lib/Kconfig.debug: Restrict DEBUG_INFO_SPLIT for RISC-V 
When building for ARCH=riscv using LLVM < 14, there is an error with
CONFIG_DEBUG_INFO_SPLIT=y:

  error: A dwo section may not contain relocations

This was worked around in LLVM 15 by disallowing '-gsplit-dwarf' with
'-mrelax' (the default), so CONFIG_DEBUG_INFO_SPLIT is not selectable
with newer versions of LLVM:

  $ clang --target=riscv64-linux-gnu -gsplit-dwarf -c -o /dev/null -x c /dev/null
  clang: error: -gsplit-dwarf is unsupported with RISC-V linker relaxation (-mrelax)

GCC silently had a similar issue that was resolved with GCC 12.x.
Restrict CONFIG_DEBUG_INFO_SPLIT for RISC-V when using LLVM or GCC <
12.x to avoid these known issues.

Merge patch series "RISC-V: mm: Make SV48 the default address space" 
Charlie Jenkins <charlie@rivosinc.com> says:

Make sv48 the default address space for mmap as some applications
currently depend on this assumption. Users can now select a
desired address space using a non-zero hint address to mmap. Previously,
requesting the default address space from mmap by passing zero as the hint
address would result in using the largest address space possible. Some
applications depend on empty bits in the virtual address space, like Go and
Java, so this patch provides more flexibility for application developers.

Merge patch series "riscv: Reduce ARCH_KMALLOC_MINALIGN to 8" 
Jisheng Zhang <jszhang@kernel.org> says:

Currently, riscv defines ARCH_DMA_MINALIGN as L1_CACHE_BYTES, I.E
64Bytes, if CONFIG_RISCV_DMA_NONCOHERENT=y. To support unified kernel
Image, usually we have to enable CONFIG_RISCV_DMA_NONCOHERENT, thus
it brings some bad effects to coherent platforms:

Firstly, it wastes memory, kmalloc-96, kmalloc-32, kmalloc-16 and
kmalloc-8 slab caches don't exist any more, they are replaced with
either kmalloc-128 or kmalloc-64.

Secondly, larger than necessary kmalloc aligned allocations results
in unnecessary cache/TLB pressure.

This issue also exists on arm64 platforms. From last year, Catalin
tried to solve this issue by decoupling ARCH_KMALLOC_MINALIGN from
ARCH_DMA_MINALIGN, limiting kmalloc() minimum alignment to
dma_get_cache_alignment() and replacing ARCH_KMALLOC_MINALIGN usage
in various drivers with ARCH_DMA_MINALIGN etc.[1]

One fact we can make use of for riscv: if the CPU doesn't support
ZICBOM or T-HEAD CMO, we know the platform is coherent. Based on
Catalin's work and above fact, we can easily solve the kmalloc align
issue for riscv: we can override dma_get_cache_alignment(), then let
it return ARCH_DMA_MINALIGN at the beginning and return 1 once we know
the underlying HW neither supports ZICBOM nor supports T-HEAD CMO.

So what about if the CPU supports ZICBOM or T-HEAD CMO, but all the
devices are dma coherent? Well, we use ARCH_DMA_MINALIGN as the
kmalloc minimum alignment, nothing changed in this case. This case
can be improved in the future once we see such platforms in mainline.

After this patch, a simple test of booting to a small buildroot rootfs
on qemu shows:

kmalloc-96           5041    5041     96  ...
kmalloc-64           9606    9606     64  ...
kmalloc-32           5128    5128     32  ...
kmalloc-16           7682    7682     16  ...
kmalloc-8           10246   10246      8  ...

So we save about 1268KB memory. The saving will be much larger in normal
OS env on real HW platforms.

patch1 allows kmalloc() caches aligned to the smallest value.
patch2 enables DMA_BOUNCE_UNALIGNED_KMALLOC.

