git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linux
Pull liveupdate updates from Mike Rapoport:
- Several small fixes to KHO and LiveUpdate selftest
- A series that renames "KHO scratch" to "KHO bootmem" because this
memory is way more important in kexec'ed kernels rather than in the
original cold boot kernel and the new name reflects it
* tag 'liveupdate-v7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linux:
kho: do not reserve empty per-node bootmem areas
selftests/liveupdate: Prefer KVM and HVF over TCG in vmtest.sh
kho: rename kho_scratch= commandline parameter to kho_bootmem=
kho: rename KHO scratch to KHO bootmem

git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
- Set the LoaderDevicePartUUID EFI variable from the stub to help
systemd discover the file system layout when booting straight into
Linux without GRUB or systemd-boot (Vincent Mailhol)
- Some GUID deduplication work from Vincent
- Remove pointless UTF16->UTF8 and vice versa conversions from the stub
- Some kmap() -> kmap_local_page() conversions in the capsule loader
- Add a runtime control to en/disable EFI runtime services so that
PREEMPT_RT systems can enable them as needed
- Add a 'nostatfs' mount option to efivarfs so that the cost of
querying the EFI variable store (which is already rate limited) can
be avoided entirely on systems where it is disproportionately costly
- Rework the EFI libstub Makefile to align x86 with other
architectures, and inherit/adapt the global CFLAGS variable rather
than reconstruct it from scratch
- Constify attributes of statically allocated sysfs nodes
- Avoid register x18 when building the arm64 EFI stub, in order to
comply with the UEFI spec, and to permit it to execute in a context
where x18 is special
- Preserve the physical addresses of all EFI config tables that may be
of interest to an incoming kexec kernel
- Add some LKDTM tests for EFI runtime crashes where the faulting
address is inside a EFI memory region
- Other minor bug fixes and cosmetic cleanups

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI support updates from Rafael Wysocki:
"The most significant change here is the rework of the core ACPI device
enumeration code to avoid initializing ACPI power management
prematurely for devices with unmet dependencies. This essentially is a
problem fix, but it requires taking PCI device enumeration ordering
into account among other things, so it is far from straightforward.
There was an attempt to do this in the 7.3 time frame that had to be
reverted, so this time it is done much more carefully.
There is also an ACPI thermal control update rearranging the code to
register thermal class cooling devices under specific parents, which
is visible in sysfs. This helps to figure out what is represented by
those devices much more easily, but it also allows the binding of
cooling devices to trip points in thermal zones to be adjusted so it
need not rely on specific cooling device data usage in thermal
drivers.
From the number of commits perspective, the most visible part is the
one replacing acpi_get_first_physical_node() with
acpi_bus_get_primary_device() everywhere and dropping the former that
was inherently racy and generally unsafe to use. Fortunately, the
maintainers involved responded timely and all of that could be done
within one development cycle.
Another quite visible part is Dave Jiang's series fixing multiple
issues reported by Sashiko in the ACPI APEI support code with a PCI
AER improvement on top. It took several iterations of this to make
Sashiko happy and the code in question should be much more robust
going forward.
One other thing worth mentioning separately is that the ACPI bus type
is now going to be registered as a "companion" one and it will not be
possible to register a driver binding directly to a struct
acpi_device. All of the existing users of those drivers in the tree
were converted to platform drivers in the previous cycles, so this is
just a final step in a longer journey.
Apart from the above, there are many fixes, mostly in drivers, with a
noticeable exception of a fix in the code binding devices to their
ACPI companions, new IOVT IOMMU support in ACPICA, new _Ixx object
support for suspend-to-idle on x86, multiple new quirks, mostly
related to unused ACPI power resources and backlight handling, and
assorted cleanups.
Specifics:
- Make the core ACPI device enumeration code stop attempting to
initialize ACPI power management for devices before they are known
to be present and functional (Rafael Wysocki)
- Simplify and clean up the core ACPI device enumeration code on top
of the previous adjustment and reduce debug noise coming from it
(Rafael Wysocki)
- Fix locking in the code binding devices to their ACPI companions,
prevent it from replacing a valid ACPI companion pointer with NULL
incidentally, improve its messaging (including debug noise
reduction), and reduce its overhead by making it skip the cases in
which no ACPI companion may exist early (Rafael Wysocki)
- Reduce runtime memory footprint of struct acpi_device by
rearranging fields in it (Andy Shevchenko)
- Update the driver core to allow bus types without drivers to be
registered as "companion bus types" without driver-related sysfs
attributes and register the ACPI bus type as a companion one
(Rafael Wysocki)
- Use strscpy() instead of strcpy() in the ACPI sysfs interface
(Ruslan Vagner)
- Remove __meminitdata from hmat_adist_nb declaration preserving it
even when CONFIG_MEMORY_HOTPLUG is not set to prevent notifier
chain corruption in some cases (Alejandro Lucero)
- Prevent a NULL pointer dereference when attempting to read the
table length after a mapping bookkeeping failure during an initrd
override invocation with permanent table mappings enabled (Slavin
Liu)
- Use for_each_populated_zone() in get_node_num() in the MRRM table
pareser (Sang-Heon Jeon)
- Use vsnprintf() in acpi_os_vprintf() to prevent memory corruption
resulting from overly long diagnostic messages that may not fit
into a static buffer used by ACPICA and may be produced by a
malformed ACPI table (Vlatko Kosturjak)
- Ignore leading root scope prefix in string _UID match to allow AMD
IOMMU matching to work as expected in some cases (Mario
Limonciello)
- Adjust message printing macros for ACPI objects to use dev_fmt()
for more consistency with the analogous dev_*() macros (Rafael
Wysocki)
- Add _Ixx GPE wake indicator support to the x86 suspend-to-idle
handling code (Saranya Gopal)
- Clear driver_data before free in the ACPI PCI Link driver to
prevent a dangling pointer from being used later (Jiale Yao)
- Accumulate the queued flag across error sections of a CPER record
in ghes_do_proc() to prevent it from being cleared by a later
section or entry that does not queue memory-failure work (Breno
Leitao)
- Map a raw PCI AER Capability image field by field to prevent
information loss from occurring while processing it (Dave Jiang)
- Update a stale driver source reference in the ACPI APEI EINJ driver
documentation (Prabhakar Pujeri)

