Pull EFI updates from Ard Biesheuvel:
"Note the removal of the EFI fake memory map support - this is believed
to be unused and no longer worth supporting. However, we could easily
bring it back if needed.
With recent developments regarding confidential VMs and unaccepted
memory, combined with kexec, creating a known inaccurate view of the
firmware's memory map and handing it to the OS is a feature we can
live without, hence the removal. Alternatively, I could imagine making
this feature mutually exclusive with those confidential VM related
features, but let's try simply removing it first.
Summary:
- Drop support for the 'fake' EFI memory map on x86
- Add an SMBIOS based tweak to the EFI stub instructing the firmware
on x86 Macbook Pros to keep both GPUs enabled
- Replace 0-sized array with flexible array in EFI memory attributes
table handling

entrypoint on x86

condition
- Cosmetic tweak for arm64 KASLR loading logic"

Most of this is part of my ongoing work to clean up the system call
tables. In this bit, all of the newer architectures are converted to
use the machine readable syscall.tbl format instead in place of complex
macros in include/uapi/asm-generic/unistd.h.
This follows an earlier series that fixed various API mismatches
and in turn is used as the base for planned simplifications.
The other two patches are dead code removal and a warning fix.

The devicetree updates are fairly well spread out across platforms,
with Qualcomm making up about a third of the total.
There are three new SoCs in existing product families this:
- NXP i.MX95 is a variant of i.MX93, now with six Cortex-A55 cores
instead of just two as well as a GPU and more high-speed I/O
devices.
- Qualcomm QCS8550 is a variant of SM8550 for IOT devices
- Airoha EN7581 is a 10G-PON network chip and related to
the MT7981 Wireless router chip from its parent Mediatek.
In total there are 58 new machines, including four riscv
boards and eight for 32-bit arm.
The most exciting new addition is probably a pair of laptops
based on the Qualcomm x1e80100 (Snapdragon X1 Elite) chip,
the Asus Vivobook S15 and the Lenovo Yoga Slim7x.
Other noteworthy new additions are:
- A total of 20 Qualcomm based machines, mostly Android devices
from Samsung, Motorola and LG, as well as a wireless router
and some reference designs
- Six NXP i.MX based machines, mostly industrial boards along
with some reference designs
- Mediatek sees some interesting Filogic based routers
including the "OpenWRT One", a few new Chromebooks as
well as single-board computers.
- Four machines from Solidrun based on Marvell cn913x,
replacing the older Armada 8000 based counterparts
- The four Amlogic machines are all set top boxes or reference
designs for them
- The nine new Rockchips machines are mostly single-board
computers including some interesting ones based on the
rk3588 chip like the ROCK 5 ITX board and the CM3588
with its four NVMe slots
- The RISC-V boards are all single-board computers based on
Starfive JH7110, Microchip MPFS and Allwinner D1, which all
had similar boards already
There are also a lot of updates to already supported machines,
notably for the TI K3, Rockchips, Freescale and of course
Qualcomm platforms.

The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
samsung, imx, zynq and amlogic platoforms are farily small maintenance
changes, either addressing minor mistakes or enabling additional hardware.
The qualcomm platform changes add a number of features and are larger
than the other ones combined, introducing the use of linux/cleanup.h
across several drivers, adding support for Snapdragon X1E and other
SoCs in platform drivers, a new "protection domain mapper" driver, and a
"shared memory bridge" driver.
The cznic "turris omnia" router based on Marvell Armada gets a platform
driver that talks to the board specific microcontroller.
The reset and cache subsystems get a few minor updates to SoC specific
drivers, while the ff-a, scmi and optee firmware drivers get some
code refactoring and new features.