After this series:

As for coherent platforms, kmalloc-{8,16,32,96} caches come back on
coherent both RV32 and RV64 platforms, I.E !ZICBOM and !THEAD_CMO.

As for noncoherent RV32 platforms, nothing changed.

As for noncoherent RV64 platforms, I.E either ZICBOM or THEAD_CMO, the
above kmalloc caches also come back if > 4GB memory or users pass
"swiotlb=mmnn,force" to force swiotlb creation if <= 4GB memory. How
much mmnn should be depends on the specific platform, it needs to be
tried and tested all possible usage case on the specific hardware. For
example, I can use the minimal I/O TLB slabs on Sipeed M1S Dock.

riscv: support PREEMPT_DYNAMIC with static keys 
Currently, each architecture can support PREEMPT_DYNAMIC through
either static calls or static keys. To support PREEMPT_DYNAMIC on
riscv, we face three choices:

1. only add static calls support to riscv
As Mark pointed out in commit 99cf983cc8 ("sched/preempt: Add
PREEMPT_DYNAMIC using static keys"), static keys "...should have
slightly lower overhead than non-inline static calls, as this
effectively inlines each trampoline into the start of its callee. This
may avoid redundant work, and may integrate better with CFI schemes."
So even we add static calls(without inline static calls) to riscv,
static keys is still a better choice.

2. add static calls and inline static calls to riscv
Per my understanding, inline static calls requires objtool support
which is not easy.

3. use static keys

While riscv doesn't have static calls support, it supports static keys
perfectly. So this patch selects HAVE_PREEMPT_DYNAMIC_KEY to enable
support for PREEMPT_DYNAMIC on riscv, so that the preemption model can
be chosen at boot time. It also patches asm-generic/preempt.h, mainly
to add __preempt_schedule() and __preempt_schedule_notrace() macros
for PREEMPT_DYNAMIC case. Other architectures which use generic
preempt.h can also benefit from this patch by simply selecting
HAVE_PREEMPT_DYNAMIC_KEY to enable PREEMPT_DYNAMIC if they supports
static keys.

Merge patch series "riscv: support ELF format binaries in nommu mode" 
Greg Ungerer <gerg@kernel.org> says:

The following changes add the ability to run ELF format binaries when
running RISC-V in nommu mode. That support is actually part of the
ELF-FDPIC loader, so these changes are all about making that work on
RISC-V.

The first issue to deal with is making the ELF-FDPIC loader capable of
handling 64-bit ELF files. As coded right now it only supports 32-bit
ELF files.

Secondly some changes are required to enable and compile the ELF-FDPIC
loader on RISC-V and to pass the ELF-FDPIC mapping addresses through to
user space when execing the new program.

These changes have not been used to run actual ELF-FDPIC binaries.
It is used to load and run normal ELF - compiled -pie format. Though the
underlying changes are expected to work with full ELF-FDPIC binaries if
or when that is supported on RISC-V in gcc.

To avoid needing changes to the C-library (tested with uClibc-ng
currently) there is a simple runtime dynamic loader (interpreter)
available to do the final relocations, https://github.com/gregungerer/uldso.
The nice thing about doing it this way is that the same program
binary can also be loaded with the usual ELF loader in MMU linux.

The motivation here is to provide an easy to use alternative to the
flat format binaries normally used for RISC-V nommu based systems.

Merge patch series "riscv: KCFI support" 
Sami Tolvanen <samitolvanen@google.com> says:

This series adds KCFI support for RISC-V. KCFI is a fine-grained
forward-edge control-flow integrity scheme supported in Clang >=16,
which ensures indirect calls in instrumented code can only branch to
functions whose type matches the function pointer type, thus making
code reuse attacks more difficult.

Patch 1 implements a pt_regs based syscall wrapper to address
function pointer type mismatches in syscall handling. Patches 2 and 3
annotate indirectly called assembly functions with CFI types. Patch 4
implements error handling for indirect call checks. Patch 5 disables
CFI for arch/riscv/purgatory. Patch 6 finally allows CONFIG_CFI_CLANG
to be enabled for RISC-V.

