firmware: cs_dsp: test_bin_error: Fix uninitialized data used as fw version
Call cs_dsp_mock_xm_header_get_fw_version() to get the firmware version
from the dummy XM header data in cs_dsp_bin_err_test_common_init().
Make the same change to cs_dsp_bin_test_common_init() and remove the
cs_dsp_mock_xm_header_get_fw_version_from_regmap() function.
The code in cs_dsp_test_bin.c was correctly calling
cs_dsp_mock_xm_header_get_fw_version_from_regmap() to fetch the fw version
from a dummy header it wrote to XM registers. However in
cs_dsp_test_bin_error.c the test doesn't stuff a dummy header into XM, it
populates it the normal way using a wmfw file. It should have called
cs_dsp_mock_xm_header_get_fw_version() to get the data from its blob
buffer, but was calling cs_dsp_mock_xm_header_get_fw_version_from_regmap().
As nothing had been written to the registers this returned the value of
uninitialized data.
The only other use of cs_dsp_mock_xm_header_get_fw_version_from_regmap()
was cs_dsp_test_bin.c, but it doesn't need to use it. It already has a
blob buffer containing the dummy XM header so it can use
cs_dsp_mock_xm_header_get_fw_version() to read from that.

ARM:
* Rework heuristics for resolving the fault IPA (HPFAR_EL2 v. re-walk
stage-1 page tables) to align with the architecture. This avoids
possibly taking an SEA at EL2 on the page table walk or using an
architecturally UNKNOWN fault IPA.
* Use acquire/release semantics in the KVM FF-A proxy to avoid reading
a stale value for the FF-A version.
* Fix KVM guest driver to match PV CPUID hypercall ABI.
* Use Inner Shareable Normal Write-Back mappings at stage-1 in KVM
selftests, which is the only memory type for which atomic
instructions are architecturally guaranteed to work.
s390:
* Don't use %pK for debug printing and tracepoints.
x86:
* Use a separate subclass when acquiring KVM's per-CPU posted interrupts
wakeup lock in the scheduled out path, i.e. when adding a vCPU on
the list of vCPUs to wake, to workaround a false positive deadlock.
The schedule out code runs with a scheduler lock that the wakeup
handler takes in the opposite order; but it does so with IRQs disabled
and cannot run concurrently with a wakeup.
* Explicitly zero-initialize on-stack CPUID unions
* Allow building irqbypass.ko as as module when kvm.ko is a module
* Wrap relatively expensive sanity check with KVM_PROVE_MMU
* Acquire SRCU in KVM_GET_MP_STATE to protect guest memory accesses
selftests:
* Add more scenarios to the MONITOR/MWAIT test.
* Add option to rseq test to override /dev/cpu_dma_latency
* Bring list of exit reasons up to date
* Cleanup Makefile to list once tests that are valid on all architectures

* Documentation fixes

Merge tag 'cxl-for-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull Compute Express Link (CXL) updates from Dave Jiang:
- Add support for Global Persistent Flush (GPF)
- Cleanup of DPA partition metadata handling:
- Remove the CXL_DECODER_MIXED enum that's not needed anymore
- Introduce helpers to access resource and perf meta data
- Introduce 'struct cxl_dpa_partition' and 'struct cxl_range_info'
- Make cxl_dpa_alloc() DPA partition number agnostic
- Remove cxl_decoder_mode
- Cleanup partition size and perf helpers
- Remove unused CXL partition values
- Add logging support for CXL CPER endpoint and port protocol errors:
- Prefix protocol error struct and function names with cxl_
- Move protocol error definitions and structures to a common location
- Remove drivers/firmware/efi/cper_cxl.h to include/linux/cper.h
- Add support in GHES to process CXL CPER protocol errors
- Process CXL CPER protocol errors
- Add trace logging for CXL PCIe port RAS errors
- Remove redundant gp_port init
- Add validation of cxl device serial number
- CXL ABI documentation updates/fixups
- A series that uses guard() to clean up open coded mutex lockings and
remove gotos for error handling.
- Some followup patches to support dirty shutdown accounting:
- Add helper to retrieve DVSEC offset for dirty shutdown registers
- Rename cxl_get_dirty_shutdown() to cxl_arm_dirty_shutdown()
- Add support for dirty shutdown count via sysfs
- cxl_test support for dirty shutdown
- A series to support CXL mailbox Features commands.

