asm-generic: Improve csum_fold
This csum_fold implementation introduced into arch/arc by Vineet Gupta is better than the default implementation on at least arc, x86, and riscv. Using GCC trunk and compiling non-inlined version, this implementation has 41.6667%, 25% fewer instructions on riscv64, x86-64 respectively with -O3 optimization. Most implmentations override this default in asm, but this should be more performant than all of those other implementations except for arm which has barrel shifting and sparc32 which has a carry flag.

RISC-V: selftests: cbo: Ensure asm operands match constraints
The 'i' constraint expects a constant operand, which fn and its
constant derivative MK_CBO(fn) are, but passing fn through a function
as a parameter and using a local variable for MK_CBO(fn) allow the
compiler to lose sight of that when no optimization is done. Use
a macro instead of a function and skip the local variable to ensure
the compiler uses constants, matching the asm constraints.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Reserve ECAM so we don't assign it to PCI BARs; this works around
bugs where BIOS included ECAM in a PNP0A03 host bridge window,
didn't reserve it via a PNP0C02 motherboard device, and didn't
allocate space for SR-IOV VF BARs (Bjorn Helgaas)
- Add MMCONFIG/ECAM debug logging (Bjorn Helgaas)
- Rename 'MMCONFIG' to 'ECAM' to match spec usage (Bjorn Helgaas)
- Log device type (Root Port, Switch Port, etc) during enumeration
(Bjorn Helgaas)
- Log bridges before downstream devices so the dmesg order is more
logical (Bjorn Helgaas)
- Log resource names (BAR 0, VF BAR 0, bridge window, etc)
consistently instead of a mix of names and "reg 0x10" (Puranjay
Mohan, Bjorn Helgaas)
- Fix 64GT/s effective data rate calculation to use 1b/1b encoding
rather than the 8b/10b or 128b/130b used by lower rates (Ilpo
Järvinen)
- Use PCI_HEADER_TYPE_* instead of literals in x86, powerpc, SCSI
lpfc (Ilpo Järvinen)
- Clean up open-coded PCIBIOS return code mangling (Ilpo Järvinen)
Resource management:
- Restructure pci_dev_for_each_resource() to avoid computing the
address of an out-of-bounds array element (the bounds check was
performed later so the element was never actually *read*, but it's
nicer to avoid even computing an out-of-bounds address) (Andy
Shevchenko)
Driver binding:
- Convert pci-host-common.c platform .remove() callback to
.remove_new() returning 'void' since it's not useful to return
error codes here (Uwe Kleine-König)
- Convert exynos, keystone, kirin from .remove() to .remove_new(),
which returns void instead of int (Uwe Kleine-König)
- Drop unused struct pci_driver.node member (Mathias Krause)
Virtualization:
- Add ACS quirk for more Zhaoxin Root Ports (LeoLiuoc)
Error handling:
- Log AER errors as "Correctable" (not "Corrected") or
"Uncorrectable" to match spec terminology (Bjorn Helgaas)
- Decode Requester ID when no error info found instead of printing
the raw hex value (Bjorn Helgaas)
Endpoint framework:
- Use a unique test pattern for each BAR in the pci_endpoint_test to
make it easier to debug address translation issues (Niklas Cassel)
Broadcom STB PCIe controller driver:
- Add DT property "brcm,clkreq-mode" and driver support for different
CLKREQ# modes to make ASPM L1.x states possible (Jim Quinlan)