Note that Clang 16 has a generic architecture-agnostic KCFI
implementation, which does work with the kernel, but doesn't produce
a stable code sequence for indirect call checks, which means
potential failures just trap and won't result in informative error
messages. Clang 17 includes a RISC-V specific back-end implementation
for KCFI, which emits a predictable code sequence for the checks and a
.kcfi_traps section with locations of the traps, which patch 5 uses to
produce more useful errors.

The type mismatch fixes and annotations in the first three patches
also become necessary in future if the kernel decides to support
fine-grained CFI implemented using the hardware landing pad
feature proposed in the in-progress Zicfisslp extension. Once the
specification is ratified and hardware support emerges, implementing
runtime patching support that replaces KCFI instrumentation with
Zicfisslp landing pads might also be feasible (similarly to KCFI to
FineIBT patching on x86_64), allowing distributions to ship a unified
kernel binary for all devices.

Merge patch series "support allocating crashkernel above 4G explicitly on riscv" 
Chen Jiahao <chenjiahao16@huawei.com> says:

On riscv, the current crash kernel allocation logic is trying to
allocate within 32bit addressible memory region by default, if
failed, try to allocate without 4G restriction.

In need of saving DMA zone memory while allocating a relatively large
crash kernel region, allocating the reserved memory top down in
high memory, without overlapping the DMA zone, is a mature solution.
Hence this patchset introduces the parameter option crashkernel=X,[high,low].

One can reserve the crash kernel from high memory above DMA zone range
by explicitly passing "crashkernel=X,high"; or reserve a memory range
below 4G with "crashkernel=X,low". Besides, there are few rules need
to take notice:
1. "crashkernel=X,[high,low]" will be ignored if "crashkernel=size"
   is specified.
2. "crashkernel=X,low" is valid only when "crashkernel=X,high" is passed
   and there is enough memory to be allocated under 4G.
3. When allocating crashkernel above 4G and no "crashkernel=X,low" is
   specified, a 128M low memory will be allocated automatically for
   swiotlb bounce buffer.
See Documentation/admin-guide/kernel-parameters.txt for more information.

To verify loading the crashkernel, adapted kexec-tools is attached below:
https://github.com/chenjh005/kexec-tools/tree/build-test-riscv-v2

Following test cases have been performed as expected:
1) crashkernel=256M                          //low=256M
2) crashkernel=1G                            //low=1G
3) crashkernel=4G                            //high=4G, low=128M(default)
4) crashkernel=4G crashkernel=256M,high      //high=4G, low=128M(default), high is ignored
5) crashkernel=4G crashkernel=256M,low       //high=4G, low=128M(default), low is ignored
6) crashkernel=4G,high                       //high=4G, low=128M(default)
7) crashkernel=256M,low                      //low=0M, invalid
8) crashkernel=4G,high crashkernel=256M,low  //high=4G, low=256M
9) crashkernel=4G,high crashkernel=4G,low    //high=0M, low=0M, invalid
10) crashkernel=512M@0xd0000000              //low=512M

4debf77169 iommufd for 6.6 
This includes a shared branch with VFIO:
 
  - Enhance VFIO_DEVICE_GET_PCI_HOT_RESET_INFO so it can work with iommufd
    FDs, not just group FDs. This removes the last place in the uAPI that
    required the group fd.
 
  - Give VFIO a new device node /dev/vfio/devices/vfioX (the so called cdev
    node) which is very similar to the FD from VFIO_GROUP_GET_DEVICE_FD.
    The cdev is associated with the struct device that the VFIO driver is
    bound to and shows up in sysfs in the normal way.
 
