Summary of significant series in this pull request:
- The 4 patch series "mm: ksm: prevent KSM from breaking merging of new
VMAs" from Lorenzo Stoakes addresses an issue with KSM's
PR_SET_MEMORY_MERGE mode: newly mapped VMAs were not eligible for
merging with existing adjacent VMAs.

practical access monitoring" from SeongJae Park adds a new kernel module
which simplifies the setup and usage of DAMON in production
environments.

does that. A 37% reduction in execution time was measured in a
memset+mremap+munmap microbenchmark.
- The 5 patch series "Remove zero_user()" from Matthew Wilcox expunges
zero_user() in favor of the more modern memzero_page().
- The 3 patch series "mm/huge_memory: vmf_insert_folio_*() and
vmf_insert_pfn_pud() fixes" from David Hildenbrand addresses some warts
which David noticed in the huge page code. These were not known to be
causing any issues at this time.
- The 3 patch series "mm/damon: use alloc_migrate_target() for
DAMOS_MIGRATE_{HOT,COLD" from SeongJae Park provides some cleanup and
consolidation work in DAMON.
- The 3 patch series "use vm_flags_t consistently" from Lorenzo Stoakes
uses vm_flags_t in places where we were inappropriately using other
types.
- The 3 patch series "mm/memfd: Reserve hugetlb folios before
allocation" from Vivek Kasireddy increases the reliability of large page
allocation in the memfd code.
- The 14 patch series "mm: Remove pXX_devmap page table bit and pfn_t
type" from Alistair Popple removes several now-unneeded PFN_* flags.
- The 5 patch series "mm/damon: decouple sysfs from core" from SeongJae
Park implememnts some cleanup and maintainability work in the DAMON
sysfs layer.
- The 5 patch series "madvise cleanup" from Lorenzo Stoakes does quite a
lot of cleanup/maintenance work in the madvise() code.
- The 4 patch series "madvise anon_name cleanups" from Vlastimil Babka
provides additional cleanups on top or Lorenzo's effort.
- The 11 patch series "Implement numa node notifier" from Oscar Salvador
creates a standalone notifier for NUMA node memory state changes.
Previously these were lumped under the more general memory on/offline
notifier.
- The 6 patch series "Make MIGRATE_ISOLATE a standalone bit" from Zi Yan
cleans up the pageblock isolation code and fixes a potential issue which
doesn't seem to cause any problems in practice.
- The 5 patch series "selftests/damon: add python and drgn based DAMON
sysfs functionality tests" from SeongJae Park adds additional drgn- and
python-based DAMON selftests which are more comprehensive than the
existing selftest suite.
- The 5 patch series "Misc rework on hugetlb faulting path" from Oscar
Salvador fixes a rather obscure deadlock in the hugetlb fault code and
follows that fix with a series of cleanups.
- The 3 patch series "cma: factor out allocation logic from
__cma_declare_contiguous_nid" from Mike Rapoport rationalizes and cleans
up the highmem-specific code in the CMA allocator.
- The 28 patch series "mm/migration: rework movable_ops page migration
(part 1)" from David Hildenbrand provides cleanups and
future-preparedness to the migration code.
- The 2 patch series "mm/damon: add trace events for auto-tuned
monitoring intervals and DAMOS quota" from SeongJae Park adds some
tracepoints to some DAMON auto-tuning code.
- The 6 patch series "mm/damon: fix misc bugs in DAMON modules" from
