dynamic_debug: consolidate DEFINE_DYNAMIC_DEBUG_METADATA definitions
Instead of defining DEFINE_DYNAMIC_DEBUG_METADATA in terms of a helper DEFINE_DYNAMIC_DEBUG_METADATA_KEY, that needs another helper dd_key_init to be properly defined, just make the various #ifdef branches define a _DPRINTK_KEY_INIT that can be used directly, similar to _DPRINTK_FLAGS_DEFAULT.

linux/device.h: use DYNAMIC_DEBUG_BRANCH in dev_dbg_ratelimited
Patch series "various dynamic_debug patches", v4. This started as an experiment to see how hard it would be to change the four pointers in struct _ddebug into relative offsets, a la CONFIG_GENERIC_BUG_RELATIVE_POINTERS, thus saving 16 bytes per pr_debug site (and thus exactly making up for the extra space used by the introduction of jump labels in 9049fc74). I stumbled on a few things that are probably worth fixing regardless of whether that goal is deemed worthwhile. Back at v3 (in November), I redid the implementation on top of the fancy new asm-macros stuff. Luckily enough, v3 didn't get picked up, since the asm-macros were backed out again. I still want to do the relative-pointers thing eventually, but we're close to the merge window opening, so here's just most of the "incidental" patches, some of which also serve as preparation for the relative pointers. This patch (of 4): dev_dbg_ratelimited tests the dynamic debug descriptor the old-fashioned way, and doesn't utilize the static key/jump label implementation when CONFIG_JUMP_LABEL is set. Use the DYNAMIC_DEBUG_BRANCH which is defined appropriately.

linux/kernel.h: split *_MAX and *_MIN macros into <linux/limits.h>
<linux/kernel.h> tends to be cluttered because we often put various sort of unrelated stuff in it. So, we have split out a sensible chunk of code into a separate header from time to time. This commit splits out the *_MAX and *_MIN defines. The standard header <limits.h> contains various MAX, MIN constants including numerial limits. [1] I think it makes sense to move in-kernel MAX, MIN constants into include/linux/limits.h. We already have include/uapi/linux/limits.h to contain some user-space constants. I changed its include guard to _UAPI_LINUX_LIMITS_H. This change has no impact to the user-space because scripts/headers_install.sh rips off the '_UAPI' prefix from the include guards of exported headers.

linux/kernel.h: use 'short' to define USHRT_MAX, SHRT_MAX, SHRT_MIN
The commit log of 44f564a4bf6a ("ipc: add definitions of USHORT_MAX and
others") did not explain why it used (s16) and (u16) instead of (short)
and (unsigned short).
Let's use (short) and (unsigned short), which is more sensible, and more
consistent with the other MAX/MIN defines.
As you see in include/uapi/asm-generic/int-ll64.h, s16/u16 are
typedef'ed as signed/unsigned short. So, this commit does not have a
functional change.
Remove the unneeded parentheses around ~0U while we are here.

lib/vsprintf.c: move sizeof(struct printf_spec) next to its definition
At the time of commit d048419311ff ("lib/vsprintf.c: expand field_width
to 24 bits"), there was no compiletime_assert/BUILD_BUG/.... variant
that could be used outside function scope. Now we have static_assert(),
so move the assertion next to the definition instead of hiding it in
some arbitrary function.
Also add the appropriate #include to avoid relying on build_bug.h being
pulled in via some arbitrary chain of includes.

build_bug.h: add wrapper for _Static_assert
BUILD_BUG_ON() is a little annoying, since it cannot be used outside function scope. So one cannot put assertions about the sizeof() a struct next to the struct definition, but has to hide that in some more or less arbitrary function. Since gcc 4.6 (which is now also the required minimum), there is support for the C11 _Static_assert in all C modes, including gnu89. So add a simple wrapper for that. _Static_assert() requires a message argument, which is usually quite redundant (and I believe that bug got fixed at least in newer C++ standards), but we can easily work around that with a little macro magic, making it optional. For example, adding static_assert(sizeof(struct printf_spec) == 8); in vsprintf.c and modifying that struct to violate it, one gets ./include/linux/build_bug.h:78:41: error: static assertion failed: "sizeof(struct printf_spec) == 8" #define __static_assert(expr, msg, ...) _Static_assert(expr, "" msg "") godbolt.org suggests that _Static_assert() has been support by clang since at least 3.0.0.