commands. It's also in preparation for CXL fwctl support to utilize
the CXL Features. The commands include "Get Supported Features", "Get
Feature", and "Set Feature".
- A series to support extended linear cache support described by the
ACPI HMAT table.
The addition helps enumerate the cache and also provides additional
RAS reporting support for configuration with extended linear cache.
(and related fixes for the series).

Driver core updates for 6.15-rc1
Here is the big set of driver core updates for 6.15-rc1. Lots of stuff
happened this development cycle, including:
- kernfs scaling changes to make it even faster thanks to rcu
- bin_attribute constify work in many subsystems
- faux bus minor tweaks for the rust bindings
- rust binding updates for driver core, pci, and platform busses,
making more functionaliy available to rust drivers. These are all
due to people actually trying to use the bindings that were in 6.14.
- make Rafael and Danilo full co-maintainers of the driver core
codebase
- other minor fixes and updates.
This has been in linux-next for a while now, with the only reported
issue being some merge conflicts with the rust tree. Depending on which
tree you pull first, you will have conflicts in one of them. The merge
resolution has been in linux-next as an example of what to do, or can be
found here:

sound updates for 6.15-rc1
We've received lots of commits at this time, as a result of various
cleanup and refactoring works as well as a few new drivers and the
generic SoundWire support. Most of changes are device-specific,
little about the core changes. Some highlights below:
Core:
* A couple of (rather minor) race fixes in ALSA sequencer code
* A regression fix in ALSA timer code that may lead to a deadlock
ASoC:
* A large series of code conversion to use modern terminology for the
clocking configuration
* Conversions of PM ops with the modern macros in all ASoC drivers
* Clarification of the control operations
* Prepartory work for more generic SoundWire SCDA controls
* Support for AMD ACP 7.x, AWINC WM88166, Everest ES8388, Intel AVS
PEAKVOL and GAIN DSP modules Mediatek MT8188 DMIC, NXP i.MX95,
nVidia Tegra interconnects, Rockchip RK3588 S/PDIF, Texas
Instruments SN012776 and TAS5770L, and Wolfson WM8904 DMICs
Others:
* Conversions of PM ops with the modern macros in the rest drivers
* USB-audio quirks and fixes for Presonus Studio, DJM-A9, CME
* HD-audio quirks and fixes ASUS, HP, Lenovo, and others
Note that the PR contains some changes from the tip tree for AMD code,
and it might give some merge conflict due to the rebase afterwards.

