Pull more power management updates from Rafael Wysocki:
"These remove a questionable heuristic from the menu cpuidle governor,
fix a recent build regression in the intel_pstate driver, clean up ARM
big-Little support in cpufreq and fix up hung task watchdog's
interaction with system-wide power management transitions.
Specifics:
- Fix build regression in the intel_pstate driver that doesn't build
without CONFIG_ACPI after recent changes (Dominik Brodowski).
- One of the heuristics in the menu cpuidle governor is based on a
function returning 0 most of the time, so drop it and clean up the
scheduler code related to it (Daniel Lezcano).
- Prevent the arm_big_little cpufreq driver from being used on ARM64
which is not suitable for it and drop the arm_big_little_dt driver
that is not used any more (Sudeep Holla).
- Prevent the hung task watchdog from triggering during resume from
system-wide sleep states by disabling it before freezing tasks and
enabling it again after they have been thawed (Vitaly Kuznetsov)"

Pull ARM SoC driver updates from Arnd Bergmann:
"The most noteworthy SoC driver changes this time include:
- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.
- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.
- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl"
interface that was a little controversial at first, but the version
we merged solved that by not exposing arbitrary firmware calls to
user space.
- The Amlogic Meson platform gains a "canvas" driver that is used for
video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for their
respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in
particular a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem" device
driver.
- Some cleanups for the TI OMAP series related to their sysc
controller.
Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms"

success and non-NULL pm pointer in their struct device_driver in order
to have runtime PM happening. This has changed since following commits:

543f2503a956 ("PM / platform_bus: Allow runtime PM by default")

The current IRQ handler clears all the IRQ status bits when it bails
out. This is dangerous because it might clear away the status bits
that have just been set while processing the current handler. If this
happens, the IRQ event for the latest transfer is lost forever.
The IRQ status bits must be cleared *before* the next transfer is
kicked.

Currently, a timeout error could happen at a repeated START condition.
For a (non-repeated) START condition, the controller starts sending
data when the UNIPHIER_FI2C_CR_STA bit is set. However, for a repeated
START condition, the hardware starts running when the slave address is
written to the TX FIFO - the write to the UNIPHIER_FI2C_CR register is
actually unneeded.
Because the hardware is already running before the IRQ is enabled for
a repeated START, the driver may miss the IRQ event. In most cases,
this problem does not show up since modern CPUs are much faster than
the I2C transfer. However, it is still possible that a context switch
happens after the controller starts, but before the IRQ register is
set up.
To fix this,
- Do not write UNIPHIER_FI2C_CR for repeated START conditions.
- Enable IRQ *before* writing the slave address to the TX FIFO.
- Disable IRQ for the current CPU while queuing up the TX FIFO;
If the CPU is interrupted by some task, the interrupt handler
might be invoked due to the empty TX FIFO before completing the
setup.

This is unlikely to happen, but it is possible for a CPU to enter
the interrupt handler just after wait_for_completion_timeout() has
expired. If this happens, the hardware is accessed from multiple
contexts concurrently.
Disable the IRQ after wait_for_completion_timeout(), and do nothing
from the handler when the IRQ is disabled.

i2c/for-4.20-fixed
|

Commit 1ff2e1a44e02 ("HID: input: Create a utility class for counting
scroll events") created the helper function
hid_scroll_counter_handle_scroll()
to handle high-res scroll events and also expose them as regular wheel
events.
But the resulting algorithm was unstable, and causes scrolling to be
very unreliable. When you hit the half-way mark of the highres
multiplier, small highres movements will incorrectly translate into big
traditional wheel movements, causing odd jitters.
Simplify the code and make the output stable.
NOTE! I'm pretty sure this will need further tweaking. But this at
least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into
a usable one.

