it is added to the same directory, despite using a different
name. It also seems to be related to the older w90x900/nuc9xx platform
that was removed last year.

There are six new SoCs added this time. Apple M1 and Nuvoton WPCM450
have separate branches because they are new SoC families that require
changes outside of device tree files. The other four are variations of
already supported chips and get merged through this branch:
- STMicroelectronics STM32H750 is one of many variants of STM32
microcontrollers based on the Cortex-M7 core. This is particularly
notable since we rarely add support for new MMU-less chips
these days. In this case, the board that gets added along with
the platform is not a SoC reference platform but the "Art Pi"
(https://art-pi.gitee.io/website/) machine that was originally design
for the RT-Thread RTOS.
- NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial
SoC family, using two Cortex-A72 and four Cortex-A53 cores. It
gets added along with its reference board, the "NXP i.MX8QuadMax
Multisensory Enablement Kit".
- Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c)
that is used in some Chromebooks and Windows laptops. Only a reference
board is added for the moment.
- TI AM64x Sita4ra is a new version of the K3 SoC family for industrial
control, motor control, remote IO, IoT gateway etc., similar to the
older AM65x family. Two reference machines are added alongside.
Among the newly added machines, there is a very clear skew towards 64-bit
machines now, with 12 32-bit machines compared to 23 64-bit machines. The
full list sorted by SoC is:
- ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board
- Allwinner A10: Topwise A721 Tablet
- Amlogic GXL: MeCool KII TV box
- Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes
- Broadcom BCM4908: TP-Link Archer C2300 V1 router
- MStar SSD202D: M5Stack UnitV2 camera
- Marvell Armada 38x: ATL-x530 ethernet switch
- Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311,
Asus Flip CM3, Asus Detachable CM3
- Mediatek MT8516/MT8183: OLogic Pumpkin Board
- NXP i.MX7: reMarkable Tablet
- NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini
- Nuvoton NPCM730: Quanta GBS BMC
- Qualcomm X55: Telit FN980 TLB SoM, Thundercomm TurboX T55 SoM
- Qualcomm MSM8998: OnePlus 5/5T phones
- Qualcomm SM8350: Snapdragon 888 Mobile Hardware Development Kit
- Rockchip RK3399: NanoPi R4S board
- STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM,
EDIMM2.2 Starter Kit, Carrier, SOM
- TI AM65: Siemens SIMATIC IOT2050 gateway
There is notable work going into extending already supported machines
and SoCs:
- ASpeed AST2500
- Allwinner A23, A83t, A31, A64, H6
- Amlogic G12B
- Broadcom BCM4908
- Marvell Armada 7K/8K/CN91xx
- Mediatek MT6589, MT7622, MT8173, MT8183, MT8195
- NXP i.MX8Q, i.MX8MM, i.MX8MP
- Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350
- Renesas R-Car M3, V3U
- Rockchip RK3328, RK3399
- STEricsson U8500
- STMicroelectronics STM32MP141
- Samsung Exynos 4412
- TI K3-AM65, K3-J7200
- TI OMAP3
Among the treewide cleanups and bug fixes, two parts stand out:
- There are a number of cleanups for issues pointed out by 'make
dtbs_check' this time, and I expect more to come in the future as we
increasingly check for regressions.
- After a change to the MMC subsystem that can lead to unpredictable
device numbers, several platforms add 'aliases' properties for these
to give each MMC controller a fixed number.

over these drivers, as well as these "larger" changes:
- thunderbolt updates and new features added
- xhci driver updates and split out of a mediatek-specific xhci
driver from the main xhci module to make it easier to work
with (something that I have been wanting for a while).
- loads of typec feature additions and updates
- dwc2 driver updates
- dwc3 driver updates
- gadget driver fixes and minor updates
- loads of usb-serial cleanups and fixes and updates
- usbip documentation updates and fixes

Here is the big set of tty and serial driver updates for 5.13-rc1.
Actually busy this release, with a number of cleanups happening:
- much needed core tty cleanups by Jiri Slaby
- removal of unused and orphaned old-style serial drivers. If
anyone shows up with this hardware, it is trivial to restore
these but we really do not think they are in use anymore.
- fixes and cleanups from Johan Hovold on a number of termios
setting corner cases that loads of drivers got wrong as well
as removing unneeded code due to tty core changes from long
ago that were never propagated out to the drivers
- loads of platform-specific serial port driver updates and
fixes
- coding style cleanups and other small fixes and updates all
over the tty/serial tree.
All of these have been in linux-next for a while now with no reported
issues.

Here is the big set of staging and IIO driver updates for 5.13-rc1.
Lots of little churn in here, and some larger churn as well. Major
things are:
- removal of wimax drivers, no one has this hardware anymore for
this failed "experiment".
- removal of the Google gasket driver, turns out no one wanted
to maintain it or cares about it anymore, so they asked for it
to be removed.
- comedi finally moves out of the staging directory into
drivers/comedi/ This is one of the oldest kernel subsystems
around, being created in the 2.0 kernel days, and was one of
the first things added to drivers/staging/ when that was
created over 15 years ago. It should have been moved out of
staging a long time ago, it's well maintained and used by
loads of different devices in the real world every day. Nice
to see this finally happen.
- so many tiny coding style cleanups it's not funny. Perfect
storm of at least 2 different intern project application
deadlines combined to provide a huge number of new
contributions in this area from people learning how to do
kernel development. Great job to everyone involved here.
There's also the normal updates for IIO drivers with new IIO drivers and
updates all over that subsystem.
All of these have been in linux-next for a while with no reported
issues.