- Update the thermal core to allow the registration of thermal class
cooling devices under specific parents and convert the ACPI fan,
ACPI processor, and ACPI video bus device drivers to do so (Rafael
Wysocki)
- Adjust the ACPI thermal zone driver to use thermal class cooling
device parent information for binding cooling devices to trip
points in thermal zones (Rafael Wysocki)
- Use cooling device data that is a better match for a given driver
instead of a struct acpi_device pointer that had to be used for
this purpose previously in the ACPI fan and processor drivers
(Rafael Wysocki)
- Fix acpi_thermal_guess_offset() in the ACPI thermal zone driver for
thermal zone devices with a 273.0°K offset (Hans de Goede)

Two bugs were found in the arm64 EFI runtime support that weren't caught
by LKDTM. The existing EFI_RUNTIME_CRASH test instructs the firmware to
write to kernel memory that is mapped read-only, which usually fails as
expected. However, this does not exercise the runtime mapping logic in
the kernel, nor the fault recovery logic when the faulting address is
inside the EFI runtime memory regions itself.
So add two more test cases:
- a write to R/O memory test that uses the firmware's own executable
memory as an output buffer
- a branch to memory that is occupied by the firmware's runtime services
function table, which is usually mapped non-execute.
This depends on the EFI memory attributes table having been exposed by
the firmware and having been taken into account by the runtime mapping
code, so this is used as a prerequisite by the new tests, otherwise it
produces an XFAIL.

The addresses of the MOK variable table, the confidential computing
secret area and the unaccepted memory table in struct efi are only
initialized to EFI_INVALID_TABLE_ADDR if support for the respective
table is enabled, and are left at 0 otherwise. This is harmless for
the existing users, which are compiled out in that case, but code that
consumes the table addresses in struct efi generically, such as a kexec
loader that passes the configuration tables on to the incoming kernel,
would mistake 0 for a valid table address.
So initialize all of them unconditionally: efi_config_parse_tables()
only assigns them if support for the table is enabled, and so they
remain EFI_INVALID_TABLE_ADDR otherwise.