ARM:
* Nested virtualization support for VGICv3, giving the nested
hypervisor control of the VGIC hardware when running an L2 VM
* Removal of 'late' nested virtualization feature register masking,
making the supported feature set directly visible to userspace
* Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers
* Paravirtual interface for discovering the set of CPU implementations
where a VM may run, addressing a longstanding issue of guest CPU
errata awareness in big-little systems and cross-implementation VM
migration
* Userspace control of the registers responsible for identifying a
particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
allowing VMs to be migrated cross-implementation
* pKVM updates, including support for tracking stage-2 page table
allocations in the protected hypervisor in the 'SecPageTable' stat
* Fixes to vPMU, ensuring that userspace updates to the vPMU after
KVM_RUN are reflected into the backing perf events
LoongArch:
* Remove unnecessary header include path
* Assume constant PGD during VM context switch
* Add perf events support for guest VM
RISC-V:
* Disable the kernel perf counter during configure
* KVM selftests improvements for PMU
* Fix warning at the time of KVM module removal
x86:
* Add support for aging of SPTEs without holding mmu_lock. Not taking mmu_lock
allows multiple aging actions to run in parallel, and more importantly avoids
stalling vCPUs. This includes an implementation of per-rmap-entry locking;
aging the gfn is done with only a per-rmap single-bin spinlock taken, whereas
locking an rmap for write requires taking both the per-rmap spinlock and
the mmu_lock.
Note that this decreases slightly the accuracy of accessed-page information,
because changes to the SPTE outside aging might not use atomic operations
even if they could race against a clear of the Accessed bit. This is
deliberate because KVM and mm/ tolerate false positives/negatives for
accessed information, and testing has shown that reducing the latency of
aging is far more beneficial to overall system performance than providing
"perfect" young/old information.
* Defer runtime CPUID updates until KVM emulates a CPUID instruction, to
coalesce updates when multiple pieces of vCPU state are changing, e.g. as
part of a nested transition.
* Fix a variety of nested emulation bugs, and add VMX support for synthesizing
nested VM-Exit on interception (instead of injecting #UD into L2).
* Drop "support" for async page faults for protected guests that do not set
SEND_ALWAYS (i.e. that only want async page faults at CPL3)
* Bring a bit of sanity to x86's VM teardown code, which has accumulated
a lot of cruft over the years. Particularly, destroy vCPUs before
the MMU, despite the latter being a VM-wide operation.
* Add common secure TSC infrastructure for use within SNP and in the
future TDX
* Block KVM_CAP_SYNC_REGS if guest state is protected. It does not make
sense to use the capability if the relevant registers are not
available for reading or writing.
* Don't take kvm->lock when iterating over vCPUs in the suspend notifier to
fix a largely theoretical deadlock.
* Use the vCPU's actual Xen PV clock information when starting the Xen timer,
as the cached state in arch.hv_clock can be stale/bogus.
* Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across different
PV clocks; restrict PVCLOCK_GUEST_STOPPED to kvmclock, as KVM's suspend
notifier only accounts for kvmclock, and there's no evidence that the
flag is actually supported by Xen guests.
* Clean up the per-vCPU "cache" of its reference pvclock, and instead only
track the vCPU's TSC scaling (multipler+shift) metadata (which is moderately
expensive to compute, and rarely changes for modern setups).
* Don't write to the Xen hypercall page on MSR writes that are initiated by
the host (userspace or KVM) to fix a class of bugs where KVM can write to
guest memory at unexpected times, e.g. during vCPU creation if userspace has
set the Xen hypercall MSR index to collide with an MSR that KVM emulates.
* Restrict the Xen hypercall MSR index to the unofficial synthetic range to
reduce the set of possible collisions with MSRs that are emulated by KVM
(collisions can still happen as KVM emulates Hyper-V MSRs, which also reside
in the synthetic range).
* Clean up and optimize KVM's handling of Xen MSR writes and xen_hvm_config.
* Update Xen TSC leaves during CPUID emulation instead of modifying the CPUID
entries when updating PV clocks; there is no guarantee PV clocks will be
updated between TSC frequency changes and CPUID emulation, and guest reads
of the TSC leaves should be rare, i.e. are not a hot path.
x86 (Intel):
* Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and thus
modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1.
* Pass XFD_ERR as the payload when injecting #NM, as a preparatory step
for upcoming FRED virtualization support.
* Decouple the EPT entry RWX protection bit macros from the EPT Violation
bits, both as a general cleanup and in anticipation of adding support for
emulating Mode-Based Execution Control (MBEC).
* Reject KVM_RUN if userspace manages to gain control and stuff invalid guest
state while KVM is in the middle of emulating nested VM-Enter.
* Add a macro to handle KVM's sanity checks on entry/exit VMCS control pairs
in anticipation of adding sanity checks for secondary exit controls (the
primary field is out of bits).
x86 (AMD):
* Ensure the PSP driver is initialized when both the PSP and KVM modules are
built-in (the initcall framework doesn't handle dependencies).
* Use long-term pins when registering encrypted memory regions, so that the
pages are migrated out of MIGRATE_CMA/ZONE_MOVABLE and don't lead to
excessive fragmentation.
* Add macros and helpers for setting GHCB return/error codes.
* Add support for Idle HLT interception, which elides interception if the vCPU
has a pending, unmasked virtual IRQ when HLT is executed.
* Fix a bug in INVPCID emulation where KVM fails to check for a non-canonical
address.
* Don't attempt VMRUN for SEV-ES+ guests if the vCPU's VMSA is invalid, e.g.
because the vCPU was "destroyed" via SNP's AP Creation hypercall.
* Reject SNP AP Creation if the requested SEV features for the vCPU don't
match the VM's configured set of features.
Selftests:
* Fix again the Intel PMU counters test; add a data load and do CLFLUSH{OPT} on the data
instead of executing code. The theory is that modern Intel CPUs have
learned new code prefetching tricks that bypass the PMU counters.
* Fix a flaw in the Intel PMU counters test where it asserts that an event is
counting correctly without actually knowing what the event counts on the
underlying hardware.
* Fix a variety of flaws, bugs, and false failures/passes dirty_log_test, and
improve its coverage by collecting all dirty entries on each iteration.
* Fix a few minor bugs related to handling of stats FDs.
* Add infrastructure to make vCPU and VM stats FDs available to tests by
default (open the FDs during VM/vCPU creation).
* Relax an assertion on the number of HLT exits in the xAPIC IPI test when
running on a CPU that supports AMD's Idle HLT (which elides interception of
HLT if a virtual IRQ is pending and unmasked).

