Pull spi updates from Mark Brown:
"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.
Summary:
- 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, MediaTek MT8195"

Pull ARM Nuvoton WPCM450 platform support from Arnd Bergmann:
"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"

Pull ARM devicetree updates from Arnd Bergmann:
"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"

Pull irq updates from Thomas Gleixner:
"The usual updates from the irq departement:
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.
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

Newer Xen versions expose two Xen feature flags to tell us if the domain
is directly mapped or not. Only when a domain is directly mapped it
makes sense to enable swiotlb-xen on ARM.
Introduce a function on ARM to check the new Xen feature flags and also
to deal with the legacy case. Call the function xen_swiotlb_detect.

"Another smaller set of fixes for three of the Arm platforms:

Fix swapped mmc device order also for omap3 that got changed with
the recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the
aliases should be board specific, all the mmc device instances are
all there in the SoC, and we do probe them by default so that PM
runtime can idle the devices if left enabled from the bootloader.
Qualcomm Snapdragon:
This bypasses the recently introduced interconnect handling in
the GENI (serial engine) driver when running off ACPI, as this
causes the GENI probe to fail and the Lenovo Yoga C630 to boot
without keyboard and touchpad.

Since uprobes is not supported for thumb, check that the thumb bit is
not set when matching the uprobes instruction hooks.
The Arm UDF instructions used for uprobes triggering
(UPROBE_SWBP_ARM_INSN and UPROBE_SS_ARM_INSN) coincidentally share the
same encoding as a pair of unallocated 32-bit thumb instructions (not
UDF) when the condition code is 0b1111 (0xf). This in effect makes it
possible to trigger the uprobes functionality from thumb, and at that
using two unallocated instructions which are not permanently undefined.

Debian's clang carries a patch that makes the default FPU mode
'vfp3-d16' instead of 'neon' for 'armv7-a' to avoid generating NEON
instructions on hardware that does not support them:
https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/raw/5a61ca6f21b4ad8c6ac4970e5ea5a7b5b4486d22/debian/patches/clang-arm-default-vfp3-on-armv7a.patch
https://bugs.debian.org/841474
https://bugs.debian.org/842142
https://bugs.debian.org/914268
This results in the following build error when clang's integrated
assembler is used because the '.arch' directive overrides the '.fpu'
directive:
arch/arm/crypto/curve25519-core.S:25:2: error: instruction requires: NEON
vmov.i32 q0, #1
^
arch/arm/crypto/curve25519-core.S:26:2: error: instruction requires: NEON
vshr.u64 q1, q0, #7
^
arch/arm/crypto/curve25519-core.S:27:2: error: instruction requires: NEON

^
arch/arm/crypto/curve25519-core.S:28:2: error: instruction requires: NEON
vmov.i32 d4, #19
^
Shuffle the order of the '.arch' and '.fpu' directives so that the code
builds regardless of the default FPU mode. This has been tested against
both clang with and without Debian's patch and GCC.