  - Add a cdev IOCTL VFIO_DEVICE_BIND_IOMMUFD which allows a newly opened
    /dev/vfio/devices/vfioX to be associated with an IOMMUFD, this replaces
    the VFIO_GROUP_SET_CONTAINER flow.
 
  - Add cdev IOCTLs VFIO_DEVICE_[AT|DE]TACH_IOMMUFD_PT to allow the IOMMU
    translation the vfio_device is associated with to be changed. This is a
    significant new feature for VFIO as previously each vfio_device was
    fixed to a single translation.
 
    The translation is under the control of iommufd, so it can be any of
    the different translation modes that iommufd is learning to create.
 
 At this point VFIO has compilation options to remove the legacy interfaces
 and in modern mode it behaves like a normal driver subsystem. The
 /dev/vfio/iommu and /dev/vfio/groupX nodes are not present and each
 vfio_device only has a /dev/vfio/devices/vfioX cdev node that represents
 the device.
 
 On top of this is built some of the new iommufd functionality:
 
  - IOMMU_HWPT_ALLOC allows userspace to directly create the low level
    IO Page table objects and affiliate them with IOAS objects that hold
    the translation mapping. This is the basic functionality for the
    normal IOMMU_DOMAIN_PAGING domains.
 
  - VFIO_DEVICE_ATTACH_IOMMUFD_PT can be used to replace the current
    translation. This is wired up to through all the layers down to the
    driver so the driver has the ability to implement a hitless
    replacement. This is necessary to fully support guest behaviors when
    emulating HW (eg guest atomic change of translation)
 
  - IOMMU_GET_HW_INFO returns information about the IOMMU driver HW that
    owns a VFIO device. This includes support for the Intel iommu, and
    patches have been posted for all the other server IOMMU.
 
 Along the way are a number of internal items:
 
  - New iommufd kapis iommufd_ctx_has_group(), iommufd_device_to_ictx(),
    iommufd_device_to_id(), iommufd_access_detach(), iommufd_ctx_from_fd(),
    iommufd_device_replace()
 
  - iommufd now internally tracks iommu_groups as it needs some per-group
    data
 
  - Reorganize how the internal hwpt allocation flows to have more robust
    locking
 
  - Improve the access interfaces to support detach and replace of an IOAS
    from an access
 
  - New selftests and a rework of how the selftests creates a mock iommu
    driver to be more like a real iommu driver

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:
   - Add locking to read/modify/write PCIe Capability Register accessors
     for Link Control and Root Control
   - Use pci_dev_id() when possible instead of manually composing ID
     from dev->bus->number and dev->devfn

  Resource management:
   - Move prototypes for __weak sysfs resource files to linux/pci.h to
     fix 'no previous prototype' warnings
   - Make more I/O port accesses depend on HAS_IOPORT
   - Use devm_platform_get_and_ioremap_resource() instead of open-coding
     platform_get_resource() followed by devm_ioremap_resource()

  Power management:
   - Ensure devices are powered up while accessing VPD
   - If device is powered-up, keep it that way while polling for PME
   - Only read PCI_PM_CTRL register when available, to avoid reading the
     wrong register and corrupting dev->current_state

  Virtualization:
   - Avoid Secondary Bus Reset on NVIDIA T4 GPUs

  Error handling:
   - Remove unused pci_disable_pcie_error_reporting()
   - Unexport pci_enable_pcie_error_reporting(), used only by aer.c
   - Unexport pcie_port_bus_type, used only by PCI core

  VGA:
   - Simplify and clean up typos in VGA arbiter

  Apple PCIe controller driver:
   - Initialize pcie->nvecs (number of available MSIs) before use

  Broadcom iProc PCIe controller driver:
   - Use of_property_read_bool() instead of low-level accessors for
     boolean properties

  Broadcom STB PCIe controller driver:
   - Assert PERST# when probing BCM2711 because some bootloaders don't
     do it

  Freescale i.MX6 PCIe controller driver:
   - Add .host_deinit() callback so we can clean up things like
     regulators on probe failure or driver unload