Freescale Layerscape PCIe controller driver:
- Add suspend/resume support for Layerscape LS1043a and LS1021a,
including software-managed PME_Turn_Off and transitions between L0,
L2/L3_Ready Link states (Frank Li)
MediaTek PCIe controller driver:
- Clear MSI interrupt status before handler to avoid missing MSIs
that occur after the handler (qizhong cheng)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 translation window setup to handle MMIO space
that is not a power of two in size (Jianjun Wang)
Qualcomm PCIe controller driver:
- Increase qcom iommu-map maxItems to accommodate SDX55 (five
entries) and SDM845 (sixteen entries) (Krzysztof Kozlowski)
- Describe qcom,pcie-sc8180x clocks and resets accurately (Krzysztof
Kozlowski)
- Describe qcom,pcie-sm8150 clocks and resets accurately (Krzysztof
Kozlowski)
- Correct the qcom "reset-name" property, previously incorrectly
called "reset-names" (Krzysztof Kozlowski)
- Document qcom,pcie-sm8650, based on qcom,pcie-sm8550 (Neil
Armstrong)
Renesas R-Car PCIe controller driver:
- Replace of_device.h with explicit of.h include to untangle header
usage (Rob Herring)
- Add DT and driver support for optional miniPCIe 1.5v and 3.3v
regulators on KingFisher (Wolfram Sang)
SiFive FU740 PCIe controller driver:
- Convert fu740 CONFIG_PCIE_FU740 dependency from SOC_SIFIVE to
ARCH_SIFIVE (Conor Dooley)
Synopsys DesignWare PCIe controller driver:
- Align iATU mapping for endpoint MSI-X (Niklas Cassel)
- Drop "host_" prefix from struct dw_pcie_host_ops members (Yoshihiro
Shimoda)
- Drop "ep_" prefix from struct dw_pcie_ep_ops members (Yoshihiro
Shimoda)
- Rename struct dw_pcie_ep_ops.func_conf_select() to
.get_dbi_offset() to be more descriptive (Yoshihiro Shimoda)
- Add Endpoint DBI accessors to encapsulate offset lookups (Yoshihiro
Shimoda)
TI J721E PCIe driver:
- Add j721e DT and driver support for 'num-lanes' for devices that
support x1, x2, or x4 Links (Matt Ranostay)
- Add j721e DT compatible strings and driver support for j784s4 (Matt
Ranostay)
- Make TI J721E Kconfig depend on ARCH_K3 since the hardware is
specific to those TI SoC parts (Peter Robinson)
TI Keystone PCIe controller driver:
- Hold power management references to all PHYs while enabling them to
avoid a race when one provides clocks to others (Siddharth
Vadapalli)
Xilinx XDMA PCIe controller driver:
- Remove redundant dev_err(), since platform_get_irq() and
platform_get_irq_byname() already log errors (Yang Li)
- Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq()
(Krzysztof Wilczyński)
- Fix xilinx_pl_dma_pcie_init_irq_domain() error return when
irq_domain_add_linear() fails (Harshit Mogalapalli)
MicroSemi Switchtec management driver:
- Do dma_mrpc cleanup during switchtec_pci_remove() to match its devm
ioremapping in switchtec_pci_probe(). Previously the cleanup was
done in stdev_release(), which used stale pointers if stdev->cdev
happened to be open when the PCI device was removed (Daniel
Stodden)
Miscellaneous:
- Convert interrupt terminology from "legacy" to "INTx" to be more
specific and match spec terminology (Damien Le Moal)
- In dw-xdata-pcie, pci_endpoint_test, and vmd, replace usage of
deprecated ida_simple_*() API with ida_alloc() and ida_free()
(Christophe JAILLET)"

