Pull more x86 updates from Borislav Petkov:
- Remove a bunch of asm implementing condition flags testing in KVM's
emulator in favor of int3_emulate_jcc() which is written in C
- Replace KVM fastops with C-based stubs which avoids problems with the
fastop infra related to latter not adhering to the C ABI due to their
special calling convention and, more importantly, bypassing compiler
control-flow integrity checking because they're written in asm
- Remove wrongly used static branches and other ugliness accumulated
over time in hyperv's hypercall implementation with a proper static
function call to the correct hypervisor call variant
- Add some fixes and modifications to allow running FRED-enabled
kernels in KVM even on non-FRED hardware
- Add kCFI improvements like validating indirect calls and prepare for
enabling kCFI with GCC. Add cmdline params documentation and other
code cleanups
- Use the single-byte 0xd6 insn as the official #UD single-byte
undefined opcode instruction as agreed upon by both x86 vendors

Add a guest_memfd flag to allow userspace to state that the underlying
memory should be configured to be initialized as shared, and reject user
page faults if the guest_memfd instance's memory isn't shared. Because
KVM doesn't yet support in-place private<=>shared conversions, all
guest_memfd memory effectively follows the initial state.
Alternatively, KVM could deduce the initial state based on MMAP, which for
all intents and purposes is what KVM currently does. However, implicitly
deriving the default state based on MMAP will result in a messy ABI when
support for in-place conversions is added.
For x86 CoCo VMs, which don't yet support MMAP, memory is currently private
by default (otherwise the memory would be unusable). If MMAP implies
memory is shared by default, then the default state for CoCo VMs will vary
based on MMAP, and from userspace's perspective, will change when in-place
conversion support is added. I.e. to maintain guest<=>host ABI, userspace
would need to immediately convert all memory from shared=>private, which
is both ugly and inefficient. The inefficiency could be avoided by adding
a flag to state that memory is _private_ by default, irrespective of MMAP,
but that would lead to an equally messy and hard to document ABI.
Bite the bullet and immediately add a flag to control the default state so
that the effective behavior is explicit and straightforward.

Rework the not-yet-released KVM_CAP_GUEST_MEMFD_MMAP into a more generic
KVM_CAP_GUEST_MEMFD_FLAGS capability so that adding new flags doesn't
require a new capability, and so that developers aren't tempted to bundle
multiple flags into a single capability.
Note, kvm_vm_ioctl_check_extension_generic() can only return a 32-bit
value, but that limitation can be easily circumvented by adding e.g.
KVM_CAP_GUEST_MEMFD_FLAGS2 in the unlikely event guest_memfd supports more
than 32 flags.

Some of the details about how directory hash trees work were confusing or
outright wrong, this patch should fix those.
A note on dx_tail's dt_reserved member, as far as I can tell the kernel
never sets this explicitly, so its content is apparently left-overs from
what was there before (for the dx_root I've seen remnants of a
ext4_dir_entry_tail struct from when the dir was not yet a hash dir).

Pull clk updates from Stephen Boyd:
"There's a bunch of patches here across drivers/clk/ to migrate drivers
to use struct clk_ops::determine_rate() instead of the round_rate()
one so that we can remove the round_rate clk_op entirely. Brian has
taken up that task which nobody else has wanted to do for close to a
decade. Thanks Brian!
This is all prerequisite work to get to the real task of improving the
clk rate setting process. Once we have determine_rate() used
everywhere, we'll be able to do things like chain the rate request
structs in linked lists to order the rate setting operations or add
more parameters without having to change every clk driver in
existence. It's also nice to not have multiple ways to do something
which just causes confusion for clk driver authors. Overall I'm glad
this is getting done.
Beyond this change we also have a tweak to the clk_lookup() function
in the core framework to use hashing on the clk name instead of a clk
tree walk with string comparisons. We _still_ rely on the clk name to
be unique, because historically we've used globally unique strings to
describe the clk tree topology. This tree walk becomes increasingly
slow as more clks are added to the system. Searching from the roots
for a duplicate is simple but pretty dumb and it wastes boot time so
we're using a hash table as an improvement. Ideally we wouldn't rely
on the strings to be unique at all, relegating them to simply debug
information, but that is future work that will likely require some
sort of Kconfig knob indicating strings aren't used for topology
description.
Outside of the core framework changes we have the usual new SoC
support and fixes to clk drivers for things that were discovered once
the clks were used by consumer drivers. Nothing in particular is
jumping out at me in the "misc" pile, except maybe the Amlogic driver
that has gone through a refactoring. That series got a fix from
testing in -next though so it seems likely that things have been
getting good test coverage for a couple weeks already"