The physical address of the LINUX_EFI_MEMRESERVE configuration table is
only kept in __initdata, but a kexec loader that runs the incoming
kernel's EFI stub needs it in order to pass the table on, so that the
persistent memory reservations made by this kernel and its predecessors
(e.g., for the GICv3 LPI tables) are carried over.
So move it into struct efi, alongside the addresses of the other EFI
configuration tables that may be passed on in this way.

The LINUX_EFI_MEMRESERVE table is the root of a linked list of memory
reservations that need to persist across kexec, such as the GICv3 LPI
pending and property tables, which cannot be moved once the
redistributors have been enabled. Each kernel adds its own reservations
to the list that it finds via the EFI configuration table, and honours
the ones made by its predecessors.
The EFI stub installs a new, empty table unconditionally, replacing any
existing one. This is fine on a cold boot, but not if the stub is being
executed by a loader that passes on the configuration tables of an
earlier kernel, e.g., a kexec loader that runs the incoming kernel's EFI
stub, as the reservations made by earlier kernels would be lost.
So leave an existing table in place, and only install a new one if none
exists yet.

Commit 4b2c033b5bc9 ("efi/runtime-wrappers: retire the worker if a wedged
call ever returns") parks the efi_rts_wq worker instead of completing the
call if EFI runtime services have been disabled by the time the firmware
returns. The assumption is that this only happens if __efi_queue_work()
has given up waiting for the call.
However, arm64 also disables EFI runtime services when it recovers from a
synchronous exception taken by the firmware: efi_runtime_fixup_exception()
clears EFI_RUNTIME_SERVICES and unwinds the call so that it returns
EFI_ABORTED to efi_call_rts(), while the caller is still waiting for the
completion. The worker now parks without signalling it, so the caller is
stuck for the full EFI_RTS_TIMEOUT of 120 seconds, after which it reports
that the firmware is wedged, which is misleading.
x86 is not affected, as it signals the completion from its page fault
handler before parking the worker.
So record explicitly that the caller has given up on the call, and only
park the worker in that case.

The x86 stub replaces KBUILD_CFLAGS with a short list of its own, so new
kernel-wide compiler options go missing, unless explicitly remembered
or when lacking them breaks the build, e.g. commit 5ff8ad3909524
("kbuild: Add '-fms-extensions' to areas with dedicated CFLAGS")
did. Today, several still go missing that are provided to non-x86
stub builds, e.g. -ftrivial-auto-var-init, -fzero-call-used-regs,
-fstrict-flex-arrays=3, and the various kernel's warnings.
Flip the x86 option logic to match the other architectures. Since the
x86 stub is linked into the decompressor rather than the kernel proper,
remove the kernel code model, the i386 register calling convention,
and the kernel's reduced stack alignment, along with the retpoline and
return thunks and the call padding, which only the kernel provides,
and disable kernel stack erasing as the other architectures do. The
existing -mcmodel=small, -march=i386, and -fPIC still get overrides.
Build with -fcf-protection=none, since nothing enables IBT while the
stub runs: the firmware applies forward-edge CFI only to images that
advertise it, which bzImage does not.

efi_stub_entry() and efi_handover_entry() are entered from efi-mixed.S
and, through the efi32_stub_entry() and efi64_stub_entry() aliases, by
boot loaders using the EFI handover protocol, but have no prototypes.
Declare them in x86-stub.h, as asmlinkage, so that the stub can be built
with the kernel's -Wmissing-prototypes.

The UEFI specification designates x18, the platform register, as "do not
use" on AArch64, so that UEFI code is compatible both with an OS that
assigns a fixed role to x18, and with one that uses it as a temporary
register.
The arm64 EFI stub and the EFI zboot decompressor only avoid x18 if the
kernel is built with shadow call stacks, as that is the only case where
-ffixed-x18 is added to KBUILD_CFLAGS, which the stub inherits.
Otherwise, the compiler is free to use x18 as a temporary register, and
it does so.
So pass -ffixed-x18 unconditionally when building the stub for arm64,
so that the image can be run by loaders that rely on x18 being left
alone, such as a kernel that uses it for its shadow call stack.