rtc: nuvoton: Compatible with NCT3015Y-R and NCT3018Y-R
The NCT3015Y-R and NCT3018Y-R use the same datasheet
but have different topologies as follows.
- Topology (Only 1st i2c can set TWO bit and HF bit)
In NCT3015Y-R,
rtc 1st i2c is connected to a host CPU
rtc 2nd i2c is connected to a BMC
In NCT3018Y-R,
rtc 1st i2c is connected to a BMC
rtc 2nd i2c is connected to a host CPU
In order to be compatible with NCT3015Y-R and NCT3018Y-R,
- In probe,
If part number is NCT3018Y-R, only set HF bit to 24-Hour format.
Else, do nothing
- In set_time,
If part number is NCT3018Y-R && TWO bit is 0,
change TWO bit to 1, and restore TWO bit after updating time.

This is the main pin control pull request for the v6.8 kernel series.
Core changes:
- A new PINCTRL_GROUP_DESC() infrastructure macro is added and
used in different drivers, generic group description struct
group_desc is now used all over the place.
New drivers:
- New driver for the Texas Instruments TPS6494 Power Management IC.
- New driver for the Lantic PEF2256 framer pin multiplexer.
This IC has some pins that can be reconfigured in different
ways. The actual driver comes on an immutable branch with the
net WAN parts, the IC is some latest-and-greatest serial line
funnel for e.g. wireless access points.
- New subdriver for the Samsung Exynos Auto V920 pin controller,
used for automotive applications.
- New subdriver for the Samsung "GS101" SoC pin controller, this
is the Google "Tensor" SoC used in the Google Pixel 6.
- New subdriver for the Intel Meteor Point SoC pin controller.
- New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS pin
controllers.
- New subdriver for the Qualcomm X1E80100 top level (TLMM) pin
controller.
- New subdriver for the Qualcomm SM4450 top level (TLMM) pin
controller.
- The "single" pin controller now supports the Texas Instruments
J7200 SoC.
Improvements:
- Intel has created a new (Intel-)generic pin controller driver that
is now used by all contemporary Intel platforms.
- Intel is now also making use of some cleanup helpers.
- Enble 910 Ohm bias in the Intel Tangier driver.
- The Samsung driver now suppors irq_set_affinity() in it's IRQ chip
giving support for non wake up external gpio interrupts.

your tree through the net pull request but here it is mentioned again.
The most interesting is perhaps the Samsung Exynos subdrivers for the
Tensor SoC used in Google Pixel 6 and the ExynosAuto subdriver for
automotive. Along with the earlier merged Tesla FSD subdriver it shows
some of the versatile uses of the Samsung Exynos silicon. It is also
used in the latest version of Axis Communications ARTPEC chips so it
is a very widely deployed SoC family.
We also have the Intel Meteor Lake SoC which I think is for laptops.
It's a pretty interesting chip with Xe graphics and integrated PCH.
Core changes:
- A new PINCTRL_GROUP_DESC() infrastructure macro is added and used
in different drivers, generic group description struct group_desc
is now used all over the place.
New drivers:
- New driver for the Texas Instruments TPS6494 Power Management IC.
- New driver for the Lantic PEF2256 framer pin multiplexer. This IC
has some pins that can be reconfigured in different ways. The
actual driver comes on an immutable branch with the net WAN parts,
the IC is some latest-and-greatest serial line funnel for e.g.
wireless access points.
- New subdriver for the Samsung Exynos Auto V920 pin controller, used
for automotive applications.
- New subdriver for the Samsung "GS101" SoC pin controller, this is
the Google "Tensor" SoC used in the Google Pixel 6.
- New subdriver for the Intel Meteor Point SoC pin controller.
- New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS
pin controllers.
- New subdriver for the Qualcomm X1E80100 top level (TLMM) pin
controller.
- New subdriver for the Qualcomm SM4450 top level (TLMM) pin
controller.
- The "single" pin controller now supports the Texas Instruments
J7200 SoC.
Improvements:
- Intel has created a new (Intel-)generic pin controller driver that
is now used by all contemporary Intel platforms.
- Intel is now also making use of some cleanup helpers.
- Enble 910 Ohm bias in the Intel Tangier driver.
- The Samsung driver now suppors irq_set_affinity() in it's IRQ chip
giving support for non wake up external gpio interrupts"