SeongJae Park does that.
- The 6 patch series "mm/damon: misc cleanups" from SeongJae Park also
does what it claims.
- The 4 patch series "mm: folio_pte_batch() improvements" from David
Hildenbrand cleans up the large folio PTE batching code.
- The 13 patch series "mm/damon/vaddr: Allow interleaving in
migrate_{hot,cold} actions" from SeongJae Park facilitates dynamic
alteration of DAMON's inter-node allocation policy.
- The 3 patch series "Remove unmap_and_put_page()" from Vishal Moola
provides a couple of page->folio conversions.
- The 4 patch series "mm: per-node proactive reclaim" from Davidlohr
Bueso implements a per-node control of proactive reclaim - beyond the
current memcg-based implementation.
- The 14 patch series "mm/damon: remove damon_callback" from SeongJae
Park replaces the damon_callback interface with a more general and
powerful damon_call()+damos_walk() interface.
- The 10 patch series "mm/mremap: permit mremap() move of multiple VMAs"
from Lorenzo Stoakes implements a number of mremap cleanups (of course)
in preparation for adding new mremap() functionality: newly permit the
remapping of multiple VMAs when the user is specifying MREMAP_FIXED. It
still excludes some specialized situations where this cannot be
performed reliably.
- The 3 patch series "drop hugetlb_free_pgd_range()" from Anthony Yznaga
switches some sparc hugetlb code over to the generic version and removes
the thus-unneeded hugetlb_free_pgd_range().
- The 4 patch series "mm/damon/sysfs: support periodic and automated
stats update" from SeongJae Park augments the present
userspace-requested update of DAMON sysfs monitoring files. Automatic
update is now provided, along with a tunable to control the update
interval.
- The 4 patch series "Some randome fixes and cleanups to swapfile" from
Kemeng Shi does what is claims.
- The 4 patch series "mm: introduce snapshot_page" from Luiz Capitulino
and David Hildenbrand provides (and uses) a means by which debug-style
functions can grab a copy of a pageframe and inspect it locklessly
without tripping over the races inherent in operating on the live
pageframe directly.
- The 6 patch series "use per-vma locks for /proc/pid/maps reads" from
Suren Baghdasaryan addresses the large contention issues which can be
triggered by reads from that procfs file. Latencies are reduced by more
than half in some situations. The series also introduces several new
selftests for the /proc/pid/maps interface.
- The 6 patch series "__folio_split() clean up" from Zi Yan cleans up
__folio_split()!
- The 7 patch series "Optimize mprotect() for large folios" from Dev
Jain provides some quite large (>3x) speedups to mprotect() when dealing
with large folios.
- The 2 patch series "selftests/mm: reuse FORCE_READ to replace "asm
volatile("" : "+r" (XXX));" and some cleanup" from wang lian does some
cleanup work in the selftests code.
- The 3 patch series "tools/testing: expand mremap testing" from Lorenzo
Stoakes extends the mremap() selftest in several ways, including adding
more checking of Lorenzo's recently added "permit mremap() move of
multiple VMAs" feature.
- The 22 patch series "selftests/damon/sysfs.py: test all parameters"
from SeongJae Park extends the DAMON sysfs interface selftest so that it
tests all possible user-requested parameters. Rather than the present
minimal subset.