Pull C-SKY architecture port from Guo Ren:
"This contains the Linux port for C-SKY(csky) based on linux-4.19
Release, which has been through 10 rounds of review on mailing list.
More information:
http://en.c-sky.com
The development repo:
https://github.com/c-sky/csky-linux
ABI Documentation:
https://github.com/c-sky/csky-doc
Here is the pre-built cross compiler for fast test from our CI:
https://gitlab.com/c-sky/buildroot/-/jobs/101608095/artifacts/file/output/images/csky_toolchain_qemu_csky_ck807f_4.18_glibc_defconfig_482b221e52908be1c9b2ccb444255e1562bb7025.tar.xz
We use buildroot as our CI-test enviornment. "LTP, Lmbench ..." will
be tested for every commit. See here for more details:
https://gitlab.com/c-sky/buildroot/pipelines
We'll continouslly improve csky subsystem in future"
Arnd acks, and adds the following notes:
"I did a thorough review of the ABI, which as usual mainly consists of
spotting any files that don't use the asm-generic ABI itself, and
having it changed to it matches exactly what we do on other new
architectures.
I also looked at every other patch and commented on maybe half of them
where I saw something that did not quite seem right. Others have
reviewed specific patches in greater depth. I'm sure that one could
fine more of the minor details, but as long as they are not ABI
relevant, they can be fixed later.
The only patch that is part of the ABI and that nobody reviewed is the
signal handling. This is one of the areas I never worked on in much
detail. I did not see anything wrong with it, but I also don't know
what the problems with the other architectures are here, and we seem
to be hitting issues occasionally, and we never managed to generalize
this enough for new architectures to have a trivial implementation.
I was originally hoping that we could have the 64-bit time_t
interfaces ready in time to completely drop the 32-bit ones, but that
did not happen. We might still remove them in the next merge window
depending on whether the libc upstream people prefer to keep them or
not.
One more general comment: I think this may well be the last new CPU
architecture we ever add to the kernel. Both nds32 and c-sky are made
by companies that also work on risc-v, and generally speaking risc-v
seems to be killing off any of the minor licensable instruction set
projects, just like ARM has mostly killed off the custom
vendor-specific instruction sets already.
If we add another architecture in the future, it may instead be
something like the LLVM bitcode or WebAssembly, who knows?"
To which Geert Uytterhoeven pipes in about another architecture still in
the pipeline: Kalray MPPA.

Currently, the kernel doesn't let the administrator set a macsec device
up unless its lower device is currently up. This is inconsistent, as a
macsec device that is up won't automatically go down when its lower
device goes down.
Now that linkstate propagation works, there's really no reason for this
limitation, so let's remove it.

Like all other virtual devices (macvlan, vlan), the operstate of a
macsec device should match the state of its lower device. This is done
by calling netif_stacked_transfer_operstate from its netdevice notifier.
We also need to call netif_stacked_transfer_operstate when a new macsec
device is created, so that its operstate is set properly. This is only
relevant when we try to bring the device up directly when we create it.
Radu Rendec proposed a similar patch, inspired from the 802.1q driver,
that included changing the administrative state of the macsec device,
instead of just the operstate. This version is similar to what the
macvlan driver does, and updates only the operstate.

Building with -Wformat-nonliteral, gcc complains
drivers/ptp/ptp_clock.c: In function ‘ptp_clock_register’:
drivers/ptp/ptp_clock.c:239:26: warning: format not a string literal and no format arguments [-Wformat-nonliteral]
worker_name : info->name);
kthread_create_worker takes fmt+varargs to set the name of the
worker, and that happens with a vsnprintf() to a stack buffer (that is
then copied into task_comm). So there's no reason not to just pass
"ptp%d", ptp->index to kthread_create_worker() and avoid the
intermediate worker_name variable.

Pull XArray conversion from Matthew Wilcox:
"The XArray provides an improved interface to the radix tree data
structure, providing locking as part of the API, specifying GFP flags
at allocation time, eliminating preloading, less re-walking the tree,
more efficient iterations and not exposing RCU-protected pointers to
its users.
This patch set
1. Introduces the XArray implementation
2. Converts the pagecache to use it
3. Converts memremap to use it
The page cache is the most complex and important user of the radix
tree, so converting it was most important. Converting the memremap
code removes the only other user of the multiorder code, which allows
us to remove the radix tree code that supported it.
I have 40+ followup patches to convert many other users of the radix
tree over to the XArray, but I'd like to get this part in first. The
other conversions haven't been in linux-next and aren't suitable for
applying yet, but you can see them in the xarray-conv branch if you're
interested"

.. even when that "default y" is hidden syntactically as a
default !EXPERT
it's wrong.
The only reason something should be 'default y' is if it used to be
built-in, and it was made configurable, and the 'default y' is just
retaining the status quo.
Altheratively, the hardware for the driver has become _so_ common that
it really makes sense for everybody to build it. Finally, one possible
reason for 'default y' is because the option is not enabling any new
code at all, but is just enabling other options (the networking people
do this for vendor options, for example, so that you can disable whole
vendors at a time).
Clearly, none of these cases hold for the BigBen Interactive Kids'
gamepad, and HID_BIGBEN_FF should thus most definitely not default
to on for everybody.

Commit 9ee3e06610fd ("HID: i2c-hid: override HID descriptors for certain
devices") added a new dmi_system_id quirk table to override certain HID
report descriptors for some systems that lack them.
But the table wasn't properly terminated, causing the dmi matching to
walk off into la-la-land, and starting to treat random data as dmi
descriptor pointers, causing boot-time oopses if you were at all
unlucky.
Terminate the array.
We really should have some way to just statically check that arrays that
should be terminated by an empty entry actually are so. But the HID
people really should have caught this themselves, rather than have me
deal with an oops during the merge window. Tssk, tssk.