firmware: cs_dsp: Ensure cs_dsp_load[_coeff]() returns 0 on success
Set ret = 0 on successful completion of the processing loop in
cs_dsp_load() and cs_dsp_load_coeff() to ensure that the function
returns 0 on success.
All normal firmware files will have at least one data block, and
processing this block will set ret == 0, from the result of either
regmap_raw_write() or cs_dsp_parse_coeff().
The kunit tests create a dummy firmware file that contains only the
header, without any data blocks. This gives cs_dsp a file to "load"
that will not cause any side-effects. As there aren't any data blocks,
the processing loop will not set ret == 0.
Originally there was a line after the processing loop:
ret = regmap_async_complete(regmap);
which would set ret == 0 before the function returned.

efi/libstub: Avoid legacy decompressor zlib/zstd wrappers
Remove EFI zboot's dependency on the decompression wrappers used by the legacy decompressor boot code, which can only process the input in one go, and this will not work for upcoming support for embedded ELF images. They also do some odd things like providing a barebones malloc() implementation, which is not needed in a hosted environment such as the EFI boot services. So instead, implement GZIP deflate and ZSTD decompression in terms of the underlying libraries. Support for other compression algoritms has already been dropped.

efi/libstub: Avoid physical address 0x0 when doing random allocation
Ben reports spurious EFI zboot failures on a system where physical RAM starts at 0x0. When doing random memory allocation from the EFI stub on such a platform, a random seed of 0x0 (which means no entropy source is available) will result in the allocation to be placed at address 0x0 if sufficient space is available. When this allocation is subsequently passed on to the decompression code, the 0x0 address is mistaken for NULL and the code complains and gives up. So avoid address 0x0 when doing random allocation, and set the minimum address to the minimum alignment.

firmware: thead: Add AON firmware protocol driver
The T-Head TH1520 SoC uses an E902 co-processor running Always-On (AON) firmware to manage power, clock, and other system resources [1]. This patch introduces a driver implementing the AON firmware protocol, allowing the Linux kernel to communicate with the firmware via mailbox channels. Through an RPC-based interface, the kernel can initiate power state transitions, update resource configurations, and perform other AON-related tasks.

efi/libstub: Avoid CopyMem/SetMem EFI services after ExitBootServices
Given that memset/memcpy are intrinsics, the compiler might insert calls to these routines unexpectedly, including in code that executes after ExitBootServices(). In this case, the respective boot services are no longer accessible, and calling them will cause a crash. So fall back to a bytewise copy/store if this happens to occur, even though no such occurrences are known to exist in the kernel currently. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |

firmware: arm_scmi: use ioread64() instead of ioread64_hi_lo()
The scmi_common_fastchannel_db_ring() function calls either ioread64()
or ioread64_hi_lo() depending on whether it is compiler for 32-bit
or 64-bit architectures.
The same logic is used to define ioread64() itself in the
linux/io-64-nonatomic-hi-lo.h header file, so the special case
is not really needed.
The behavior here should not change at all.