* MTD changes:
Apart from a binding conversion to yaml, only minor changes/small fixes
have been merged.
* Raw NAND changes:
Various controller drivers received minor fixes like DMA mapping checks,
better timing derivations or bitflip statistics.
It has also been discovered that some Hynix NAND flashes were not
supporting read-retries, which is not properly supported.
* SPI NAND changes:
In order to support high-speed modes, certain chips need extra
configuration like adding more dummy cycles. This is now possible,
especially on Winbond chips.
Aside from that, Gigadevice gets support for a new chip (GD5F1GM9).
* SPI NOR changes:
A notable changes is the fix for exiting 4-byte addressing on Infineon
SEMPER flashes. These flashes do not support the standard EX4B
opcode (E9h), and use a vendor-specific opcode (B8h) instead.
There is also a fix for unlocking flashes that are write-protected at
power-on. This was caused by using an uninitialized mtd_info in
spi_nor_try_unlock_all().

This is the usual collection of primarily clk driver updates. The big part of
the diff is all the new Qualcomm clk drivers added for a few SoCs they're
working on. The other two vendors with significant work this cycle are Renesas
and Amlogic. Renesas adds a bunch of clks to existing drivers and supports some
new SoCs while Amlogic is starting a significant refactoring to simplify their
code.
The core framework gained a pair of helpers to get the 'struct device' or
'struct device_node' associated with a 'struct clk_hw'. Some associated KUnit
tests were added for these simple helpers as well. Beyond that core change
there are lots of little fixes throughout the clk drivers for the stuff we see
every day, wrong clk driver data that affects tree topology or supported
frequencies, etc. They're not found until the clks are actually used by some
consumer device driver.
New Drivers:
- Global, display, gpu, video, camera, tcsr, and rpmh clock controller for the
Qualcomm Milos SoC
- Camera, display, GPU, and video clock controllers for Qualcomm QCS615
- Video clock controller driver for Qualcomm SM6350
- Camera clock controller driver for Qualcomm SC8180X
- I3C clocks and resets on Renesas RZ/G3E
- Expanded Serial Peripheral Interface (xSPI) clocks and resets on
Renesas RZ/V2H(P) and RZ/V2N
- SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
- SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
- Ethernet clocks and resets on Renesas RZ/G3E
- Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
(R9A09G087) SoCs
- Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
- Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas
RZ/V2N
Updates:
- Support atomic PWMs in the PWM clk driver
- clk_hw_get_dev() and clk_hw_get_of_node() helpers
- Replace round_rate() with determine_rate() in various clk drivers
- Convert clk DT bindings to DT schema format for DT validation
- Various clk driver cleanups and refactorings from static analysis tools and
possibly real humans
- A lot of little fixes here and there to things like clk tree topology,
missing frequencies, flagging clks as critical, etc. The full details are in
the commits and sub-tree merge logs

iommufd 6.17 merge window pull
- IOMMU HW now has features to directly assign HW command queues to a
guest VM. In this mode the command queue operates on a limited set of
invalidation commands that are suitable for improving guest invalidation
performance and easy for the HW to virtualize.
This PR brings the generic infrastructure to allow IOMMU drivers to
expose such command queues through the iommufd uAPI, mmap the doorbell
pages, and get the guest physical range for the command queue ring
itself.
- An implementation for the NVIDIA SMMUv3 extension "cmdqv" is built on
the new iommufd command queue features. It works with the existing SMMU
driver support for cmdqv in guest VMs.
- Many precursor cleanups and improvements to support the above cleanly,
changes to the general ioctl and object helpers, driver support for
VDEVICE, and mmap pgoff cookie infrastructure.
- Sequence VDEVICE destruction to always happen before VFIO device
destruction. When using the above type features, and also in future
confidential compute, the internal virtual device representation becomes
linked to HW or CC TSM configuration and objects. If a VFIO device is
removed from iommufd those HW objects should also be cleaned up to
prevent a sort of UAF. This became important now that we have HW backing
the VDEVICE.
- Fix one syzkaller found error related to math overflows during iova
allocation

"This broadly brings the assigned HW command queue support to iommufd.
This feature is used to improve SVA performance in VMs by avoiding
paravirtualization traps during SVA invalidations.

doorbell pages, and get the guest physical range for the command
queue ring itself.
- An implementation for the NVIDIA SMMUv3 extension "cmdqv" is built
on the new iommufd command queue features. It works with the
existing SMMU driver support for cmdqv in guest VMs.
- Many precursor cleanups and improvements to support the above
cleanly, changes to the general ioctl and object helpers, driver
support for VDEVICE, and mmap pgoff cookie infrastructure.
- Sequence VDEVICE destruction to always happen before VFIO device
destruction. When using the above type features, and also in future
confidential compute, the internal virtual device representation
becomes linked to HW or CC TSM configuration and objects. If a VFIO
device is removed from iommufd those HW objects should also be
cleaned up to prevent a sort of UAF. This became important now that
we have HW backing the VDEVICE.
- Fix one syzkaller found error related to math overflows during iova
allocation"