Merge cpufreq fixes and cleanups, mostly on top of those fixes, for
6.18-rc1:
- Make cpufreq drivers setting the default CPU transition latency to
CPUFREQ_ETERNAL specify a proper default transition latency value
instead which addresses a regression introduced during the 6.6 cycle
that broke CPUFREQ_ETERNAL handling (Rafael Wysocki)
- Make the cpufreq CPPC driver use a proper transition delay value
when CPUFREQ_ETERNAL is returned by cppc_get_transition_latency() to
indicate an error condition (Rafael Wysocki)
- Make cppc_get_transition_latency() return a negative error code to
indicate error conditions instead of using CPUFREQ_ETERNAL for this
purpose and drop CPUFREQ_ETERNAL that has no other users (Rafael
Wysocki, Gopi Krishna Menon)
- Fix device leak in the mediatek cpufreq driver (Johan Hovold)
- Set target frequency on all CPUs sharing a policy during frequency
updates in the tegra186 cpufreq driver and make it initialize all
cores to max frequencies (Aaron Kling)
- Rust cpufreq helper cleanup (Thorsten Blum)

The MediaTek MT8196 SoC includes an embedded MCU referred to as "GPUEB",
acting as glue logic to control power and frequency of the Mali GPU.
This MCU runs special-purpose firmware for this use, and the main
application processor communicates with it through a mailbox.
Add a binding that describes this mailbox.

Pull x86 kvm updates from Paolo Bonzini:
"Generic:
- Rework almost all of KVM's exports to expose symbols only to KVM's
x86 vendor modules (kvm-{amd,intel}.ko and PPC's kvm-{pr,hv}.ko
x86:
- Rework almost all of KVM x86's exports to expose symbols only to
KVM's vendor modules, i.e. to kvm-{amd,intel}.ko
- Add support for virtualizing Control-flow Enforcement Technology
(CET) on Intel (Shadow Stacks and Indirect Branch Tracking) and AMD
(Shadow Stacks).
It is worth noting that while SHSTK and IBT can be enabled
separately in CPUID, it is not really possible to virtualize them
separately. Therefore, Intel processors will really allow both
SHSTK and IBT under the hood if either is made visible in the
guest's CPUID. The alternative would be to intercept
XSAVES/XRSTORS, which is not feasible for performance reasons
- Fix a variety of fuzzing WARNs all caused by checking L1 intercepts
when completing userspace I/O. KVM has already committed to
allowing L2 to to perform I/O at that point
- Emulate PERF_CNTR_GLOBAL_STATUS_SET for PerfMonV2 guests, as the
MSR is supposed to exist for v2 PMUs
- Allow Centaur CPU leaves (base 0xC000_0000) for Zhaoxin CPUs
- Add support for the immediate forms of RDMSR and WRMSRNS, sans full
emulator support (KVM should never need to emulate the MSRs outside
of forced emulation and other contrived testing scenarios)
- Clean up the MSR APIs in preparation for CET and FRED
virtualization, as well as mediated vPMU support
- Clean up a pile of PMU code in anticipation of adding support for
mediated vPMUs
- Reject in-kernel IOAPIC/PIT for TDX VMs, as KVM can't obtain EOI
vmexits needed to faithfully emulate an I/O APIC for such guests
- Many cleanups and minor fixes
- Recover possible NX huge pages within the TDP MMU under read lock
to reduce guest jitter when restoring NX huge pages
- Return -EAGAIN during prefault if userspace concurrently
deletes/moves the relevant memslot, to fix an issue where
prefaulting could deadlock with the memslot update
x86 (AMD):
- Enable AVIC by default for Zen4+ if x2AVIC (and other prereqs) is
supported
- Require a minimum GHCB version of 2 when starting SEV-SNP guests
via KVM_SEV_INIT2 so that invalid GHCB versions result in immediate
errors instead of latent guest failures
- Add support for SEV-SNP's CipherText Hiding, an opt-in feature that
prevents unauthorized CPU accesses from reading the ciphertext of
SNP guest private memory, e.g. to attempt an offline attack. This
feature splits the shared SEV-ES/SEV-SNP ASID space into separate
ranges for SEV-ES and SEV-SNP guests, therefore a new module
parameter is needed to control the number of ASIDs that can be used
for VMs with CipherText Hiding vs. how many can be used to run
SEV-ES guests
- Add support for Secure TSC for SEV-SNP guests, which prevents the
untrusted host from tampering with the guest's TSC frequency, while
still allowing the the VMM to configure the guest's TSC frequency
prior to launch
- Validate the XCR0 provided by the guest (via the GHCB) to avoid
bugs resulting from bogus XCR0 values
- Save an SEV guest's policy if and only if LAUNCH_START fully
succeeds to avoid leaving behind stale state (thankfully not
consumed in KVM)
- Explicitly reject non-positive effective lengths during SNP's
LAUNCH_UPDATE instead of subtly relying on guest_memfd to deal with
them
- Reload the pre-VMRUN TSC_AUX on #VMEXIT for SEV-ES guests, not the
host's desired TSC_AUX, to fix a bug where KVM was keeping a
different vCPU's TSC_AUX in the host MSR until return to userspace
KVM (Intel):
- Preparation for FRED support
- Don't retry in TDX's anti-zero-step mitigation if the target
memslot is invalid, i.e. is being deleted or moved, to fix a
deadlock scenario similar to the aforementioned prefaulting case
- Misc bugfixes and minor cleanups"