kernel/hung_task.c: Use continuously blocked time when reporting.
Since commit a2e514453861 ("kernel/hung_task.c: allow to set checking
interval separately from timeout") added hung_task_check_interval_secs,
setting a value different from hung_task_timeout_secs
echo 0 > /proc/sys/kernel/hung_task_panic
echo 120 > /proc/sys/kernel/hung_task_timeout_secs
echo 5 > /proc/sys/kernel/hung_task_check_interval_secs
causes confusing output as if the task was blocked for
hung_task_timeout_secs seconds from the previous report.
[ 399.395930] INFO: task kswapd0:75 blocked for more than 120 seconds.
[ 405.027637] INFO: task kswapd0:75 blocked for more than 120 seconds.

[ 421.932305] INFO: task kswapd0:75 blocked for more than 120 seconds.
Although we could update t->last_switch_time after sched_show_task(t) if
we want to report only every 120 seconds, reporting every 5 seconds
might not be very bad for monitoring after a problematic situation has
started. Thus, let's use continuously blocked time instead of updating
previously reported time.

The single quotation marks around "const" were causing a documentation markup warning with reST. Instead of fixing that warning, just delete that comment line and the gcc-3.3 hack of using "const" in the roundup() macro since gcc-3.3 is no longer supported for kernel builds. I did around 20 different $arch builds with no problems, but we'll just have to see if this causes problems for anyone else out there.

kernel/panic.c: taint: fix debugfs_simple_attr.cocci warnings
Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE for debugfs files. Semantic patch information: Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file() imposes some significant overhead as compared to DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe(). Generated by: scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci The _unsafe() part suggests that some of them "safeness responsibilities" are now panic.c responsibilities. The patch is OK since panic's clear_warn_once_fops struct file_operations is safe against removal, so we don't have to use otherwise necessary debugfs_file_get()/debugfs_file_put().

Staging/IIO patches for 5.1-rc1
Here is the big staging/iio driver pull request for 5.1-rc1. Lots of good IIO driver updates and cleanups in here as always. Combined with the removal of the xgifb driver, we have a net "loss" of over 9000 lines in the pull request, always a nice thing.