Generic:
- Use memdup_array_user() to harden against overflow.
- Unconditionally advertise KVM_CAP_DEVICE_CTRL for all architectures.
- Clean up Kconfigs that all KVM architectures were selecting
- New functionality around "guest_memfd", a new userspace API that
creates an anonymous file and returns a file descriptor that refers
to it. guest_memfd files are bound to their owning virtual machine,
cannot be mapped, read, or written by userspace, and cannot be resized.
guest_memfd files do however support PUNCH_HOLE, which can be used to
switch a memory area between guest_memfd and regular anonymous memory.
- New ioctl KVM_SET_MEMORY_ATTRIBUTES allowing userspace to specify
per-page attributes for a given page of guest memory; right now the
only attribute is whether the guest expects to access memory via
guest_memfd or not, which in Confidential SVMs backed by SEV-SNP,
TDX or ARM64 pKVM is checked by firmware or hypervisor that guarantees
confidentiality (AMD PSP, Intel TDX module, or EL2 in the case of pKVM).
x86:
- Support for "software-protected VMs" that can use the new guest_memfd
and page attributes infrastructure. This is mostly useful for testing,
since there is no pKVM-like infrastructure to provide a meaningfully
reduced TCB.
- Fix a relatively benign off-by-one error when splitting huge pages during
CLEAR_DIRTY_LOG.
- Fix a bug where KVM could incorrectly test-and-clear dirty bits in non-leaf
TDP MMU SPTEs if a racing thread replaces a huge SPTE with a non-huge SPTE.
- Use more generic lockdep assertions in paths that don't actually care
about whether the caller is a reader or a writer.
- let Xen guests opt out of having PV clock reported as "based on a stable TSC",
because some of them don't expect the "TSC stable" bit (added to the pvclock
ABI by KVM, but never set by Xen) to be set.
- Revert a bogus, made-up nested SVM consistency check for TLB_CONTROL.
- Advertise flush-by-ASID support for nSVM unconditionally, as KVM always
flushes on nested transitions, i.e. always satisfies flush requests. This
allows running bleeding edge versions of VMware Workstation on top of KVM.
- Sanity check that the CPU supports flush-by-ASID when enabling SEV support.
- On AMD machines with vNMI, always rely on hardware instead of intercepting
IRET in some cases to detect unmasking of NMIs
- Support for virtualizing Linear Address Masking (LAM)
- Fix a variety of vPMU bugs where KVM fail to stop/reset counters and other state
prior to refreshing the vPMU model.
- Fix a double-overflow PMU bug by tracking emulated counter events using a
dedicated field instead of snapshotting the "previous" counter. If the
hardware PMC count triggers overflow that is recognized in the same VM-Exit
that KVM manually bumps an event count, KVM would pend PMIs for both the
hardware-triggered overflow and for KVM-triggered overflow.
- Turn off KVM_WERROR by default for all configs so that it's not
inadvertantly enabled by non-KVM developers, which can be problematic for
subsystems that require no regressions for W=1 builds.
- Advertise all of the host-supported CPUID bits that enumerate IA32_SPEC_CTRL
"features".
- Don't force a masterclock update when a vCPU synchronizes to the current TSC
generation, as updating the masterclock can cause kvmclock's time to "jump"
unexpectedly, e.g. when userspace hotplugs a pre-created vCPU.
- Use RIP-relative address to read kvm_rebooting in the VM-Enter fault paths,
partly as a super minor optimization, but mostly to make KVM play nice with
position independent executable builds.
- Guard KVM-on-HyperV's range-based TLB flush hooks with an #ifdef on
CONFIG_HYPERV as a minor optimization, and to self-document the code.
- Add CONFIG_KVM_HYPERV to allow disabling KVM support for HyperV "emulation"
at build time.
ARM64:
- LPA2 support, adding 52bit IPA/PA capability for 4kB and 16kB
base granule sizes. Branch shared with the arm64 tree.
- Large Fine-Grained Trap rework, bringing some sanity to the
feature, although there is more to come. This comes with
a prefix branch shared with the arm64 tree.
- Some additional Nested Virtualization groundwork, mostly
introducing the NV2 VNCR support and retargetting the NV
support to that version of the architecture.
- A small set of vgic fixes and associated cleanups.
Loongarch:
- Optimization for memslot hugepage checking
- Cleanup and fix some HW/SW timer issues
- Add LSX/LASX (128bit/256bit SIMD) support
RISC-V:
- KVM_GET_REG_LIST improvement for vector registers
- Generate ISA extension reg_list using macros in get-reg-list selftest
- Support for reporting steal time along with selftest
s390:
- Bugfixes
Selftests:
- Fix an annoying goof where the NX hugepage test prints out garbage
instead of the magic token needed to run the test.
- Fix build errors when a header is delete/moved due to a missing flag
in the Makefile.
- Detect if KVM bugged/killed a selftest's VM and print out a helpful
message instead of complaining that a random ioctl() failed.
- Annotate the guest printf/assert helpers with __printf(), and fix the
various bugs that were lurking due to lack of said annotation.
There are two non-KVM patches buried in the middle of guest_memfd support:
fs: Rename anon_inode_getfile_secure() and anon_inode_getfd_secure()
mm: Add AS_UNMOVABLE to mark mapping as completely unmovable
The first is small and mostly suggested-by Christian Brauner; the second
a bit less so but it was written by an mm person (Vlastimil Babka).