Cover the case where the post_run client hook fails: cs_dsp_run() must
return the error and the DSP must not be left marked as running, and a
subsequent run must be able to start it again.
The test fails without the previous patch and passes with it. Full suite
run (UML, KUnit) on top of that patch:
before: Ran 5829 tests: passed: 5825, failed: 4

cs_dsp_run() sets dsp->running = true once the core has been started, but
the error path below it only stops and disables the core, leaving the flag
set. The first thing that can fail after that point is the post_run client
hook, and it is reachable in mainline: wm_adsp registers
wm_adsp_event_post_run(), which can fail in wm_adsp_buffer_init().
The core is then stopped and disabled, but dsp->running still reads true,
and that stale state is acted on elsewhere: cs_dsp_coeff_write_ctrl() and
cs_dsp_coeff_read_ctrl() talk to the DSP when ctl->dsp->running is set, and
client drivers use the flag to decide whether the firmware is up (cs35l41
checks cs_dsp.running before its early events and on hibernate/resume).
The flag cannot simply be moved below the hook: post_run hooks such as
wm_adsp_event_post_run() read controls while they run, and
cs_dsp_coeff_read_ctrl() only goes to the DSP when the flag is set.
Clear the flag on the error path, before the core is stopped - the order
cs_dsp_stop() already uses.

The device probe passes zeroes for all seven argument registers to
arm_smccc_1_1_invoke(). On ARM32 Thumb-2, this binds an input to r7 and
GCC 8.5 reports "r7 cannot be used in asm here".
The current smccc_devices entries need at most one argument after the
function ID: TRNG_VERSION has none and RSI_ABI_VERSION takes a requested
version. Pass zero for that argument and omit the unused arguments,
avoiding the r7 constraint. Check argument requirements when adding new
probe functions to smccc_devices.

Since commit 48ebe1cbbeb51 ("kbuild: compress the kernel with pigz if
available"), cmd_gzip runs pigz through scripts/jobserver-exec, which
takes the job slots make has free. GNU Make passes the jobserver pipe
only to recipes it treats as recursive, but leaves --jobserver-auth in
MAKEFLAGS for all of them. The make 4.3 in CentOS Stream 9 also hides
the pipe in sub-makes (a backport of the fix for GNU Make bug 58232), so
jobserver-exec cannot open it, runs pigz on one thread, and prints:
WARNING: Unable to reopen jobserver read-side pipe: FileNotFoundError(2, 'No such file or directory')
Mark every recipe that can run cmd_gzip as recursive with "+", as
commit ecab4115c44cc ("kbuild: mark `rustc` (and others) invocations as
recursive") did for rustc. Besides the $(call if_changed,gzip) rules,
this covers those that choose gzip through a variable: the built-in
initramfs in usr/Makefile (which rcutorture's kvm.sh builds), the EFI
zboot image, and the arm, csky, and mips compressed images. As with
rustc, "make -n" now runs these recipes, including those that choose
through a variable when they select another compressor. Also update the
gzip entry in Documentation/kbuild/makefiles.rst, as suggested in
review.
Tested with GNU Make 4.3 plus CentOS Stream 9's make-4.3-cloexec.patch,
GCC 16.2.0, and -j64, on ARCH=x86_64, arm64, and arm defconfig, and
ARCH=x86_64 defconfig with a built-in initramfs: none of them prints the
warning, and pigz gets the free job slots (-p 54, 64, and 50 for the
kernel image). Without this change, the x86_64 builds print it for the
kernel image and for the initramfs.

The term "KHO scratch" is vague and overloaded.
For one, it does not accurately describe what the memory is for. From
KHO's perspective, it is memory passed by the previous kernel that is
guaranteed to have no allocations and hence it is safe to allocate from.
For another, the term is overloaded. KHO also knows to discover other
ranges of memory that don't have any preservations and are safe to
allocate from. This is done by kho_extend_scratch(). These areas, while
called "scratch", are completely different from the chunk of memory
passed by the previous kernel for early boot allocations.
Rename "KHO scratch" to "KHO boot memory", or "KHO bootmem" in short.
Update all function names, variable names, comments, and documentation
to use this.
Call the discovered areas "noprsrv", matching what memblock would see
them as. Rename kho_extend_scratch() to reflect this.
This patch largely has no functional changes. The only functional
changes are renames of debugfs files from "scratch_phys" and
"scratch_len" to "bootmem_phys" and "bootmem_len" respectively.