Arm FF-A updates for v6.15
This update primarily focuses on FF-A framework notification support
along with other improvements, including UUID handling enhancements
and various fixes.
1. FF-A framework notification upport
- Adds support for multiple UUIDs per partition to register individual
SRI callbacks.
- Handles Rx buffer full framework notifications and provides a general
interface for future extensions.
2. Improved multiple UUID/services per-partition handling
- Adds support for UUID passing in FFA_MSG_SEND2, improving multiple
UUID/service support in the driver.
- Introduces a helper function to check whether a partition can
receive REQUEST2 messages.
3. Partition handling generic improvements
- Implements device unregistration for better partition cleanup.
- Improves handling of the host partition presence in partition info.
4. FF-A version updates
- Upgrades the driver version to FF-A v1.2.
- Rejects major versions higher than the driver version as incompatible.
5. Big-Endian support fixes
- Fixes big-endian issues in:
__ffa_partition_info_regs_get()
__ffa_partition_info_get()
- Big-endian support is still incomplete, and only these changes can
be verified without additional application/testing updates at the
moment. We can discover all the partitions correctly with big-endian
kernel now.
6. Miscellaneous fixes
- Fixes function prototype misalignments in: sync_send_receive{,2}
- Adds explicit type casting for return values from: FFA_VERSION
and NOTIFICATION_INFO_GET
- Corrects vCPU list parsing in ffa_notification_info_get().
7. UUID management in the driver and DMA mask updates
- Replaces UUID buffer with the standard UUID format in ffa_partition_info
structure.
- Fixes a typo in some FF-A bus macros.
- Sets dma_mask for FF-A devices.
In short, this update enhances notification handling, UUID support, and
overall robustness of the FF-A driver while addressing multiple fixes
and cleanups.