  Freescale Layerscape PCIe controller driver:
   - Add support for link-down notification so the endpoint driver can
     process LINK_DOWN events
   - Add suspend/resume support, including manual
     PME_Turn_off/PME_TO_Ack handshake
   - Save Link Capabilities during probe so they can be restored when
     handling a link-up event, since the controller loses the Link Width
     and Link Speed values during reset

  Intel VMD host bridge driver:
   - Fix disable of bridge windows during domain reset; previously we
     cleared the base/limit registers, which actually left the windows
     enabled

  Marvell MVEBU PCIe controller driver:
   - Remove unused busn member

  Microchip PolarFlare PCIe controller driver:
   - Fix interrupt bit definitions so the SEC and DED interrupt handlers
     work correctly
   - Make driver buildable as a module
   - Read FPGA MSI configuration parameters from hardware instead of
     hard-coding them

  Microsoft Hyper-V host bridge driver:
   - To avoid a NULL pointer dereference, skip MSI restore after
     hibernate if MSI/MSI-X hasn't been enabled

  NVIDIA Tegra194 PCIe controller driver:
   - Revert 'PCI: tegra194: Enable support for 256 Byte payload' because
     Linux doesn't know how to reduce MPS from to 256 to 128 bytes for
     endpoints below a switch (because other devices below the switch
     might already be operating), which leads to 'Malformed TLP' errors

  Qualcomm PCIe controller driver:
   - Add DT and driver support for interconnect bandwidth voting for
     'pcie-mem' and 'cpu-pcie' interconnects
   - Fix broken SDX65 'compatible' DT property
   - Configure controller so MHI bus master clock will be switched off
     while in ASPM L1.x states
   - Use alignment restriction from EPF core in EPF MHI driver
   - Add Endpoint eDMA support
   - Add MHI eDMA support
   - Add Snapdragon SM8450 support to the EPF MHI driversupport
   - Add MHI eDMA support
   - Add Snapdragon SM8450 support to the EPF MHI driversupport
   - Add MHI eDMA support
   - Add Snapdragon SM8450 support to the EPF MHI driversupport
   - Add MHI eDMA support
   - Add Snapdragon SM8450 support to the EPF MHI driver
   - Use iATU for EPF MHI transfers smaller than 4K to avoid eDMA setup
     latency
   - Add sa8775p DT binding and driver support

  Rockchip PCIe controller driver:
   - Use 64-bit mask on MSI 64-bit PCI address to avoid zeroing out the
     upper 32 bits

  SiFive FU740 PCIe controller driver:
   - Set the supported number of MSI vectors so we can use all available
     MSI interrupts

  Synopsys DesignWare PCIe controller driver:
   - Add generic dwc suspend/resume APIs (dw_pcie_suspend_noirq() and
     dw_pcie_resume_noirq()) to be called by controller driver
     suspend/resume ops, and a controller callback to send PME_Turn_Off

  MicroSemi Switchtec management driver:
   - Add support for PCIe Gen5 devices

  Miscellaneous:
   - Reorder and compress to reduce size of struct pci_dev
   - Fix race in DOE destroy_work_on_stack()
   - Add stubs to avoid casts between incompatible function types
   - Explicitly include correct DT includes to untangle headers"

changes to the clk framework this time around. That's probably because everyone
 was on vacation (yours truly included). We did lose a couple clk drivers this
 time around because nobody was using those devices. That skews the diffstat a
 bit, but either way, nothing looks out of the ordinary here. The usual suspects
 are chugging along adding support for more SoCs and fixing bugs.
 
 If I had to choose, I'd say the theme for the past few months has been
 "polish". There's quite a few patches that migrate to
 devm_platform_ioremap_resource() in here. And there's more than a handful of
 patches that move the NR_CLKS define from the DT binding header to the driver.
 There's even patches that migrate drivers to use clk_parent_data and clk_hw to
 describe clk tree topology. It seems that the spring (summer?) cleaning bug got
 some folks, or the semiconductor shortage finally hit the software side.
 