The term "KHO scratch" is vague. It does not accurately describe what
the memory is for. Generally, scratch is for things that don't contain
anything useful. This is not true.
For memblock, KHO_SCRATCH is the _only_ useful memory during a KHO boot.
It is memory passed by the previous kernel that is guaranteed to have no
preserved pages, and so is the only thing safe to allocate from early in
boot.
In addition, KHO now has the ability to discover other "scratch" areas.
These aren't directly passed by the previous kernel. Instead, they are
found by searching the KHO preserved memory map.
Memblock does not care about the difference between the two. From
memblock's perspective, both are memory areas with no preservations and
so they are safe to allocate from before KHO fully initializes.
Rename MEMBLOCK_KHO_SCRATCH to MEMBLOCK_KHO_NOPRSRV. This name clearly
shows what the memory is for from memblock's perspective. Update
memblock functions and comments that refer to scratch to use noprsrv.
There are no functional changes apart from the flag name change in
debugfs.

The service controller currently polls FPGA configuration status at a
fixed 1 second interval until the 30 second timeout expires. This leads
to slow response time for fast-returning commands and unnecessary delay
before reporting completion.
Introduce two polling modes:
- Fast polling: 20 ms interval for up to 50 iterations (≈1 s total)
- Slow polling: 500 ms interval for up to 29 seconds
A new helper, svc_cmd_poll_status(), abstracts the polling logic and
replaces the existing loop in svc_thread_cmd_config_status(). This allows
the driver to respond quickly to short operations while still handling
long-running configuration commands within the same overall timeout
window.

This exclusion caused receive_cb to never be invoked for these commands

On Agilex5, DDR starts at 0x8000_0000 which is outside the SDM's
addressable range. When SMMU is active, the driver must allocate
DMA-coherent buffers and pass IOVAs (not physical addresses) to ATF.
Add SVC_SDM_DMA_ADDR_BITS (29) and SVC_SDM_DMA_ADDR_OFFSET
(0x8000_0000) to constrain IOVAs to the 0-512 MB window the SDM can
reach and to satisfy ATF's address range check respectively.
Extend struct stratix10_svc_data_mem with dma_addr, and
struct stratix10_svc_controller with use_dma_mem and dma_addr_offset.
Update allocate/free and svc_thread_cmd_data_claim() for the DMA path.
Wire the Agilex5 path in probe: require an IOMMU domain for
intel,agilex5-svc, bypass the SDM address remapper via
INTEL_SIP_SMC_SDM_REMAPPER_CONFIG, call svc_setup_dma_memory() to set
the 29-bit DMA mask, select the DMA path through stratix10_svc_pdata,
register a devm cleanup for leaked buffers, and guard err_destroy_pool
against a NULL genpool.

agilex and stratix10
On Agilex7 and Stratix10 SoCs, secondary CPUs must be offlined before
a warm reboot to ensure a clean PSCI state. Agilex5 warm reset is a
SDM-owned HPS reset that holds secondaries in the new reset-release until
ATF releases them, so the secondary cores dont have to be put offline
first. Register a reboot notifier that calls remove_cpu() on each
secondary CPU when SYS_RESTART is triggered in REBOOT_WARM mode.
A snapshot of cpu_online_mask is taken before the loop since remove_cpu()
modifies the mask as CPUs go down. CPU 0 is excluded as it is typically
not hotpluggable. Failures are logged and the loop continues so the
reboot is not blocked by a single CPU that refuses to offline.
The of_device_id table carries a per-compatible pdata flag to enable the
notifier only on platforms that need it; Agilex5 leaves the flag unset.
The notifier is unregistered at the start of remove(), before async
channel teardown, to prevent a reboot notification from racing with
driver shutdown.