Couple of updates around the flexibility in SCMI device names and addition of name, protocol id attributes and modalias for SCMI devices in the sysfs. Currently, in the scmi_protocol_device_request() function, SCMI device names ust be unique across all protocols. However, this constraint is being relaxed, allowing devices in different protocols to share the same name. The change aims to provide more flexibility in naming devices across various protocols. Two attributes: name and protocol ID is being added to the SCMI device in the sysfs along with the support for the modalias. These attributes aim to enhance device identification and management. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmfFoCcACgkQAEG6vDF+ 4piYkRAAhUsFR41gMzxKnsf1oIO3kV+6ZU8azQiHRldJEvKo8uP29XhDUYRaQau4 4ubh/4ZFR+ZMzvrVufHWklwC177bjstL075YuNF+q7U0SQ7iF1n8Fmma8JoJd/EC Tz23aW/lTuZKAFu+//YvoNnVUJZx3EB/hddcfvlQxODlwArldwblG+ftrYmGB0Cv lp5smQO1I4HnVyP3ptwIKVol5RpFnpXXflTpsCNovgfptPOGDL+HTILf4RqsWifC TxLfdgi4ciF1K3Yb9jZByBhud30JnjK/xQQTQ3I6+n66Cm29DSPTtHF5wzYalBcs ZfNiSgy8PS60WH13eGaTHYvq26BUmKu2kyi2JpdBM9DneRb16fNuv4amYrKPfbeE bYrU9Uey491zKjBnjUu1JxFvMuNzVolvztax4CAp6SbbkI22XF1OZcxt4ydVDgzQ fykc2gNr/uO/unLWnzsOYRlE/DalYsPpsuK7uNIIXPMe9JCOtOs1JOD6Pj68kNyV Gh+uCJc/eRXPg/eBchBetq9TTV+DFfMP1Rh11up0a8mrmquL/UnORORMurK922px mS6kmewHBDccwC4V4FTbaHmNivaKHhJRRNaBEV+pTkxFits2ehjfsAsxIva144Gc NLxP+Kbux5uMa/UsvXUSY+fktueh8SnmkJkUO3txixayHY3cXxs= =DMuT -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmfJyuoACgkQYKtH/8kJ UidiXQ//Qms9GfMxzJYxiJ8HCQOlvetuQJNs2u3Rhr1pWkCFxHq4sKdYpSRcwN+I MkgR4sfiMzXjqKzWl2MxJuwduZmCyo7RaHi+iyH3l/Xpwlofv+WrJkUSsTutQB+V fMwMNv8yK4Lb1Abm8JH70b0UIyXBpDmYMfkDftbj0jDV+wH+JOMaJwkVtQFA0LI+ XFIDUGV49FvZowZW1AjChdA5xtl63af9EtkEE0e6X/MFmUhg2DaX2Me1+tEchuRB LBKB49TS1v0ACT/O6u5ZBK7Mg1H4bisHMs7PpZHokU1P3FTNJqpZEESG4mE9fOG+ 5WXcvnsdL1jZjl3Mwr5szHBBlOAb8QRuQOld7I9jqSvfNrCl6jR+UQErl4UUTkJa xmwPpjl+5bzgbzVrGXNrTxiL4m/fi9HKxJiuPMny1tA3kIqHXjQPA1eXv6sUWQt0 dquCzvx5lAtHQ/m8XJ2v0ahRkWHeMyUiR1+89Zbl10gdrzDv9BfNRIvsYpiw3xRr 4WEK8XBZuCBaJus3lOt72mnPJxfNGMJk1CWp0V44jHZwBxAPJHARSEpop0azIYFK 5tKUeB/2EB5Ryh13ufdc9uXz60lf6cb2MbcfRm9IPpzQxmZ4csM2aZ5yrt3C/Y81 /NS24mV6aiATl9p1o71u8d9JZbeaWk7ogSExgrPQgChmLIE9eYQ= =cVvD -----END PGP SIGNATURE----- Merge tag 'scmi-updates-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.15 Couple of updates around the flexibility in SCMI device names and addition of name, protocol id attributes and modalias for SCMI devices in the sysfs.