LEDs for for v6.17
- Improvements & Fixes
* A fix has been implemented in QCOM Flash to prevent incorrect register
access when the driver is re-bound. This is solved by duplicating a static
register array during the probe function, which prevents register addresses
from being miscalculated after multiple binds.
* The LP50xx driver now correctly handles the 'reg' property in device tree
child nodes to ensure the multi_index is set correctly. This prevents
issues where LEDs could be controlled incorrectly if the device tree nodes
were processed in a different order. An error is returned if the reg
property is missing or out of range.
* A Kconfig dependency on between TPS6131x and V4L2_FLASH_LED_CLASS has been
added to prevent a build failure when the driver is built-in and the V4L2
flash infrastructure is a loadable module.
* A potential buffer overflow warning in PCA955x was reported by older GCC
versions has been fixed by using a more precise format specifier when
creating the default LED label.
- Cleanups & Refactoring
* The MAINTAINERS file entry for the TPS6131X flash LED driver has been
corrected to point to the correct device tree binding file name.
* A comment in the Flash Class for the flash_timeout setter has been
corrected to "flash timeout" from "flash duration" for accuracy.
* The of_led_get() function is no longer exported as it has no users
outside of its own module.
- Removals
* The commit to configure LED blink intervals for hardware offload in the
Netdev Trigger has been reverted. This change was found to break existing
PHY drivers by putting their LEDs into a permanent, unconditional blinking
state.
- Device Tree Bindings Updates
* The binding for LP50xx has been updated to document that the child reg
property is the index within the LED bank. The example was also updated to
use correct values.
* The JNCP5623 binding has been updated to add 0x39 as a valid I2C address,
as it is used by the NCP5623C variant.

It has been a relatively busy cycle for docs, especially the build system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the turn of
the millennium. Over the following 25 years, it accumulated a vast
amount of cruft, all in a language few people want to deal with anymore.
Mauro's Python replacement in 6.16 faithfully reproduced all of the cruft
in the hope of avoiding regressions. Now that we have a more reasonable
code base, though, we can work on cleaning it up; many of the changes
this time around are toward that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository links.
...and lots of fixes and updates.

bitfield: Ensure the return values of helper functions are checked
As type##_replace_bits() has no side effects it is only useful if its return value is checked. Add __must_check to enforce this usage. To have the bits replaced in-place typep##_replace_bits() can be used instead. Although, type_##_get_bits() and type_##_encode_bits() are harder to misuse they are still only useful if the return value is checked. For consistency, also add __must_check to these.

In an upcoming change, the non-asm GENMASK*() will all be unified to depend on GENMASK_TYPE() which indirectly depend on sizeof(), something not available in asm.

cpumask: Remove unnecessary cpumask_nth_andnot()
Commit 94f753143028("x86/resctrl: Optimize cpumask_any_housekeeping()")
switched the only user of cpumask_nth_andnot() to other cpumask
functions, but left the function cpumask_nth_andnot() unused.
This makes function find_nth_andnot_bit() unused as well. Delete them.