The vmstat NR_KERNEL_MISC_RECLAIMABLE counter is for kernel non-slab
allocations that can be reclaimed via shrinker. In /proc/meminfo, we can
show the sum of all reclaimable kernel allocations (including slab) as
"KReclaimable". Add the same counter also to per-node meminfo under /sys
With this counter, users will have more complete information about kernel
memory usage. Non-slab reclaimable pages (currently just the ION
allocator) will not be missing from /proc/meminfo, making users wonder
where part of their memory went. More precisely, they already appear in
MemAvailable, but without the new counter, it's not obvious why the value
in MemAvailable doesn't fully correspond with the sum of other counters
participating in it.

The vmstat counter NR_INDIRECTLY_RECLAIMABLE_BYTES was introduced by
commit eb59254608bc ("mm: introduce NR_INDIRECTLY_RECLAIMABLE_BYTES") with
the goal of accounting objects that can be reclaimed, but cannot be
allocated via a SLAB_RECLAIM_ACCOUNT cache. This is now possible via
kmalloc() with __GFP_RECLAIMABLE flag, and the dcache external names user
is converted.
The counter is however still useful for accounting direct page allocations
(i.e. not slab) with a shrinker, such as the ION page pool. So keep it,
and:
- change granularity to pages to be more like other counters; sub-page
allocations should be able to use kmalloc
- rename the counter to NR_KERNEL_MISC_RECLAIMABLE
- expose the counter again in vmstat as "nr_kernel_misc_reclaimable"; we can
again remove the check for not printing "hidden" counters

Memory region size is rounded down to page boundary and with sub-page
region it becomes 0 and there is no point to add an empty region.
Moreover, when the base is less than PAGE_SIZE we get a bogus size as
(base + size - 1) evaluates to -1.
8cccffc52694 ("of: check for size < 0 after rounding in
early_init_dt_add_memory_arch") introduced a test for wrap around for the
case when base is not page aligned, the same test can be used to ignore
sub-page region sizes.

"Notable changes:
- A large series to rewrite our SLB miss handling, replacing a lot of

- Following on from that, we now maintain a cache of SLB entries for

speedup for our context switch benchmark on Power9.
- Improvements to our handling of SLB multi-hit errors. We now print
more debug information when they occur, and try to continue running
by flushing the SLB and reloading, rather than treating them as
fatal.
- Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
- Add support for physical memory up to 2PB in the linear mapping on
64-bit Book3S. We only support up to 512TB as regular system
memory, otherwise the percpu allocator runs out of vmalloc space.
- Add stack protector support for 32 and 64-bit, with a per-task
canary.
- Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
- Support recognising "big cores" on Power9, where two SMT4 cores are
presented to us as a single SMT8 core.
- A large series to cleanup some of our ioremap handling and PTE
flags.
- Add a driver for the PAPR SCM (storage class memory) interface,
allowing guests to operate on SCM devices (acked by Dan).
- Changes to our ftrace code to handle very large kernels, where we
need to use a trampoline to get to ftrace_caller().
And many other smaller enhancements and cleanups.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- The biggest change this cycle is to remove support for the legacy IO
path (.request_fn) from request-based DM.
Jens has already started preparing for complete removal of the legacy
IO path in 4.21 but this earlier removal of support from DM has been
coordinated with Jens (as evidenced by the commit being attributed to
him).
Making request-based DM exclussively blk-mq only cleans up that
portion of DM core quite nicely.
- Convert the thinp and zoned targets over to using refcount_t where
applicable.
- A couple fixes to the DM zoned target for refcounting and other races
buried in the implementation of metadata block creation and use.
- Small cleanups to remove redundant unlikely() around a couple
WARN_ON_ONCE().
- Simplify how dm-ioctl copies from userspace, eliminating some
potential for a malicious user trying to change the executed ioctl
after its processing has begun.
- Tweaked DM crypt target to use the DM device name when naming the
various workqueues created for a particular DM crypt device (makes
the N workqueues for a DM crypt device more easily understood and
enhances user's accounting capabilities at a glance via "ps")
- Small fixup to remove dead branch in DM writecache's memory_entry().
* tag 'for-4.20/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm writecache: remove disabled code in memory_entry()

dm raid: avoid bitmap with raid4/5/6 journal device
dm crypt: make workqueue names device-specific

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

Commit 45d4c6de4e49 ("leds: gpio: Try to lookup gpiod from device")
removed the common code path that set the led_dat->gpiod pointer in
create_gpio_led(), but only added it back for the devices that have
a valid gpio_led_platform_data structure. Calling gpio_leds_create()
in gpio_led_probe() is not enough to get a valid gpiod pointer.
Fortunately enough, gpio_leds_create() already gets the needed pointer,
we just need to assign it to the relevant gpio_led_data structure.
Fixes: 45d4c6de4e49 ("leds: gpio: Try to lookup gpiod from device")