Arm SMCCC update for v6.15
Just a single update introducing the support for the optional SOC_ID name string from the Arm SMCCC v1.6 specification. If the SOC_ID name string is implemented, the machine field of the SoC Device Attributes will reflect it. The original intent of SOC_ID was to provide a JEP-106 code for the SiP and the SoC revision to uniquely identify the SoC. However, there has been a request to add this optional name so that SoC firmware can directly provide the SoC name to the OS. This change avoids the need for frequent updates to various tools that would otherwise require maintaining hardcoded model/machine name tables for new SoCs. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmfG1J8ACgkQAEG6vDF+ 4phrQg//St4RPwFt1WngjQ2ioZzyiBXO3/eh3nnMiW+5fNvVuq2azldTsdLW3lO5 kqP2ONiTu+LI7a2OXJzbLVTVwyoPg/iTgkqvGPuBiZeVHE1+WCY2lWbySQaKULfJ ViCwRmBF2Pmu7AsC7aBGqbRy1njBESFkybOfT8MAPt5/kvJX7n1V09uHnHNQwB2f f0g5UcamsPLyZQN9j8kyNJNsz/pVKTFG+ooKvnLGDeU82pNygn7Q+7ho79ICDGz4 //9bAgA73xQ685jxWCGgeXDdvexW6HS7F5zyDW1FDPAq4ABLzZY/QpWyaGKF8AcE /BQR0Awzmd4v7jDh1tl0TfZ82jCdUu2wE++SdyK227IIZR/8n7xDOaBpRjWXUCJI seD4NL/obMEMSkikgRWBy10mumqjGYFlxsWy7IHh/9y+zU3y1w2Ed3nE2n/5Ekrx XNa0x9YjfkCwwc8MYacCfXR8n6UHBFRlSQ5oOH3Ai725eTAR4pIojCOFQrQlm6Vf 5ZmqSbPYy7WgC6Rzon/YRAc/0L4qKNkfkazQFQ0xHJ9asnRLrkxh2o2OC3bwyuru 82BNHsGg1Gn3FcvLmNnsbrHo+GsPqbeezciLtLw7rurJir6I24kyl6SLjHDBgCSL I7un2GYwOXca9WhLpkTRxudgZ0ZxEWFRjJnXS3b7H/okwZ1050w= =/iKV -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmfJynoACgkQYKtH/8kJ UidLdg//Uv+QN8hSCah0apoWl+oNPmiFb/1vRptR/Jt++uVKQ7MIR4oFbjR5szOw 3mJeCftsdSLB4XYzZlnx2f/PmsQjffs6CkFdzLDveF8aKk1rmhra+9ZDwz8oPbP/ drLVPcc6UMtDfZigYau/8cr70lhGSI5z4S0SHW1wgoroTIFJhl4QluQjmb5Ruryt ARNDjoGM+PjyW6QZQgAk2oQVObZB5gYU18jQRm/R3Pj7lhJt6+lG1wF+ZK6ksbYB 3WhzzgQ4BOfXXV3NL+bhb4Ut7TFmyWzT/aeZpYbkIn+sBcu/9CTf2L7MYcRC3t7q 8zS6sl1oGRc4t/zQxqupwKwrCE2oV4UcILhChCKfOJ1oBa9AYLWVe6ZdU+853izt kRt8NkA8N74dmebbg4B8MOkSjCBc3WjyjXpXlyQsxM+BPsDmTf8JDVsAe9D803X6 4RRK9qxo+GfjWe3mlqL5y3t0D82XSyzOTZ8GaXr+8YYsxoMjrZWOu6G2nZtj0NtY 6vmKCo8NeRDCqW68xkyA/qfA51TvWM6dE1ybeGWh8+vUMhc5FdzhgX0LPE14rAdC uNY5X0SXVGbRSSdrUwwv87KnbUl2XcjwKTPbOPmWxnek/vfgvq4pLaNMituVVGGc aaLvcISDu5UmYGwxDcXouhD7T44aCz6w17W2R38kJUmlTlC+YDo= =tny0 -----END PGP SIGNATURE----- Merge tag 'smccc-update-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SMCCC update for v6.15 Just a single update introducing the support for the optional SOC_ID name string from the Arm SMCCC v1.6 specification.

firmware: smccc: Support optional Arm SMCCC SOC_ID name
Issue Number 1.6 of the Arm SMC Calling Convention introduces an optional SOC_ID name string. If implemented, point the 'machine' field of the SoC Device Attributes at this string so that it will appear under /sys/bus/soc/devices/soc0/machine. On Arm SMC compliant SoCs, this will allow things like 'lscpu' to eventually get a SoC provider model name from there rather than each tool/utility needing to get a possibly inconsistent, obsolete, or incorrect model/machine name from its own hardcoded model/machine name table.

Pull EFI fixes from Ard Biesheuvel:
"Another couple of EFI fixes for v6.14.
Only James's patch stands out, as it implements a workaround for odd
behavior in fwupd in user space, which creates EFI variables by
touching a file in efivarfs, clearing the immutable bit (which gets
set automatically for $reasons) and then opening it again for writing,
none of which is really necessary.
The fwupd author and LVFS maintainer is already rolling out a fix for
this on the fwupd side, and suggested that the workaround in this PR
could be backed out again during the next cycle.
(There is a semantic mismatch in efivarfs where some essential
variable attributes are stored in the first 4 bytes of the file, and
so zero length files cannot exist, as they cannot be written back to
the underlying variable store. So now, they are dropped once the last
reference is released.)

- Fix CPER error record parsing bugs
- Fix a couple of efivarfs issues that were introduced in the merge

- Fix an issue in the early remapping code of the MOKvar table"