ARM:
- Host driver for GICv5, the next generation interrupt controller for arm64, including support for interrupt routing, MSIs, interrupt translation and wired interrupts. - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on GICv5 hardware, leveraging the legacy VGIC interface. - Userspace control of the 'nASSGIcap' GICv3 feature, allowing userspace to disable support for SGIs w/o an active state on hardware that previously advertised it unconditionally. - Map supporting endpoints with cacheable memory attributes on systems with FEAT_S2FWB and DIC where KVM no longer needs to perform cache maintenance on the address range. - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest hypervisor to inject external aborts into an L2 VM and take traps of masked external aborts to the hypervisor. - Convert more system register sanitization to the config-driven implementation. - Fixes to the visibility of EL2 registers, namely making VGICv3 system registers accessible through the VGIC device instead of the ONE_REG vCPU ioctls. - Various cleanups and minor fixes. LoongArch: - Add stat information for in-kernel irqchip - Add tracepoints for CPUCFG and CSR emulation exits - Enhance in-kernel irqchip emulation - Various cleanups. RISC-V: - Enable ring-based dirty memory tracking - Improve perf kvm stat to report interrupt events - Delegate illegal instruction trap to VS-mode - MMU improvements related to upcoming nested virtualization s390x - Fixes x86: - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC, PIC, and PIT emulation at compile time. - Share device posted IRQ code between SVM and VMX and harden it against bugs and runtime errors. - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1) instead of O(n). - For MMIO stale data mitigation, track whether or not a vCPU has access to (host) MMIO based on whether the page tables have MMIO pfns mapped; using VFIO is prone to false negatives - Rework the MSR interception code so that the SVM and VMX APIs are more or less identical. - Recalculate all MSR intercepts from scratch on MSR filter changes, instead of maintaining shadow bitmaps. - Advertise support for LKGS (Load Kernel GS base), a new instruction that's loosely related to FRED, but is supported and enumerated independently. - Fix a user-triggerable WARN that syzkaller found by setting the vCPU in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU into VMX Root Mode (post-VMXON). Trying to detect every possible path leading to architecturally forbidden states is hard and even risks breaking userspace (if it goes from valid to valid state but passes through invalid states), so just wait until KVM_RUN to detect that the vCPU state isn't allowed. - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of APERF/MPERF reads, so that a "properly" configured VM can access APERF/MPERF. This has many caveats (APERF/MPERF cannot be zeroed on vCPU creation or saved/restored on suspend and resume, or preserved over thread migration let alone VM migration) but can be useful whenever you're interested in letting Linux guests see the effective physical CPU frequency in /proc/cpuinfo. - Reject KVM_SET_TSC_KHZ for vm file descriptors if vCPUs have been created, as there's no known use case for changing the default frequency for other VM types and it goes counter to the very reason why the ioctl was added to the vm file descriptor. And also, there would be no way to make it work for confidential VMs with a "secure" TSC, so kill two birds with one stone. - Dynamically allocation the shadow MMU's hashed page list, and defer allocating the hashed list until it's actually needed (the TDP MMU doesn't use the list). - Extract many of KVM's helpers for accessing architectural local APIC state to common x86 so that they can be shared by guest-side code for Secure AVIC. - Various cleanups and fixes. x86 (Intel): - Preserve the host's DEBUGCTL.FREEZE_IN_SMM when running the guest. Failure to honor FREEZE_IN_SMM can leak host state into guests. - Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter to prevent L1 from running L2 with features that KVM doesn't support, e.g. BTF. x86 (AMD): - WARN and reject loading kvm-amd.ko instead of panicking the kernel if the nested SVM MSRPM offsets tracker can't handle an MSR (which is pretty much a static condition and therefore should never happen, but still). - Fix a variety of flaws and bugs in the AVIC device posted IRQ code. - Inhibit AVIC if a vCPU's ID is too big (relative to what hardware supports) instead of rejecting vCPU creation. - Extend enable_ipiv module param support to SVM, by simply leaving IsRunning clear in the vCPU's physical ID table entry. - Disable IPI virtualization, via enable_ipiv, if the CPU is affected by erratum #1235, to allow (safely) enabling AVIC on such CPUs. - Request GA Log interrupts if and only if the target vCPU is blocking, i.e. only if KVM needs a notification in order to wake the vCPU. - Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to the vCPU's CPUID model. - Accept any SNP policy that is accepted by the firmware with respect to SMT and single-socket restrictions. An incompatible policy doesn't put the kernel at risk in any way, so there's no reason for KVM to care. - Drop a superfluous WBINVD (on all CPUs!) when destroying a VM and use WBNOINVD instead of WBINVD when possible for SEV cache maintenance. - When reclaiming memory from an SEV guest, only do cache flushes on CPUs that have ever run a vCPU for the guest, i.e. don't flush the caches for CPUs that can't possibly have cache lines with dirty, encrypted data. Generic: - Rework irqbypass to track/match producers and consumers via an xarray instead of a linked list. Using a linked list leads to O(n^2) insertion times, which is hugely problematic for use cases that create large numbers of VMs. Such use cases typically don't actually use irqbypass, but eliminating the pointless registration is a future problem to solve as it likely requires new uAPI. - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a "void *", to avoid making a simple concept unnecessarily difficult to understand. - Decouple device posted IRQs from VFIO device assignment, as binding a VM to a VFIO group is not a requirement for enabling device posted IRQs. - Clean up and document/comment the irqfd assignment code. - Disallow binding multiple irqfds to an eventfd with a priority waiter, i.e. ensure an eventfd is bound to at most one irqfd through the entire host, and add a selftest to verify eventfd:irqfd bindings are globally unique. - Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues related to private <=> shared memory conversions. - Drop guest_memfd's .getattr() implementation as the VFS layer will call generic_fillattr() if inode_operations.getattr is NULL. - Fix issues with dirty ring harvesting where KVM doesn't bound the processing of entries in any way, which allows userspace to keep KVM in a tight loop indefinitely. - Kill off kvm_arch_{start,end}_assignment() and x86's associated tracking, now that KVM no longer uses assigned_device_count as a heuristic for either irqbypass usage or MDS mitigation. Selftests: - Fix a comment typo. - Verify KVM is loaded when getting any KVM module param so that attempting to run a selftest without kvm.ko loaded results in a SKIP message about KVM not being loaded/enabled (versus some random parameter not existing). - Skip tests that hit EACCES when attempting to access a file, and rpint a "Root required?" help message. In most cases, the test just needs to be run with elevated permissions. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmiKXMgUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroMhMQf/QDhC/CP1aGXph2whuyeD2NMqPKiU 9KdnDNST+ftPwjg9QxZ9mTaa8zeVz/wly6XlxD9OQHy+opM1wcys3k0GZAFFEEQm YrThgURdzEZ3nwJZgb+m0t4wjJQtpiFIBwAf7qq6z1VrqQBEmHXJ/8QxGuqO+BNC j5q/X+q6KZwehKI6lgFBrrOKWFaxqhnRAYfW6rGBxRXxzTJuna37fvDpodQnNceN zOiq+avfriUMArTXTqOteJNKU0229HjiPSnjILLnFQ+B3akBlwNG0jk7TMaAKR6q IZWG1EIS9q1BAkGXaw6DE1y6d/YwtXCR5qgAIkiGwaPt5yj9Oj6kRN2Ytw== =j2At -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "ARM: - Host driver for GICv5, the next generation interrupt controller for arm64, including support for interrupt routing, MSIs, interrupt translation and wired interrupts - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on GICv5 hardware, leveraging the legacy VGIC interface - Userspace control of the 'nASSGIcap' GICv3 feature, allowing userspace to disable support for SGIs w/o an active state on hardware that previously advertised it unconditionally - Map supporting endpoints with cacheable memory attributes on systems with FEAT_S2FWB and DIC where KVM no longer needs to perform cache maintenance on the address range - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest hypervisor to inject external aborts into an L2 VM and take traps of masked external aborts to the hypervisor - Convert more system register sanitization to the config-driven implementation - Fixes to the visibility of EL2 registers, namely making VGICv3 system registers accessible through the VGIC device instead of the ONE_REG vCPU ioctls - Various cleanups and minor fixes LoongArch: - Add stat information for in-kernel irqchip - Add tracepoints for CPUCFG and CSR emulation exits - Enhance in-kernel irqchip emulation - Various cleanups RISC-V: - Enable ring-based dirty memory tracking - Improve perf kvm stat to report interrupt events - Delegate illegal instruction trap to VS-mode - MMU improvements related to upcoming nested virtualization s390x - Fixes x86: - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC, PIC, and PIT emulation at compile time - Share device posted IRQ code between SVM and VMX and harden it against bugs and runtime errors - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1) instead of O(n) - For MMIO stale data mitigation, track whether or not a vCPU has access to (host) MMIO based on whether the page tables have MMIO pfns mapped; using VFIO is prone to false negatives - Rework the MSR interception code so that the SVM and VMX APIs are more or less identical - Recalculate all MSR intercepts from scratch on MSR filter changes, instead of maintaining shadow bitmaps - Advertise support for LKGS (Load Kernel GS base), a new instruction that's loosely related to FRED, but is supported and enumerated independently - Fix a user-triggerable WARN that syzkaller found by setting the vCPU in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU into VMX Root Mode (post-VMXON).