- Remove mips pcibios_enable_resources() and use
pci_enable_resources() instead (Ilpo Järvinen)
- Clean up bridge window sizing and assignment (Ilpo Järvinen),
including:
- Leave non-claimed bridge windows disabled
- Enable bridges even if a window wasn't assigned because not all
windows are required by downstream devices
- Preserve bridge window type when releasing the resource, since
the type is needed for reassignment
- Consolidate selection of bridge windows into two new
interfaces, pbus_select_window() and
pbus_select_window_for_type(), so this is done consistently
- Compute bridge window start and end earlier to avoid logging
stale information
MSI:
- Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
Vives)
Error handling:
- Align AER with EEH by allowing drivers to request a Bus Reset on
Non-Fatal Errors (in addition to the reset on Fatal Errors that we
already do) (Lukas Wunner)
- If error recovery fails, emit FAILED_RECOVERY uevents for the
devices, not for the bridge leading to them.
This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner)
- Align AER with EEH by calling err_handler.error_detected()
callbacks to notify drivers if error recovery fails (Lukas Wunner)
- Align AER with EEH by restoring device error_state to
pci_channel_io_normal before the err_handler.slot_reset() callback.
This is earlier than before the err_handler.resume() callback
(Lukas Wunner)
- Emit a BEGIN_RECOVERY uevent when driver's
err_handler.error_detected() requests a reset, as well as when it
says recovery is complete or can be done without a reset (Niklas
Schnelle)
- Align s390 with AER and EEH by emitting uevents during error
recovery (Niklas Schnelle)
- Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the
result of err_handler.error_detected() (Niklas Schnelle)
- Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES
error information identifies a device without an AER Capability
(Breno Leitao)
- Update error decoding and TLP Log printing for new errors in
current PCIe base spec (Lukas Wunner)
- Update error recovery documentation to match the current code
and use consistent nomenclature (Lukas Wunner)
ASPM:
- Enable all ClockPM and ASPM states for devicetree platforms, since
there's typically no firmware that enables ASPM
This is a risky change that may uncover hardware or configuration
defects at boot-time rather than when users enable ASPM via sysfs
later. Booting with "pcie_aspm=off" prevents this enabling
(Manivannan Sadhasivam)
- Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)
Power management:
- If a device has already been disconnected, e.g., by a hotplug
removal, don't bother trying to resume it to D0 when detaching the
driver.
This avoids annoying "Unable to change power state from D3cold to
D0" messages (Mario Limonciello)
- Ensure devices are powered up before config reads for
'max_link_width', 'current_link_speed', 'current_link_width',
'secondary_bus_number', and 'subordinate_bus_number' sysfs files.
This prevents using invalid data (~0) in drivers or lspci and,
depending on how the PCIe controller reports errors, may avoid
error interrupts or crashes (Brian Norris)
Virtualization:
- Add rescan/remove locking when enabling/disabling SR-IOV, which
avoids list corruption on s390, where disabling SR-IOV also
generates hotplug events (Niklas Schnelle)
Peer-to-peer DMA:
- Free struct p2p_pgmap, not a member within it, in the
pci_p2pdma_add_resource() error path (Sungho Kim)
Endpoint framework:
- Document sysfs interface for BAR assignment of vNTB endpoint
functions (Jerome Brunet)
- Fix array underflow in endpoint BAR test case (Dan Carpenter)
- Skip endpoint IRQ test if the IRQ is out of range to avoid false
errors (Christian Bruel)
- Fix endpoint test case for controllers with fixed-size BARs smaller
than requested by the test (Marek Vasut)
- Restore inbound translation when disabling doorbell so the endpoint
doorbell test case can be run more than once (Niklas Cassel)
- Avoid a NULL pointer dereference when releasing DMA channels in
endpoint DMA test case (Shin'ichiro Kawasaki)
- Convert tegra194 interrupt number to MSI vector to fix endpoint
Kselftest MSI_TEST test case (Niklas Cassel)
- Reset tegra194 BARs when running in endpoint mode so the BAR tests
don't overwrite the ATU settings in BAR4 (Niklas Cassel)