 New Drivers:
  - StarFive JH7110 SoC clock drivers
  - Qualcomm IPQ5018 Global Clock Controller driver
  - Versa3 clk generator to support 48KHz playback/record with audio codec on
    RZ/G2L SMARC EVK

8f447694c2 Devicetree updates for v6.6: 
DT core:
 - Add support for generating DT nodes for PCI devices. This is the
   groundwork for applying overlays to PCI devices containing
   non-discoverable downstream devices.
 
 - DT unittest additions to check reverted changesets, to test for
   refcount issues, and to test unresolved symbols. Also, various
   clean-ups of the unittest along the way.
 
 - Refactor node and property manipulation functions to better share code
   with old API and changeset API
 
 - Refactor changeset print functions to a common implementation
 
 - Move some platform_device specific functions into of_platform.c
 
 Bindings:
 - Treewide fixing of typos
 
 - Treewide clean-up of SPDX tags to use 'OR' consistently
 
 - Last chunk of dropping unnecessary quotes. With that, the check
   for unnecessary quotes is enabled in yamllint.
 
 - Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
   bindings to DT schema format
 
 - Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450 Inline
   Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt controller,
   Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings
 
 - Fixes for Rockchip DWC PCI binding
 
 - Ensure all properties are evaluated on USB connector schema
 
 - Fix dt-check-compatible script to find of_device_id instances with
   compiler annotations

0e72db7767 ARM: devicetree updates for 6.6 
These are the devicetree updates for Arm and RISC-V based SoCs,
 mainly from Qualcomm, NXP/Freescale, Aspeed, TI, Rockchips,
 Samsung, ST and Starfive.
 
 Only a few new SoC got added:
 
  - TI AM62P5, a variant of the existing Sitara AM62x family
 
  - Intel Agilex5, an FPGFA platform that includes an
    Cortex-A76/A55 SoC.
 
  - Qualcomm ipq5018 is used in wireless access points
 
  - Qualcomm SM4450 (Snapdragon 4 Gen 2) is a new low-end mobile
    phone platform.
 
 In total, 29 machines get added, which is low because of the summer
 break. These cover SoCs from Aspeed, Broadcom, NXP, Samsung, ST,
 Allwinner, Amlogic, Intel, Qualcomm, Rockchip, TI and T-Head.  Most of
 these are development and reference boards.
 
 Despite not adding a lot of new machines, there are over 700 patches in
 total, most of which are cleanups and minor fixes.

1544df9ab4 ARM: SoC drivers for 6.6 
The main change this time is the introduction of the drivers/genpd
 subsystem that gets split out from drivers/soc to keep common
 functionality together. Ulf Hansson is taking over maintainership for
 these and is sending a separate pull request with the same commits,
 but they are in the soc drivers tree to avoid conflicts against other
 soc driver patches.
 
 The SCMI driver subsystem gets an update to version 3.2 of the
 specification. There are also updates to memory, reset and other firmware
 drivers.
 
 On the soc driver side, the updates are mostly cleanups across a number
 of Arm platforms. On driver for loongarch adds power management for DT
 based systems, another driver is for HiSilicon's Arm server chips with
 their HCCS system health interface.
 
 The remaining updates for the most part add support for additional
 hardware in existing drivers or contain minor cleanups. Most of these
 are for the Qualcomm Snapdragon platform.

Merge tag 'genpd-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm

Pull ARM SoC generic power domain driver updates from Ulf Hansson:
 "This adds a new subsystem for generic power domain providers in
  drivers/genpd and starts moving some of the corresponding code in
  there.