- Fix a double-overflow PMU bug by tracking emulated counter events
using a dedicated field instead of snapshotting the "previous"
counter. If the hardware PMC count triggers overflow that is
recognized in the same VM-Exit that KVM manually bumps an event
count, KVM would pend PMIs for both the hardware-triggered overflow
and for KVM-triggered overflow.
- Turn off KVM_WERROR by default for all configs so that it's not
inadvertantly enabled by non-KVM developers, which can be
problematic for subsystems that require no regressions for W=1
builds.
- Advertise all of the host-supported CPUID bits that enumerate
IA32_SPEC_CTRL "features".
- Don't force a masterclock update when a vCPU synchronizes to the
current TSC generation, as updating the masterclock can cause
kvmclock's time to "jump" unexpectedly, e.g. when userspace
hotplugs a pre-created vCPU.
- Use RIP-relative address to read kvm_rebooting in the VM-Enter
fault paths, partly as a super minor optimization, but mostly to
make KVM play nice with position independent executable builds.
- Guard KVM-on-HyperV's range-based TLB flush hooks with an #ifdef on
CONFIG_HYPERV as a minor optimization, and to self-document the
code.
- Add CONFIG_KVM_HYPERV to allow disabling KVM support for HyperV
"emulation" at build time.
ARM64:
- LPA2 support, adding 52bit IPA/PA capability for 4kB and 16kB base
granule sizes. Branch shared with the arm64 tree.
- Large Fine-Grained Trap rework, bringing some sanity to the
feature, although there is more to come. This comes with a prefix
branch shared with the arm64 tree.
- Some additional Nested Virtualization groundwork, mostly
introducing the NV2 VNCR support and retargetting the NV support to
that version of the architecture.
- A small set of vgic fixes and associated cleanups.
Loongarch:
- Optimization for memslot hugepage checking
- Cleanup and fix some HW/SW timer issues
- Add LSX/LASX (128bit/256bit SIMD) support
RISC-V:
- KVM_GET_REG_LIST improvement for vector registers
- Generate ISA extension reg_list using macros in get-reg-list
selftest
- Support for reporting steal time along with selftest
s390:
- Bugfixes
Selftests:
- Fix an annoying goof where the NX hugepage test prints out garbage
instead of the magic token needed to run the test.
- Fix build errors when a header is delete/moved due to a missing
flag in the Makefile.
- Detect if KVM bugged/killed a selftest's VM and print out a helpful
message instead of complaining that a random ioctl() failed.
- Annotate the guest printf/assert helpers with __printf(), and fix
the various bugs that were lurking due to lack of said annotation"