samsung, imx, zynq and amlogic platoforms are fairly small maintenance
changes, either addressing minor mistakes or enabling additional
hardware.
The qualcomm platform changes add a number of features and are larger
than the other ones combined, introducing the use of linux/cleanup.h
across several drivers, adding support for Snapdragon X1E and other
SoCs in platform drivers, a new "protection domain mapper" driver, and
a "shared memory bridge" driver.
The cznic "turris omnia" router based on Marvell Armada gets a
platform driver that talks to the board specific microcontroller.
The reset and cache subsystems get a few minor updates to SoC specific
drivers, while the ff-a, scmi and optee firmware drivers get some code
refactoring and new features"

VM Service Module (SVSM).
When running over a SVSM, different services can run at different
protection levels, apart from the guest OS but still within the
secure SNP environment. They can provide services to the guest, like
a vTPM, for example.
This series adds the required facilities to interface with such a SVSM
module.

There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper and
allowing the DMA mapping decision to be done per transfer instead of
per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

anyway). We also have one fix for the KUnit tests, and a bunch of

Pull power sequencing updates from Bartosz Golaszewski:
"This has been in development since last year's Linux Plumbers
Conference and was inspired by the need to enable support upstream for
Bluetooth/WLAN chips on Qualcomm platforms.
The main problem we're fixing is powering up devices which are
represented as separate objects in the kernel (binding to different
drivers) but which share parts of the power-up sequence and thus need
some kind of a mediator who knows the possible interactions and can
assure they don't interfere with neither device's bring up. An example
of such an inter-driver interaction is the WCN family of BT/WLAN chips
from Qualcomm of which some models require the user to observe a
certain delay between driving the bt-enable and wlan-enable GPIOs.
This is not a new problem but up to this point all attempts at
addressing it ended up hitting one wall or another and being dropped.
The main obstacle was the fact that most these attempts tried to
introduce the concept of a "power sequence" into the device-tree
bindings which breaks the main DT rule: describe the hardware, not its
behavior. The solution I proposed focuses on making the power
sequencer drivers interpret the actual HW description flexibly. More
details on that are in the linked cover letter.
The second problem fixed here is powering up PCI devices before they
are detected on the bus. This is achieved by creating special platform
devices for device-tree nodes describing hard-wired PCI devices which
bind to the so-called PCI power control drivers which enable required
resources and trigger a bus rescan once the controlled device is up
then setup the correct devlink hierarchy for power-management.
By combining the two new frameworks we implemented the power
sequencing PCI power control driver which is capable of powering up
the WLAN modules of the QCom WCN family of chipsets.
All this has spent a significant amount of time in linux-next and
enabled WLAN/BT support on several Qualcomm platforms. To further
prove that this is useful and needed: right after this was picked up
into next, I was sent a series using the subsystem for a similar
use-case on Amlogic platforms.
This contains the core power sequencing framework, the first driver,
PCI changes using the pwrseq library (blessed by Bjorn Helgaas) and
some fixes that came later"

- Fix selftest printf format mismatch in expect_str_buf_eq()
- Stop using brk() and sbrk() when testing against musl, which
implements these two functions with ENOMEM
- Make tests use -Werror to force failure on compiler warnings
- Add limits for the {u,}intmax_t, ulong and {u,}llong types
- Implement strtol() and friends
- Add facility to skip nolibc-specific tests when running against
non-nolibc libraries
- Implement strerror()
- Also use strerror() on nolibc when running kselftests

A simple but odd single-process litmus test acquires and immediately
releases a lock, then calls spin_is_locked(). LKMM acts if it was
a deadlock due to an assumption that spin_is_locked() will follow a
spin_lock() or some other process's spin_unlock(). This litmus test
manages to violate this assumption because the spin_is_locked() follows
the same process's spin_unlock().
This series fixes this bug, reorganizes and optimizes the lock.cat model,
and updates documentation.

This series provides emulated one-byte cmpxchg() support for ARM
using the cmpxchg_emu_u8() function that uses a four-byte cmpxchg()
to emulate the one-byte variant.
Similar patches for emulation of one-byte cmpxchg() for arc, sh, and
xtensa have not yet received maintainer acks, so they are slated for
the v6.12 merge window.