Remove or hide unused tracepoints
Tracepoints take up memory (around 5K per tracepoint) even when they are
unused. Changes are being made to detect when a tracepoint is defined but
unused and a warning is shown at build. But those changes are not yet
ready for inclusion.
- Fix some of the unused tracepoints that it detected
Some tracepoints were removed and others were hidden by config settings
to match the config settings of where they are instantiated. Some
tracepoints were moved into architecture specific code as only one
architecture used them.
- Call the ftrace_test_filter tracepoint in an unreachable if statement
The ftrace_test_filter tracepoint which is defined when ftrace selftests
are configured and is used to test the filter logic, but the tracepoint is
not actually called. It is put into an if statement to not have it get
compiled out, but also not warn for not being used.

Runtime verification changes for 6.17
- Added Linear temporal logic monitors for RT application
Real-time applications may have design flaws causing them to have
unexpected latency. For example, the applications may raise page faults, or
may be blocked trying to take a mutex without priority inheritance.
However, while attempting to implement DA monitors for these real-time
rules, deterministic automaton is found to be inappropriate as the
specification language. The automaton is complicated, hard to understand,
and error-prone.
For these cases, linear temporal logic is found to be more suitable. The
LTL is more concise and intuitive.
- Make printk_deferred() public
The new monitors needed access to printk_deferred(). Make them visible for
the entire kernel.
- Add a vpanic() to allow for va_list to be passed to panic.
- Add rtapp container monitor.
A collection of monitors that check for common problems with real-time
applications that cause unexpected latency.
- Add page fault tracepoints to risc-v
These tracepoints are necessary to for the RV monitor to run on risc-v.
- Fix the behaviour of the rv tool with -s and idle tasks.
- Allow the rv tool to gracefully terminate with SIGTERM
- Adjusts dot2c not to create lines over 100 columns
- Properly order nested monitors in the RV Kconfig file
- Return the registration error in all DA monitor instead of 0
- Update and add new sched collection monitors
Replace tss and sncid monitors with more complete sts:
Not only prove that switches occur in scheduling context and scheduling
needs interrupt disabled but also that each call to the scheduler
disables interrupts to (optionally) switch.
New monitor: nrp
Preemption requires need resched which is cleared by any switch
(includes a non optimal workaround for /nested/ preemptions)
New monitor: sssw
suspension requires setting the task to sleepable and, after the
switch occurs, the task requires a wakeup to come back to runnable
New monitor: opid
waking and need-resched operations occur with interrupts and
preemption disabled or in IRQ without explicitly disabling preemption

ring-buffer changes for v6.17:
- Rewind persistent ring buffer on boot When the persistent ring buffer is being used for live kernel tracing and the system crashes, the tool that is reading the trace may not have recorded the data when the system crashed. Although the persistent ring buffer still has that data, when reading it after a reboot, it will start where it left off. That is, what was read will not be accessible. Instead, on reboot, have the persistent ring buffer restart where the data starts and this will allow the tooling to recover what was lost when the crash occurred. - Remove the ring_buffer_read_prepare_sync() logic Reading the trace file required stopping writing to the ring buffer as the trace file is only an iterator and does not consume what it read. It was originally not safe to read the ring buffer in this mode and required disabling writing. The ring_buffer_read_prepare_sync() logic was used to stop each per_cpu ring buffer, call synchronize_rcu() and then start the iterator. This was used instead of calling synchronize_rcu() for each per_cpu buffer. Today, the iterator has been updated where it is safe to read the trace file while writing to the ring buffer is still occurring. There is no more need to do this synchronization and it is causing large delays on machines with many CPUs. Remove this unneeded synchronization. - Make static string array a constant in show_irq_str() Making the string array into a constant has shown to decrease code text/data size. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaIkfURQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qnx4AQCNXOuKYJXDvXrkwf449agwrn0lCVyI vV0L65nyIrakpAD8COV/lw8DhlCpb/Lijlzzo5L0n9QpEElNpq5uEntNwgE= =1YIy -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ring-buffer updates from Steven Rostedt: - Rewind persistent ring buffer on boot When the persistent ring buffer is being used for live kernel tracing and the system crashes, the tool that is reading the trace may not have recorded the data when the system crashed.

