Pull kvm fixes from Paolo Bonzini:
"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
Other:
- Documentation fixes"

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.
Conversion was done with coccinelle plus manual fixups where necessary.

Pull kvm updates from Paolo Bonzini:
"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)"

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.
Commit fe08b7d5085a ("firmware: cs_dsp: Remove async regmap writes")
changed the regmap write to a normal sync write, so the call to
regmap_async_complete() wasn't necessary and was removed. It was
overlooked that the ret here wasn't only to check the result of
regmap_async_complete(), it also set the final return value of the
function.

* kvm-arm64/pv-cpuid:
: Paravirtualized implementation ID, courtesy of Shameer Kolothum
:
: Big-little has historically been a pain in the ass to virtualize. The
: implementation ID (MIDR, REVIDR, AIDR) of a vCPU can change at the whim
: of vCPU scheduling. This can be particularly annoying when the guest
: needs to know the underlying implementation to mitigate errata.
:
: "Hyperscalers" face a similar scheduling problem, where VMs may freely
: migrate between hosts in a pool of heterogenous hardware. And yes, our
: server-class friends are equally riddled with errata too.
:
: In absence of an architected solution to this wart on the ecosystem,
: introduce support for paravirtualizing the implementation exposed
: to a VM, allowing the VMM to describe the pool of implementations that a
: VM may be exposed to due to scheduling/migration.
:
: Userspace is expected to intercept and handle these hypercalls using the
: SMCCC filter UAPI, should it choose to do so.

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.

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.

channels. Through an RPC-based interface, the kernel can initiate power
state transitions, update resource configurations, and perform other
AON-related tasks.

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.

The scmi_common_fastchannel_db_ring() function calls either ioread64()

The same logic is used to define ioread64() itself in the

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.

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.
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.

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

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

Issue Number 1.6 of the Arm SMC Calling Convention introduces an optional

Device Attributes at this string so that it will appear under

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.)

mokvar: Failed to map EFI MOKvar config table pa=0x7c4c3000, size=265187.
Mapping the entire structure isn't actually necessary, as we don't ever
need more than one entry header mapped at once.
Changes efi_mokvar_table_init() to only map each entry header, not the
entire table, when determining the table size. Since we're not mapping
any data past the variable name, it also changes the code to enforce
that each variable name is NUL terminated, rather than attempting to
verify it in place.

With ARCH_K3=y we cannot enable TI_SCI_PROTOCOL=m because
ARCH_K3 selects TI_SCI_PROTOCOL.
Modify the logic to enable TI_SCI_PROTOCOL by default when ARCH_K3=y
allowing us to submit a future patch to remove select on ARCH_K3 without
breaking existing users.

Change calls to async regmap write functions to use the normal
blocking writes so that the cs35l56 driver can use spi_bus_lock() to
gain exclusive access to the SPI bus.
As this is part of a fix, it makes only the minimal change to swap the
functions to the blocking equivalents. There's no need to risk
reworking the buffer allocation logic that is now partially redundant.
The async writes are a 12-year-old workaround for inefficiency of
synchronous writes in the SPI subsystem. The SPI subsystem has since
been changed to avoid the overheads, so this workaround should not be
necessary.
The cs35l56 driver needs to use spi_bus_lock() prevent bus activity
while it is soft-resetting the cs35l56. But spi_bus_lock() is
incompatible with spi_async() calls, which will fail with -EBUSY.

The FF-A notification id list received in response to the call
FFA_NOTIFICATION_INFO_GET is encoded as: partition ID followed by 0 or
more vCPU ID. The count includes all of them.
Fix the issue by skipping the first/partition ID so that only the list
of vCPU IDs are processed correctly for a given partition ID. The first/
partition ID is read before the start of the loop.

According to the UEFI Common Platform Error Record appendix, the
processor context information structure is a variable length structure,
but "is padded with zeros if the size is not a multiple of 16 bytes".
Currently this isn't honoured, causing all but the first structure to
be garbage when printed. Thus align the size to be a multiple of 16.

The EFI mixed mode code has been decoupled from the legacy decompressor,
in order to be able to reuse it with generic EFI zboot images for x86.
Move the source file into the libstub source directory to facilitate
this.

The difference between the PE and handover entrypoints in the EFI stub
is that the former allocates a struct boot_params whereas the latter
expects one from the caller. Currently, these are two completely
separate entrypoints, duplicating some logic and both relying of
efi_exit() to return straight back to the firmware on an error.
Simplify this by making the PE entrypoint call the handover entrypoint
with NULL as the argument for the struct boot_params parameter. This
makes the code easier to follow, and removes the need to support two
different calling conventions in the mixed mode asm code.
While at it, move the assignment of boot_params_ptr into the function
that actually calls into the legacy decompressor, which is where its
value is required.