  We have currently ~60 users of the genpd provider interface, which are
  sprinkled across various subsystems. To release some burden from the
  soc maintainers (Arnd Bergmann, etc) in particular, but also to gain a
  better overall view of what goes on in the area, I will help out with
  maintenance"

[ I find the "genpd" name singularly uninformative, so we'll probably
  end up moving this driver subsystem somewhere else, but that's still
  being discussed  - Linus ]

4fb0dacb78 sound updates for 6.6-rc1 
We've received a fairly wide range of changes at this time, including
 for ALSA and ASoC core, but all of them are rather small changes.
 
 Here are some highlights:
 
 ALSA / ASoC Core:
 - Fixes of inconsistent locking around control API helpers
 - A few new control API functions and cleanups
 - Workarounds for potential UAFs by delayed kobj releases
 - Unified PCM copy ops with iov_iter
 - Continued efforts for ASoC API cleanups
 
 ASoC:
 - An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
   some IIO changes
 - Create a library function for intlog10() and use it in the NAU8825
   driver
 - Convert drivers to use the more modern maple tree register cache
 - Lots of work on the SOF framework, AMD and Intel drivers, including a
   lot of cleanup and new device support
 - Standardization of the presentation of jacks from drivers
 - Provision of some generic sound card DT properties
 - Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,
   AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel
   platforms including AVS machines with ES8336 and RT5663, Mediatek
   MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110
 
 Others:
 - New test coverage including ASoC and topology tests in KUnit;
   this also involves enabling UML builds of ALSA since that's the
   default KUnit test environment which pulls in the addition of some
   stubs to the driver
 - More enhancement of pcmtest driver
 - A few fixes / enhancements of MIDI 2.0 UMP core
 - Using PCI definitions in allover HD-audio code
 - Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs
 - CS35L41 HD-audio sub-codec improvements
 - Continued emu10k1 improvements

53ea7f624f New code for 6.6: 
* Chandan Babu will be taking over as the XFS release manager.  He has
    reviewed all the patches that are in this branch, though I'm signing
    the branch one last time since I'm still technically maintainer. :P
  * Create a maintainer entry profile for XFS in which we lay out the
    various roles that I have played for many years.  Aside from release
    manager, the remaining roles are as yet unfilled.
  * Start merging online repair -- we now have in-memory pageable memory
    for staging btrees, a bunch of pending fixes, and we've started the
    process of refactoring the scrub support code to support more of
    repair.  In particular, reaping of old blocks from damaged structures.
  * Scrub the realtime summary file.
  * Fix a bug where scrub's quota iteration only ever returned the root
    dquot.  Oooops.
  * Fix some typos.

c4a123d2e8 pNFS: Fix assignment of xprtdata.cred 
The comma at the end of the line was leftover from an earlier refactor
of the _nfs4_pnfs_v3_ds_connect() function. This is technically valid C,
so the compilers didn't catch it, but if I'm understanding how it works
correctly it assigns the return value of rpc_clnt_add_xprtr() to
xprtdata.cred.

Merge tag 'x86_apic_for_6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 apic updates from Dave Hansen:
 "This includes a very thorough rework of the 'struct apic' handlers.
  Quite a variety of them popped up over the years, especially in the
  32-bit days when odd apics were much more in vogue.

  The end result speaks for itself, which is a removal of a ton of code
  and static calls to replace indirect calls.

  If there's any breakage here, it's likely to be around the 32-bit
  museum pieces that get light to no testing these days.

  Summary:

   - Rework apic callbacks, getting rid of unnecessary ones and
     coalescing lots of silly duplicates.

   - Use static_calls() instead of indirect calls for apic->foo()

   - Tons of cleanups an crap removal along the way"

87fa732dc5 X86 core updates: 
- Prevent kprobes on compiler generated CFI checking code.
 
     The compiler generates a instruction sequence for indirect call
     checks. If this sequence is modified with a kprobe, then the check
     fails. So the instructions must be protected against probing.
 
   - A few minor cleanups for the SMP code