iio: adc: fix warning in Qualcomm PM8xxx HK/XOADC driver
The pm8xxx_get_channel() implementation is unclear, and causes gcc to
suddenly generate odd warnings. The trigger for the warning (at least
for me) was the entirely unrelated commit 79a4e91d1bb2 ("device.h: Add
__cold to dev_<level> logging functions"), which apparently changes gcc
code generation in the caller function enough to cause this:
drivers/iio/adc/qcom-pm8xxx-xoadc.c: In function ‘pm8xxx_xoadc_probe’:
drivers/iio/adc/qcom-pm8xxx-xoadc.c:633:8: warning: ‘ch’ may be used uninitialized in this function [-Wmaybe-uninitialized]
ret = pm8xxx_read_channel_rsv(adc, ch, AMUX_RSV4,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
&read_nomux_rsv4, true);
~~~~~~~~~~~~~~~~~~~~~~~
drivers/iio/adc/qcom-pm8xxx-xoadc.c:426:27: note: ‘ch’ was declared here
struct pm8xxx_chan_info *ch;
^~
because gcc for some reason then isn't able to see that the termination
condition for the "for( )" loop in that function is also the condition
for returning NULL.
So it's not _actually_ uninitialized, but the function is admittedly
just unnecessarily oddly written.
Simplify and clarify the function, making gcc also see that it always
returns a valid initialized value.

Driver core patches for 5.1-rc1
Here is the big driver core patchset for 5.1-rc1 More patches than "normal" here this merge window, due to some work in the driver core by Alexander Duyck to rework the async probe functionality to work better for a number of devices, and independant work from Rafael for the device link functionality to make it work "correctly". Also in here is: - lots of BUS_ATTR() removals, the macro is about to go away - firmware test fixups - ihex fixups and simplification - component additions (also includes i915 patches) - lots of minor coding style fixups and cleanups.

Char/Misc driver patches for 5.1-rc1
Here is the big char/misc driver patch pull request for 5.1-rc1. The largest thing by far is the new habanalabs driver for their AI accelerator chip. For now it is in the drivers/misc directory but will probably move to a new directory soon along with other drivers of this type. Other than that, just the usual set of individual driver updates and fixes. There's an "odd" merge in here from the DRM tree that they asked me to do as the MEI driver is starting to interact with the i915 driver, and it needed some coordination. All of those patches have been properly acked by the relevant subsystem maintainers. All of these have been in linux-next with no reported issues, most for quite some time.

- Kill NULL device object in memory allocations
- Lots of procfs API cleanups
ASoC core:
- Support for only powering up channels that are actively being used
- Cleanups / fixes of topology API
ASoC drivers:
- MediaTek BTCVSD for a Bluetooth radio chip, which is the first such
driver we've had upstream!
- Quite a few improvements to simplify the generic card drivers,
especially the merge of the SCU cards into the main generic drivers
- Lots of fixes for probing on Intel systems to follow more standard
styles
- A big refresh and cleanup of the Samsung drivers
- New drivers: Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341
and CS35L26, Google ChromeOS embedded controllers, Ingenic JZ4725B,
MediaTek BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328,
Spreadtrum DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM
formatters
ALSA drivers:
- Improvements of Tegra HD-audio controller driver for supporting new
chips
- HD-audio codec quirks for ALC294 S4 resume, ASUS laptop, Chrome
headset button support and Dell workstations
- Improved DSD support on USB-audio
- Quirk for MOTU MicroBook II USB-audio

ARM: SoC: late updates for linux-5.1
Here are two branches that came relatively late during the linux-5.0
development cycle and have dependencies on the other branches:
- On the TI OMAP platform, the CPSW Ethernet PHY mode selection driver
is being replaced, this puts the final pieces in place
- On the DaVinci platform, the interrupt handling code in arch/arm
gets moved into a regular device driver in drivers/irqchip.
Since they both had some time in linux-next after the 5.0-rc8
release, I'm sending them along with the other updates.

ARM: New SoC family support
Two new SoC families are added this time. Sugaya Taichi submitted support for the Milbeaut SoC family from Socionext and explains: "SC2000 is a SoC of the Milbeaut series. equipped with a DSP optimized for computer vision. It also features advanced functionalities such as 360-degree, real-time spherical stitching with multi cameras, image stabilization for without mechanical gimbals, and rolling shutter correction. More detail is below: https://www.socionext.com/en/products/assp/milbeaut/SC2000.html" Interestingly, this one has a history dating back to older chips made by Socionext and previously Matsushita/Panasonic based on their own mn10300 CPU architecture that was removed from the kernel last year. Manivannan Sadhasivam adds support for another SoC family, this is the Bitmain BM1880 chip used in the Sophon Edge TPU developer board. The chip is intended for Deep Learning applications, and comes with dual-core Arm Cortex-A53 to run Linux as well as a RISC-V microcontroller core to control the tensor unit. For the moment, the TPU is not accessible in mainline Linux, so we treat it as a generic Arm SoC.