- Handle errors in tegra194 BPMP transactions so we don't mistakenly
skip future PERST# assertion (Vidya Sagar)
AMD MDB PCIe controller driver:
- Update DT binding example to separate PERST# to a Root Port stanza
to make multiple Root Ports possible in the future (Sai Krishna
Musham)
- Add driver support for PERST# being described in a Root Port
stanza, falling back to the host bridge if not found there (Sai
Krishna Musham)
Freescale i.MX6 PCIe controller driver:
- Enable the 3.3V Vaux supply if available so devices can request
wakeup with either Beacon or WAKE# (Richard Zhu)
MediaTek PCIe Gen3 controller driver:
- Add optional sys clock ready time setting to avoid sys_clk_rdy
signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)
- Add DT binding and driver support for MT6991 and MT8196
(AngeloGioacchino Del Regno)
NVIDIA Tegra PCIe controller driver:
- When asserting PERST#, disable the controller instead of mistakenly
disabling the PLL twice (Nagarjuna Kristam)
- Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
Qualcomm PCIe controller driver:
- Select PCI Power Control Slot driver so slot voltage rails can be
turned on/off if described in Root Port devicetree node (Qiang Yu)
- Parse only PCI bridge child nodes in devicetree, skipping unrelated
nodes such as OPP (Operating Performance Points), which caused
probe failures (Krishna Chaitanya Chundru)
- Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)
- Consolidate Root Port 'phy' and 'reset' properties in struct
qcom_pcie_port, regardless of whether we got them from the Root
Port node or the host bridge node (Manivannan Sadhasivam)
- Fetch and map the ELBI register space in the DWC core rather than
in each driver individually (Krishna Chaitanya Chundru)
- Enable ECAM mechanism in DWC core by setting up iATU with 'CFG
Shift Feature' and use this in the qcom driver (Krishna Chaitanya
Chundru)
- Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
Chundru)
- Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
Glymur, which is compatible with X1E80100 but doesn't have the
cnoc_sf_axi clock (Qiang Yu)
Renesas R-Car PCIe controller driver:
- Fix a typo that prevented correct PHY initialization (Marek Vasut)
- Add a missing 1ms delay after PWR reset assertion as required by
the V4H manual (Marek Vasut)
- Assure reset has completed before DBI access to avoid SError (Marek
Vasut)
- Fix inverted PHY initialization check, which sometimes led to
timeouts and failure to start the controller (Marek Vasut)
- Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
regression when converting to msi_create_parent_irq_domain()
(Claudiu Beznea)
- Drop the spinlock protecting the PMSR register - it's no longer
required since pci_lock already serializes accesses (Marek Vasut)
- Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
SOPHGO PCIe controller driver:
- Check for existence of struct cdns_pcie.ops before using it to
allow Cadence drivers that don't need to supply ops (Chen Wang)
- Add DT binding and driver for the SOPHGO SG2042 PCIe controller
(Chen Wang)
STMicroelectronics STM32MP25 PCIe controller driver:
- Update pinctrl documentation of initial states and use in runtime
suspend/resume (Christian Bruel)
- Add pinctrl_pm_select_init_state() for use by stm32 driver, which
needs it during resume (Christian Bruel)
- Add devicetree bindings and drivers for the STMicroelectronics
STM32MP25 in host and endpoint modes (Christian Bruel)
Synopsys DesignWare PCIe controller driver:
- Add support for x16 in devicetree 'num-lanes' property (Konrad
Dybcio)
- Verify that if DT specifies a single IRQ for all eDMA channels, it
is named 'dma' (Niklas Cassel)
TI J721E PCIe driver:
- Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth
Vadapalli)
- Power controller off before configuring the glue layer so the
controller latches the correct values on power-on (Siddharth
Vadapalli)
TI Keystone PCIe controller driver:
- Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver
exits with error (Siddharth Vadapalli)
- Add Peripheral Virtualization Unit (PVU), which restricts DMA from
PCIe devices to specific regions of host memory, to the ti,am65
binding (Jan Kiszka)
Xilinx NWL PCIe controller driver:
- Clear bootloader E_ECAM_CONTROL before merging in the new driver
value to avoid writing invalid values (Jani Nurminen)"