Pull vfs fixes from Christian Brauner:
"This contains two fixes for the current merge window. The listmount
changes that you requested and a fix for a fsnotify performance
regression:
- The proposed listmount changes are currently under my authorship. I
wasn't sure whether you'd wanted to be author as the patch wasn't
signed off. If you do I'm happy if you just apply your own patch.
I've tested the patch with my sh4 cross-build setup. And confirmed
that a) the build failure with sh on current upstream is
reproducible and that b) the proposed patch fixes the build
failure. That should only leave the task of fixing put_user on sh.
- The fsnotify regression was caused by moving one of the hooks out
of the security hook in preparation for other fsnotify work. This
meant that CONFIG_SECURITY would have compiled out the fsnotify
hook before but didn't do so now.
That lead to up to 6% performance regression in some io_uring
workloads that compile all fsnotify and security checks out. Fix
this by making sure that the relevant hooks are covered by the
already existing CONFIG_FANOTIFY_ACCESS_PERMISSIONS where the
relevant hook belongs"

kdb: Fix a potential buffer overflow in kdb_local()
When appending "[defcmd]" to 'kdb_prompt_str', the size of the string
already in the buffer should be taken into account.
An option could be to switch from strncat() to strlcat() which does the
correct test to avoid such an overflow.
However, this actually looks as dead code, because 'defcmd_in_progress'
can't be true here.
See a more detailed explanation at [1].

io_uring: adjust defer tw counting
The UINT_MAX work item counting bias in io_req_local_work_add() in case
of !IOU_F_TWQ_LAZY_WAKE works in a sense that we will not miss a wake up,
however it's still eerie. In particular, if we add a lazy work item
after a non-lazy one, we'll increment it and get nr_tw==0, and
subsequent adds may try to unnecessarily wake up the task, which is
though not so likely to happen in real workloads.
Half the bias, it's still large enough to be larger than any valid
->cq_wait_nr, which is limited by IORING_MAX_CQ_ENTRIES, but further
have a good enough of space before it overflows.

s390/vfio-ap: do not reset queue removed from host config
When a queue is unbound from the vfio_ap device driver, it is reset to
ensure its crypto data is not leaked when it is bound to another device
driver. If the queue is unbound due to the fact that the adapter or domain
was removed from the host's AP configuration, then attempting to reset it
will fail with response code 01 (APID not valid) getting returned from the
reset command. Let's ensure that the queue is assigned to the host's
configuration before resetting it.

s390/vfio-ap: reset queues associated with adapter for queue unbound from driver
When a queue is unbound from the vfio_ap device driver, if that queue is
assigned to a guest's AP configuration, its associated adapter is removed
because queues are defined to a guest via a matrix of adapters and
domains; so, it is not possible to remove a single queue.
If an adapter is removed from the guest's AP configuration, all associated
queues must be reset to prevent leaking crypto data should any of them be
assigned to a different guest or device driver. The one caveat is that if
the queue is being removed because the adapter or domain has been removed
from the host's AP configuration, then an attempt to reset the queue will
fail with response code 01, AP-queue number not valid; so resetting these
queues should be skipped.

s390/vfio-ap: reset queues filtered from the guest's AP config
When filtering the adapters from the configuration profile for a guest to
create or update a guest's AP configuration, if the APID of an adapter and
the APQI of a domain identify a queue device that is not bound to the
vfio_ap device driver, the APID of the adapter will be filtered because an
individual APQN can not be filtered due to the fact the APQNs are assigned
to an AP configuration as a matrix of APIDs and APQIs. Consequently, a
guest will not have access to all of the queues associated with the
filtered adapter. If the queues are subsequently made available again to
the guest, they should re-appear in a reset state; so, let's make sure all
queues associated with an adapter unplugged from the guest are reset.
In order to identify the set of queues that need to be reset, let's allow a
vfio_ap_queue object to be simultaneously stored in both a hashtable and a
list: A hashtable used to store all of the queues assigned
to a matrix mdev; and/or, a list used to store a subset of the queues that
need to be reset. For example, when an adapter is hot unplugged from a
guest, all guest queues associated with that adapter must be reset. Since
that may be a subset of those assigned to the matrix mdev, they can be
stored in a list that can be passed to the vfio_ap_mdev_reset_queues
function.
