a812b09a6b dt-bindings: pci: spacemit: Introduce PCIe host controller
Add the Devicetree binding for the PCIe Root Complex found on the SpacemiT
K1 SoC.  This Root Complex is derived from the Synopsys Designware PCIe IP.
It supports up to three PCIe ports operating at PCIe link speed up to 5
GT/sec. One of the ports uses a combo PHY, which is typically used to
support a USB3 port.

Pull RTC updates from Alexandre Belloni:
 "This cycle, we have a new RTC driver, for the SpacemiT P1. The optee
  driver gets alarm support. We also get a fix for a race condition that
  was fairly rare unless while stress testing the alarms.

  Subsystem:
   - Fix race when setting alarm
   - Ensure alarm irq is enabled when UIE is enabled
   - remove unneeded 'fast_io' parameter in regmap_config

  New driver:
   - SpacemiT P1 RTC

  Drivers:
   - efi: Remove wakeup functionality
   - optee: add alarms support
   - s3c: Drop support for S3C2410
   - zynqmp: Restore alarm functionality after kexec transition"

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

 - Other smaller cleanups and touchups all over the place

Pull more power management updates from Rafael Wysocki:
 "These are cpufreq fixes and cleanups on top of the material merged
  previously, a power management core code fix and updates of the
  runtime PM framework including unit tests, documentation updates and
  introduction of auto-cleanup macros for runtime PM "resume and get"
  and "get without resuming" operations.

  Specifics:

   - 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)

   - Make pm_runtime_put*() family of functions return 1 when the given
     device is already suspended which is consistent with the
     documentation (Brian Norris)

   - Add basic kunit tests for runtime PM API contracts and update
     return values in kerneldoc comments for the runtime PM API (Brian
     Norris, Dan Carpenter)

   - Add auto-cleanup macros for runtime PM "resume and get" and "get
     without resume" operations, use one of them in the PCI core and
     drop the existing "free" macro introduced for similar purpose, but
     somewhat cumbersome to use (Rafael Wysocki)

     those device links elsewhere (Pin-yen Lin)"

522ba450b5 Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
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"

53d4d315d4 Merge branch 'pm-cpufreq'
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)

d3e35a151a dt-bindings: mailbox: Add MT8196 GPUEB Mailbox
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.

426f4e9414 dt-bindings: mailbox: mediatek,gce-mailbox: Make clock-names optional
The GCE Mailbox needs only one clock and the clock-names can be
used only by the driver (which, for instance, does not use it),
and this is true for all of the currently supported MediaTek SoCs.

Stop requiring to specify clock-names on all non-MT8195 GCEs.

256e341706 Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
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"

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that
     take config space accessor functions.

     Implement pci_find_capability(), pci_find_ext_capability(), and
     dwc, dwc endpoint, and cadence capability search interfaces with
     them (Hans Zhang)

   - Leave parent unit address 0 in 'interrupt-map' so that when we
     build devicetree nodes to describe PCI functions that contain
     multiple peripherals, we can build this property even when
     interrupt controllers lack 'reg' properties (Lorenzo Pieralisi)

   - Add a Xeon 6 quirk to disable Extended Tags and limit Max Read
     Request Size to 128B to avoid a performance issue (Ilpo Järvinen)

   - Add sysfs 'serial_number' file to expose the Device Serial Number
     (Matthew Wood)

   - Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)

  Resource management:

   - Align m68k pcibios_enable_device() with other arches (Ilpo
     Järvinen)

   - Remove sparc pcibios_enable_device() implementations that don't do
     anything beyond what pci_enable_resources() does (Ilpo Järvinen)

   - 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)"

Pull Char/Misc/IIO/Binder updates from Greg KH:
 "Here is the big set of char/misc/iio and other driver subsystem
  changes for 6.18-rc1.

  Loads of different stuff in here, it was a busy development cycle in
  lots of different subsystems, with over 27k new lines added to the
  tree.

  Included in here are:

   - IIO updates including new drivers, reworking of existing apis, and
     other goodness in the sensor subsystems

   - MEI driver updates and additions

   - NVMEM driver updates

   - slimbus removal for an unused driver and some other minor updates

   - coresight driver updates and additions

   - MHI driver updates

   - comedi driver updates and fixes

   - extcon driver updates

   - interconnect driver additions

   - eeprom driver updates and fixes

   - minor UIO driver updates

   - tiny W1 driver updates

  But the majority of new code is in the rust bindings and additions,
  which includes:

   - misc driver rust binding updates for read/write support, we can now
     write "normal" misc drivers in rust fully, and the sample driver
     shows how this can be done.

   - Initial framework for USB driver rust bindings, which are disabled
     for now in the build, due to limited support, but coming in through
     this tree due to dependencies on other rust binding changes that
     were in here. I'll be enabling these back on in the build in the
     usb.git tree after -rc1 is out so that developers can continue to
     work on these in linux-next over the next development cycle.

   - Android Binder driver implemented in Rust.

     This is the big one, and was driving a huge majority of the rust
     binding work over the past years. Right now there are two binder
     drivers in the kernel, selected only at build time as to which one
     to use as binder wants to be included in the system at boot time.

     want the C code to be removed from the tree, but it will take a few

   mailbox between S-mode operating systems (e.g., Linux) and M-mode
   firmware (e.g., OpenSBI). It is part of this PR since one of its use
   cases is to enable M-mode firmware to act as a single RPMI client for
   all RPMI activity on a core (including S-mode RPMI activity).
   Includes a mailbox driver.

 - Some ACPI-related updates to enable the use of RPMI and MPXY.

 - The addition of Linux-wide memcpy_{from,to}_le32() static inline
   functions, for RPMI use.

 - An ACPI Kconfig change to enable boot logos on any ACPI-using
   architecture (including RISC-V)

 - A RISC-V defconfig change to add GPIO keyboard and event device
   support, for front panel shutdown or reboot buttons

Pull x86 TDX updates from Dave Hansen:
 "The biggest change here is making TDX and kexec play nicely together.

  Before this, the memory encryption hardware (which doesn't respect
  cache coherency) could write back old cachelines on top of data in the
  new kernel, so kexec and TDX were made mutually exclusive. This
  removes the limitation.

  There is also some work to tighten up a hardware bug workaround and
  some MAINTAINERS updates.

   - Make TDX and kexec work together

    - Skip TDX bug workaround when the bug is not present

    - Update maintainers entries"
