Pull ARM DT updates from Arnd Bergmann:
"This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit
respectively. There are lots of cleanups and additional hardware
support for platforms we already support based on SoCs from Renesas,
ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and
other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
- The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone
platform, usually paired with an external 5G modem. So far we only
support the Qualcomm SM8150 MTP reference platform, but no actual
products.
- For the slightly older Qualcomm platforms, support for several
interesting products is getting added: Three laptops based on
Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix
630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630)
and several phones based on the older Snapdragon 410/MSM8916
(Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed"
aka Wileyfox Swift).
- Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
- Allwinner V3 is a repackaged version of the existing low-end V3s
chip, and is used in the tiny Lichee Pi Zero plus, also added here.
There is also a new TV set-top box based on Allwinner H6, the Tanix
TX6, and the eMMC variant of the Olimex A64-Olinuxino development
board.
- NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC
family, similar to the i.MX8M Mini. As usual, there is a large
number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML,
SolidRun Hummingboard Pulse baseboard and System-on-Module,
Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion
PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the
Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
- In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
- Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from
their set-top-box line and smart speaker with newer CPU and GPU
cores compared to their predecessors. Both are now also supported
by the Khadas VIM3 development board series, and the dts files for
that get reorganized a bit to better deal with all variants.
Another board based on SM1 that gets added is the SEI Robotics
SEI610.
- There are a handful of new x86 and Power9 server boards using
Aspeed BMC chips that are gaining support for running Linux on the
BMC through the OpenBMC project: Facebook
Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably
these are still new machines using SoCs based on the ARM9 and ARM11
CPU cores, as support for the new Cortex-A7 based AST2600 is still
ramping up.
- There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the
low-end RK3229 chip, while the two AOpen products Chromebox Mini
(Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for
commercial settings(digital signage, PoS, ...).
- One more single-board computer based on the popular 64-bit RK3399
is added: the Leez RK3399 P710"

Pull ARM SoC platform updates from Arnd Bergmann:
"The main change this time around is a cleanup of some of the oldest
platforms based on the XScale and ARM9 CPU cores, which are between 10
and 20 years old.
The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
IOP33x/IOP13xx platforms are removed after we determined that nobody
is using them any more.
The TI Davinci and NXP LPC32xx platforms on the other hand are still
in active use and are converted to the ARCH_MULTIPLATFORM build,
meaning that we can compile a kernel that works on these along with
most other ARMv5 platforms. Changes toward that goal are also merged
for IOP32x, but additional work is needed to complete this. Patches
for the remaining ARMv5 platforms have started but need more work and
some testing.
Support for the new ASpeed AST2600 gets added, this is based on the
Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
ARMv6 chips in the same family.
Other changes include a cleanup of the ST-Ericsson ux500 platform and
the move of the TI Davinci platform to a new clocksource driver"
[ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
buildable on other platforms through COMPILE_TEST, but that causes new
warnings that I most definitely do not want to see during the merge
window as that could hide other issues.
So the COMPILE_TEST option got disabled for them again - Linus ]

Pull arm64 updates from Will Deacon:
"Although there isn't tonnes of code in terms of line count, there are
a fair few headline features which I've noted both in the tag and also
in the merge commits when I pulled everything together.
The part I'm most pleased with is that we had 35 contributors this
time around, which feels like a big jump from the usual small group of
core arm64 arch developers. Hopefully they all enjoyed it so much that
they'll continue to contribute, but we'll see.
It's probably worth highlighting that we've pulled in a branch from
the risc-v folks which moves our CPU topology code out to where it can
be shared with others.
Summary:
- 52-bit virtual addressing in the kernel
- New ABI to allow tagged user pointers to be dereferenced by
syscalls
- Early RNG seeding by the bootloader
- Improve robustness of SMP boot
- Fix TLB invalidation in light of recent architectural
clarifications
- Support for i.MX8 DDR PMU
- Remove direct LSE instruction patching in favour of static keys
- Function error injection using kprobes
- Support for the PPTT "thread" flag introduced by ACPI 6.3

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of changes in the GPIO subsystem for the v5.4 kernel
cycle.
Core changes:
- Support hierarchical GPIO irqchips.
We now have three consumers that can use this: Intel IXP4xx,
ThunderX and Qualcomm SPMI GPIO (in the pinctrl subsystem).
The support code has been long in the making and hashed out so it
should be easily adaptable for all hierarchical irqchip parents.
The code only gets compiled in if hierarchical irqchip is used at
the topmost irq controller at least, as the hierarchical irqchip
requires strict hierarchy all the way up in the system.
- Determine the need for a "valid_mask" for GPIO lines on the
gpio_chip and conversely for the "valid_mask" for the GPIO
interrupt chip interrupt lines by looking for a .init_valid_mask()
callback in the main chip or GPIO interrupt chip respectively.
Allocate it with bitmap_alloc().
- Isolate the device tree/open firmware GPIO description code out in
its own file properly.
- Isolate the ACPI GPIO description code out in its own file
properly.
- Drop a whole lot of #ifdef:s in the main includes: it does not hurt
to keep the include items around, and we get quicker and clearer
compile failures if the appropriate kernel symbols are not selected
for drivers.
New/deleted drivers:
- New driver for Aspeed SGPIO.
- The KS8695 driver is deleted as the platform gets deleted from
arch/arm in this kernel cycle.
- The Cirrus Logic Madera driver now supports CS47L92 and CS47L15.
- The Freescale MPC8xxx now supports LS1028A and LS1088A.
Driver improvements:
- We pass the GPIO irqchip intialization by directly filling in the
struct instead of using set-up functions (the new way) for Intel
MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86,
MT7621, Zynq and EP93xx.
Out-of-band changes:

a new adition to the userspace projects that make use of the pidfd
api. The qt project was nice enough to send a mail pointing out that
they have a pr up to switch to the pidfd api (cf. [2]).
Second, this tag contains an extension to the waitid() syscall to make
it possible to wait on the current process group in a race free manner
(even though the actual problem is very unlikely) by specifing 0
together with the P_PGID type. This extension traces back to a
discussion on the glibc development mailing list.
There are also a range of tests for the features above. Additionally,
the test-suite which detected the pidfd-polling race we fixed in [3]
is included in this tag"

The module load should fail only if there is something wrong with the
configuration or if an error prevents it to work properly. The module
should be able to be loaded with (nr_device == 0), since it will not
trigger errors or be in malfunction state. Preventing loading with zero
devices also breaks applications that configures this module using
configfs API. Remove the nr_device check to fix this.

Currently rq->data_len will be decreased by partial completion or
zeroed by completion, so when blk_stat_add() is invoked, data_len
will be zero and there will never be samples in poll_cb because
blk_mq_poll_stats_bkt() will return -1 if data_len is zero.
We could move blk_stat_add() back to __blk_mq_complete_request(),
but that would make the effort of trying to call ktime_get_ns()
once in vain. Instead we can reuse throtl_size field, and use
it for both block stats and block throttle, and adjust the
logic in blk_mq_poll_stats_bkt() accordingly.

This reverts commit b03755ad6f33b7b8cd7312a3596a2dbf496de6e7.
This is sad, and done for all the wrong reasons. Because that commit is
good, and does exactly what it says: avoids a lot of small disk requests
for the inode table read-ahead.
However, it turns out that it causes an entirely unrelated problem: the
getrandom() system call was introduced back in 2014 by commit
c6e9d6f38894 ("random: introduce getrandom(2) system call"), and people
use it as a convenient source of good random numbers.
But part of the current semantics for getrandom() is that it waits for
the entropy pool to fill at least partially (unlike /dev/urandom). And
at least ArchLinux apparently has a systemd that uses getrandom() at
boot time, and the improvements in IO patterns means that existing
installations suddenly start hanging, waiting for entropy that will
never happen.
It seems to be an unlucky combination of not _quite_ enough entropy,
together with a particular systemd version and configuration. Lennart
says that the systemd-random-seed process (which is what does this early
access) is supposed to not block any other boot activity, but sadly that
doesn't actually seem to be the case (possibly due bogus dependencies on
cryptsetup for encrypted swapspace).
The correct fix is to fix getrandom() to not block when it's not
appropriate, but that fix is going to take a lot more discussion. Do we
just make it act like /dev/urandom by default, and add a new flag for
"wait for entropy"? Do we add a boot-time option? Or do we just limit
the amount of time it will wait for entropy?
So in the meantime, we do the revert to give us time to discuss the
eventual fix for the fundamental problem, at which point we can re-apply
the ext4 inode table access optimization.

some code that was thought unnecessary; however, since then KVM has
grown quite a few cond_resched()s and for that reason the simplified

page tables while the others keep adding to them. This adds back the

unnecessary after all.

Pull RISC-V fix from Paul Walmsley:
"Last week, Palmer and I learned that there was an error in the RISC-V
kernel image header format that could make it less compatible with the
ARM64 kernel image header format. I had missed this error during my
original reviews of the patch.
The kernel image header format is an interface that impacts
bootloaders, QEMU, and other user tools. Those packages must be
updated to align with whatever is merged in the kernel. We would like
to avoid proliferating these image formats by keeping the RISC-V
header as close as possible to the existing ARM64 header. Since the
arch/riscv patch that adds support for the image header was merged
with our v5.3-rc1 pull request as commit 0f327f2aaad6a ("RISC-V: Add
an Image header that boot loader can parse."), we think it wise to try
to fix this error before v5.3 is released.
The fix itself should be backwards-compatible with any project that
has already merged support for premature versions of this interface.
It primarily involves ensuring that the RISC-V image header has
something useful in the same field as the ARM64 image header"

Since commit 795fe54c2a828099e ("bfq: Add per-device weight"), bfq uses
blkg_conf_prep() and blkg_conf_finish(), which are not exported. So, it
causes linkage error if bfq compiled as a module.

Standard integer promotion is already done and %hx and %hhx is useless
so do not encourage the use of %hh[xudi] or %h[xudi].
As Linus said in:
https://lore.kernel.org/lkml/CAHk-=wgoxnmsj8GEVFJSvTwdnWm8wVJthefNk2n6+4TC=20e0Q@mail.gmail.com/
It's a pointless warning, making for more complex code, and
making people remember esoteric printf format details that have no
reason for existing.
The "h" and "hh" things should never be used. The only reason for them
being used if if you have an "int", but you want to print it out as a
"char" (and honestly, that is a really bad reason, you'd be better off
just using a proper cast to make the code more obvious).
So if what you have a "char" (or unsigned char) you should always just
print it out as an "int", knowing that the compiler already did the
proper type conversion.

Remove the clever example about read-write lock because this type of
lock is not recommended anymore (according to the very same document).
So there is no reason to teach clever things that people should not do.