ftrace changes for v6.17:
- Keep track of when fgraph_ops are registered or not Keep accounting of when fgraph_ops are registered as if a fgraph_ops is registered twice it can mess up the accounting and it will not work as expected later. Trigger a warning if something registers it twice as to catch bugs before they are found by things just not working as expected. - Make DYNAMIC_FTRACE always enabled for architectures that support it As static ftrace (where all functions are always traced) is very expensive and only exists to help architectures support ftrace, do not make it an option. As soon as an architecture supports DYNAMIC_FTRACE make it use it. This simplifies the code. - Remove redundant config HAVE_FTRACE_MCOUNT_RECORD The CONFIG_HAVE_FTRACE_MCOUNT was added to help simplify the DYNAMIC_FTRACE work, but now every architecture that implements DYNAMIC_FTRACE also has HAVE_FTRACE_MCOUNT set too, making it redundant with the HAVE_DYNAMIC_FTRACE. - Make pid_ptr string size match the comment In print_graph_proc() the pid_ptr string is of size 11, but the comment says /* sign + log10(MAX_INT) + '\0' */ which is actually 12. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaIkVkRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qmdxAPsGcyT/gnyX/wf70cI63QoODrlRAd7M tg3R0J0H41U05QD/apttbA9GSdZ8bDLLSFAXTJgr8f4GvYvbUsmu2sMBBA8= =gd9V -----END PGP SIGNATURE----- Merge tag 'ftrace-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Keep track of when fgraph_ops are registered or not Keep accounting of when fgraph_ops are registered as if a fgraph_ops is registered twice it can mess up the accounting and it will not work as expected later.

Networking changes for 6.17.
Core & protocols
----------------
- Wrap datapath globals into net_aligned_data, to avoid false sharing.
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
- Add SO_INQ and SCM_INQ support to AF_UNIX.
- Add SIOCINQ support to AF_VSOCK.
- Add TCP_MAXSEG sockopt to MPTCP.
- Add IPv6 force_forwarding sysctl to enable forwarding per interface.
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB.
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users.
- Convert TCP send queue handling from tasklet to BH workque.
- Improve BPF iteration over TCP sockets to see each socket exactly once.
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel NAPI
thread when threaded NAPI gets disabled. Previously thread would stick
around until ifdown due to tricky synchronization.
- Allow multicast routing to take effect on locally-generated packets.
- Add output interface argument for End.X in segment routing.
- MCTP: add support for gateway routing, improve bind() handling.
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed.
- Support NUD_PERMANENT for proxy neighbor entries.
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
- Add sequence numbers to netconsole messages. Unregister netconsole's
console when all net targets are removed. Code refactoring.
Add a number of selftests.
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup.
- Support inspecting ref_tracker state via DebugFS.
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links.
- Allow providing upcall pid for the 'execute' command in openvswitch.
- Remove DCCP support from Netfilter's conntrack.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.
Driver API
----------
- Support RSS and hashing configuration over ethtool Netlink.
- Add dedicated ethtool callbacks for getting and setting hashing fields.
- Add support for power budget evaluation strategy in PSE /
Power-over-Ethernet. Generate Netlink events for overcurrent etc.
- Support DPLL phase offset monitoring across all device inputs.
Support providing clock reference and SYNC over separate DPLL
inputs.
- Support traffic classes in devlink rate API for bandwidth management.
- Remove rtnl_lock dependency from UDP tunnel port configuration.

mtd: spinand: winbond: Enable high-speed modes on w35n0xjw
w35n0xjw chips can run at up to 166MHz in octal mode, but this is only possible after programming various VCR registers. Implement the new ->configure_chip() hook for this purpose. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> |

mtd: spinand: winbond: Enable high-speed modes on w25n0xjw
w25n0xjw chips have a high-speed capability hidden in a configuration register. Once enabled, dual/quad SDR reads may be performed at a much higher frequency. Implement the new ->configure_chip() hook for this purpose and configure the SR4 register accordingly. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> |

mtd: spinand: Add a ->configure_chip() hook
There is already a manufacturer hook, which is manufacturer specific but not chip specific. We no longer have access to the actual NAND identity at this stage so let's add a per-chip configuration hook to align the chip configuration (if any) with the core's setting.

mtd: spinand: Add a frequency field to all READ_FROM_CACHE variants
These macros had initially no frequency field. When I added the "maximum operation frequency" field, I did it initially on very common macros and I decided to add an optional field for that (with VA_ARGS) in order to prevent massively unreadable changes. I then added new variants in the spinand.h header, and requested a frequency field for them by default. Some times later, I also added maximum frequencies to other existing variants, but I did it incorrectly, without noticing I was wrong because the field was optional. This mix is error prone, so let's do what I should have done since the very beginning: add a frequency field to all READ_FROM_CACHE variants. There is no functional change.