Newer CPUs provide a second mechanism to detect operations with lock
prefix which go accross a cache line boundary. Such operations have to
take bus lock which causes a system wide performance degradation when
these operations happen frequently.
The new mechanism is not using the #AC exception. It triggers #DB and is
restricted to operations in user space. Kernel side split lock access can
only be detected by the #AC based variant. Contrary to the #AC based
mechanism the #DB based variant triggers _after_ the instruction was
executed. The mechanism is CPUID enumerated and contrary to the #AC
version which is based on the magic TEST_CTRL_MSR and model/family based
enumeration on the way to become architectural.

Pull x86 bus lock detection updates from Thomas Gleixner:
"Support for enhanced split lock detection:
Newer CPUs provide a second mechanism to detect operations with lock
prefix which go accross a cache line boundary. Such operations have to
take bus lock which causes a system wide performance degradation when
these operations happen frequently.
The new mechanism is not using the #AC exception. It triggers #DB and
is restricted to operations in user space. Kernel side split lock
access can only be detected by the #AC based variant.
Contrary to the #AC based mechanism the #DB based variant triggers
_after_ the instruction was executed. The mechanism is CPUID
enumerated and contrary to the #AC version which is based on the magic
TEST_CTRL_MSR and model/family based enumeration on the way to become
architectural"

Provide support for randomized stack offsets per syscall to make
stack-based attacks harder which rely on the deterministic stack layout.
The feature is based on the original idea of PaX's RANDSTACK feature, but
uses a significantly different implementation.
The offset does not affect the pt_regs location on the task stack as this
was agreed on to be of dubious value. The offset is applied before the
actual syscall is invoked.
The offset is stored per cpu and the randomization happens at the end of
the syscall which is less predictable than on syscall entry.
The mechanism to apply the offset is via alloca(), i.e. abusing the
dispised VLAs. This comes with the drawback that stack-clash-protection
has to be disabled for the affected compilation units and there is also
a negative interaction with stack-protector.
Those downsides are traded with the advantage that this approach does not
require any intrusive changes to the low level assembly entry code, does
not affect the unwinder and the correct stack alignment is handled
automatically by the compiler.
The feature is guarded with a static branch which avoids the overhead when
disabled.
Currently this is supported for X86 and ARM64.

Core changes:
- Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can be
cleaned up which either use a seperate mechanism to prevent auto-enable
at request time or have a racy mechanism which disables the interrupt
right after request.
- Get rid of the last usage of irq_create_identity_mapping() and remove
the interface.
- An overhaul of tasklet_disable(). Most usage sites of tasklet_disable()
are in task context and usually in cleanup, teardown code pathes.
tasklet_disable() spinwaits for a tasklet which is currently executed.
That's not only a problem for PREEMPT_RT where this can lead to a live
lock when the disabling task preempts the softirq thread. It's also
problematic in context of virtualization when the vCPU which runs the
tasklet is scheduled out and the disabling code has to spin wait until
it's scheduled back in. Though there are a few code pathes which invoke
tasklet_disable() from non-sleepable context. For these a new disable
variant which still spinwaits is provided which allows to switch
tasklet_disable() to a sleep wait mechanism. For the atomic use cases
this does not solve the live lock issue on PREEMPT_RT. That is mitigated
by blocking on the RT specific softirq lock.
- The PREEMPT_RT specific implementation of softirq processing and
local_bh_disable/enable().
On RT enabled kernels soft interrupt processing happens always in task
context and all interrupt handlers, which are not explicitly marked to
be invoked in hard interrupt context are forced into task context as
well. This allows to protect against softirq processing with a per
CPU lock, which in turn allows to make BH disabled regions preemptible.
Most of the softirq handling code is still shared. The RT/non-RT
specific differences are addressed with a set of inline functions which
provide the context specific functionality. The local_bh_disable() /
local_bh_enable() mechanism are obviously seperate.
- The usual set of small improvements and cleanups
Driver changes:
- New drivers for Nuvoton WPCM450 and DT 79rc3243x interrupt controllers
- Extended functionality for MStar, STM32 and SC7280 irq chips
- Enhanced robustness for ARM GICv3/4.1 drivers
- The usual set of cleanups and improvements all over the place

Commit 855b35ea96c4 ("usb: common: move function's kerneldoc next to its
definition") moved the USB common function documentation out of the
linux/usb/ch9.h header file into drivers/usb/common/common.c and
drivers/usb/common/debug.c, which causes the following 'make htmldocs'
build warning:
include/linux/usb/ch9.h:1: warning: no structured comments found
Fix that up by pointing the documentation at the correct location.