ARM: SoC driver updates for 5.1
As usual, the drivers/tee and drivers/reset subsystems get merged here, with the expected set of smaller updates and some new hardware support.

ARM: SoC device tree updates for 5.1
This is a smaller update than the past few times, but with just over
500 non-merge changesets still dwarfes the rest of the SoC tree.
Three new SoC platforms get added, each one a follow-up to an existing
product, and added here in combination with a reference platform:
- Renesas RZ/A2M (R7S9210) 32-bit Cortex-A9 Real-time imaging processor
https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rza/rza2m.html
- Renesas RZ/G2E (r8a774c0) 64-bit Cortex-A53 SoC "for
Rich Graphics Applications".
https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rzg/rzg2e.html
- NXP i.MX8QuadXPlus 64-bit Cortex-A35 SoC
https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-8-processors/i.mx-8x-family-arm-cortex-a35-3d-graphics-4k-video-dsp-error-correcting-code-on-ddr:i.MX8X
These are actual commercial products we now support with an in-kernel
device tree source file:
- Bosch Guardian is a product made by Bosch Power
Tools GmbH, based on the Texas Instruments AM335x chip
- Winterland IceBoard is a Texas Instruments AM3874 based
machine used in telescopes at the south pole and elsewhere, see commit
d031773169df2 for some pointers:
- Inspur on5263m5 is an x86 server platform with an Aspeed
ast2500 baseboard management controller. This is for running on
the BMC.
- Zodiac Digital Tapping Unit, apparently a kind of ethernet
switch used in airplanes.
- Phicomm K3 is a WiFi router based on Broadcom bcm47094
- Methode Electronics uDPU FTTdp distribution point unit
- X96 Max, a generic TV box based on Amlogic G12a (S905X2)
- NVIDIA Shield TV (Darcy) based on Tegra210
And then there are several new SBC, evaluation, development or modular
systems that we add:
- Three new Rockchips rk3399 based boards:
- FriendlyElec NanoPC-T4 and NanoPi M4
- Radxa ROCK Pi 4
- Five new i.MX6 family SoM modules and boards for industrial
products:
- Logic PD i.MX6QD SoM and evaluation baseboad
- Y Soft IOTA Draco/Hydra/Ursa family boards based on i.MX6DL
- Phytec phyCORE i.MX6 UltraLite SoM and evaluation module
- MYIR Tech MYD-LPC4357 development based on the NXP lpc4357
microcontroller
- Chameleon96, an Intel/Altera Cyclone5 based FPGA development
system in 96boards form factor
- Arm Fixed Virtual Platforms(FVP) Base RevC, a purely
virtual platform for corresponding to the latest "fast model"
- Another Raspberry Pi variant: Model 3 A+, supported both
in 32-bit and 64-bit mode.
- Oxalis Evalkit V100 based on NXP Layerscape LS1012a,
in 96Boards enterprise form factor
- Elgin RV1108 R1 development board based on 32-bit Rockchips RV1108
For already supported boards and SoCs, we often add support for new
devices after merging the drivers. This time, the largest changes include
updates for
- STMicroelectronics stm32mp1, which was now formally
launched last week
- Qualcomm Snapdragon 845, a high-end phone and low-end laptop chip
- Action Semi S700
- TI AM654x, their recently merged 64-bit SoC from the OMAP family
- Various Amlogic Meson SoCs
- Mediatek MT2712
- NVIDIA Tegra186 and Tegra210
- The ancient NXP lpc32xx family
- Samsung s5pv210, used in some older mobile phones
Many other chips see smaller updates and bugfixes beyond that.

ARM: SoC platform updates for 5.1
The APM X-Gene platform is now maintained by folks from Ampere computing that took over the product line a while ago, this gets reflected in the MAINTAINERS file. Cleanups continue on the older mach-davinci and mach-pxa platform, to get them to be more like the modern ones. For pxa, we now remove the Raumfeld platform code as it now works with device tree based booting. i.MX adds a couple new features for the i.MX7ULP SoC Mediatek gains support for a new SoC: MT7629 is a new wireless router platform, following MT7623. Aside from those, there are the usual minor cleanups and bugfixes across several platforms.

Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar:
"The biggest part of this tree is the new auto-generated atomics API
wrappers by Mark Rutland.
The primary motivation was to allow instrumentation without uglifying
the primary source code.
The linecount increase comes from adding the auto-generated files to
the Git space as well:
include/asm-generic/atomic-instrumented.h | 1689 ++++++++++++++++--
include/asm-generic/atomic-long.h | 1174 ++++++++++---
include/linux/atomic-fallback.h | 2295 +++++++++++++++++++++++++
include/linux/atomic.h | 1241 +------------
I preferred this approach, so that the full call stack of the (already
complex) locking APIs is still fully visible in 'git grep'.
But if this is excessive we could certainly hide them.
There's a separate build-time mechanism to determine whether the
headers are out of date (they should never be stale if we do our job
right).
Anyway, nothing from this should be visible to regular kernel
developers.
Other changes:
- Add support for dynamic keys, which removes a source of false
positives in the workqueue code, among other things (Bart Van
Assche)
- Updates to tools/memory-model (Andrea Parri, Paul E. McKenney)
- qspinlock, wake_q and lockdep micro-optimizations (Waiman Long)
- misc other updates and enhancements"
