Fixes boot failures on 6.9 on PPC_BOOK3S_32 machines using Open Firmware.
On these machines, the kernel refuses to boot from non-zero
PHYSICAL_START, which occurs when CRASH_DUMP is on.
Since most PPC_BOOK3S_32 machines boot via Open Firmware, it should
default to off for them. Users booting via some other mechanism can still
turn it on explicitly.
Does not change the default on any other architectures for the
time being.

Commit d1703dc7bc8e ("RISC-V: Detect unaligned vector accesses
supported") removed the default handlers for handle_misaligned_load()
and handle_misaligned_store(). When the kernel is compiled without
RISCV_SCALAR_MISALIGNED, these handlers are never defined, causing
compilation errors.

RISC-V Devicetrees for v6.13
StarFive:
Support for the DeepComputing FML13V01, a Framework laptop compatible
with a JH7110. This board is fairly different to the more standard SBCs
offerings that the kernel already supports, so there's also some
refactoring of jh7110-common.dtsi to move out nodes unused on the new
board.
Spacemit:
A vendor prefix I grabbed from the basic support series, since its
dependencies are not yet ready but peripheral drivers have started being
merged.

T-HEAD Devicetrees for v6.13, part 2

Linus W and will be included in the 6.13 pinctrl PR.
The TH1520 GPIO controllers are already supported by the gpio-dwapb

This implements [cmp]xchgXX() macros using Zacas and Zabha extensions

It also uses Ziccrse to provide the qspinlock implementation.

In order to produce a generic kernel, a user can select
CONFIG_COMBO_SPINLOCKS which will fallback at runtime to the ticket
spinlock implementation if Zabha or Ziccrse are not present.
Note that we can't use alternatives here because the discovery of
extensions is done too late and we need to start with the qspinlock
implementation because the ticket spinlock implementation would pollute
the spinlock value, so let's use static keys.
This is largely based on Guo's work and Leonardo reviews at [1].

Now that Zacas is supported in the kernel, let's use the double word
atomic version of amocas to improve the SLUB allocator.
Note that we have to select fixed registers, otherwise gcc fails to pick
even registers and then produces a reserved encoding which fails to

riscv does not have lr instructions on byte and halfword but the
qspinlock implementation actually uses such atomics provided by the
Zabha extension, so those sizes are legitimate.

asm/cmpxchg.h will soon need riscv_has_extension_unlikely() macros and
then needs to include asm/cpufeature.h which introduces a lot of header
circular dependencies.
So move the riscv_has_extension_XXX() macros into their own header which
prevents such circular dependencies by including a restricted number of
headers.

Pull SoC fixes from Arnd Bergmann:
"Where the last set of fixes was mostly drivers, this time the
devicetree changes all come at once, targeting mostly the Rockchips,
Qualcomm and NXP platforms.
The Qualcomm bugfixes target the Snapdragon X Elite laptops,
specifically problems with PCIe and NVMe support to improve
reliability, and a boot regresion on msm8939.
Also for Snapdragon platforms, there are a number of correctness
changes in the several platform specific device drivers, but none of
these are as impactful.
On the NXP i.MX platform, the fixes are all for 64-bit i.MX8 variants,
correcting individual entries in the devicetree that were incorrect
and causing the media, video, mmc and spi drivers to misbehave in
minor ways.
The Arm SCMI firmware driver gets fixes for a use-after-free bug and
for correctly parsing firmware information.
On the RISC-V side, there are three minor devicetree fixes for
starfive and sophgo, again addressing only minor mistakes. One device
driver patch fixes a problem with spurious interrupt handling"

To avoid duplication of inline asm between C and Rust, we need to
import the inline asm from the relevant `jump_label.h` header into Rust.
To make that easier, this patch updates the header files to expose the
inline asm via a new ARCH_STATIC_BRANCH_ASM macro.
The header files are all updated to define a ARCH_STATIC_BRANCH_ASM that
takes the same arguments in a consistent order so that Rust can use the
same logic for every architecture.

Since 135225a363ae timekeeping_cycles_to_ns() handles large offsets which
would lead to 64bit multiplication overflows correctly. It's also protected
against negative motion of the clocksource unconditionally, which was
exclusive to x86 before.
timekeeping_advance() handles large offsets already correctly.
That means the value of CONFIG_DEBUG_TIMEKEEPING which analyzed these cases
is very close to zero. Remove all of it.

Pull RISC-V fixes from Palmer Dabbelt:
- Avoid accessing the early boot ACPI tables via unsafe memory
attributes, which can result in incorrect ACPI table data appearing.
This can cause all sorts of bad behavior.
- Avoid compiler-inserted library calls in the VDSO.
- GCC+Rust builds have been disabled, to avoid issues related to ISA
string mismatched between the GCC and LLVM Rust implementations.
- The NX flag is now set in the EFI PE/COFF headers, which is necessary
for some distro GRUB versions to boot images.
- A fix to avoid leaking DT node reference counts on ACPI systems
during cache info parsing.
- CPU numbers are now printed as unsigned values during hotplug.
- A pair of build fixes for usused macros, which can trigger warnings
on some configurations.

The FML13V01 board from DeepComputing incorporates a StarFive JH7110 SoC.
It is a mainboard designed for the Framework Laptop 13 Chassis, which has
(Framework) SKU FRANHQ0001.
The FML13V01 board features:
- StarFive JH7110 SoC
- LPDDR4 8GB
- eMMC 32GB or 128GB
- QSPI Flash
- MicroSD Slot
- PCIe-based Wi-Fi
- 4 USB-C Ports
- Port 1: PD 3.0 (60W Max), USB 3.2 Gen 1, DP 1.4 (4K@30Hz/2.5K@60Hz)
- Port 2: PD 3.0 (60W Max), USB 3.2 Gen 1
- Port 3 & 4: USB 3.2 Gen 1
Create the DTS file for the DeepComputing FML13V01 board. Based on
'jh7110-common.dtsi', usb0 is enabled and is set to operate as a "host".

The JH7110 USB0 can operate as a dual-role USB device. Different
boards can have different configuration.
For all current boards this device operates in peripheral mode, but
on a new board this operates in host mode. This property will no
longer be common, so define the "dr_mode" property in the board files
rather than in the common DTSI file.

Earlier this year a new DTSI file was created to define common
properties for the StarFive VisionFive 2 and Milk-V Mars boards,
both of which use the StarFive JH7110 SoC. The Pine64 Star64
board has also been added since that time.
Some of the nodes defined in "jh7110-common.dtsi" are enabled in
that file because all of the boards including it "want" them
enabled.
An upcoming patch enables another JH7110 board, but for that
board not all of these common nodes should be enabled. Prepare
for supporting the new board by avoiding enabling these nodes in
"jh7110-common.dtsi", and enable them instead in these files:
jh7110-milkv-mars.dts
jh7110-pine64-star64.dts
jh7110-starfive-visionfive-2.dtsi

__pa() is only intended to be used for linear map addresses and using
it for initial_boot_params which is in fixmap for arm64 will give an
incorrect value. Hence save the physical address when it is known at
boot time when calling early_init_dt_scan for arm64 and use it at kexec
time instead of converting the virtual address using __pa().
Note that arm64 doesn't need the FDT region reserved in the DT as the
kernel explicitly reserves the passed in FDT. Therefore, only a debug
warning is fixed with this change.
