dma-buf: heaps: cma: Register list of CMA regions at boot
In order to create a CMA heap instance for each CMA region found in the system, we need to register each of these instances. While it would appear trivial, the CMA regions are created super early in the kernel boot process, before most of the subsystems are initialized. Thus, we can't just create an exported function to create a heap from the CMA region being initialized. What we can do however is create a two-step process, where we collect all the CMA regions into an array early on, and then when we initialize the heaps we iterate over that array and create the heaps from the CMA regions we collected.

NFS4: Apply delay_retrans to async operations
The setting of delay_retrans is applied to synchronous RPC operations because the retransmit count is stored in same struct nfs4_exception that is passed each time an error is checked. However, for asynchronous operations (READ, WRITE, LOCKU, CLOSE, DELEGRETURN), a new struct nfs4_exception is made on the stack each time the task callback is invoked. This means that the retransmit count is always zero and thus delay_retrans never takes effect. Apply delay_retrans to these operations by tracking and updating their retransmit count.

KVM: guest_memfd: Allow mmap() on guest_memfd for x86 VMs with private memory
Allow mmap() on guest_memfd instances for x86 VMs with private memory as
the need to track private vs. shared state in the guest_memfd instance is
only pertinent to INIT_SHARED. Doing mmap() on private memory isn't
terrible useful (yet!), but it's now possible, and will be desirable when
guest_memfd gains support for other VMA-based syscalls, e.g. mbind() to
set NUMA policy.
Lift the restriction now, before MMAP support is officially released, so
that KVM doesn't need to add another capability to enumerate support for
mmap() on private memory.

tpm: use a map for tpm2_calc_ordinal_duration()
The current shenanigans for duration calculation introduce too much complexity for a trivial problem, and further the code is hard to patch and maintain. Address these issues with a flat look-up table, which is easy to understand and patch. If leaf driver specific patching is required in future, it is easy enough to make a copy of this table during driver initialization and add the chip parameter back. 'chip->duration' is retained for TPM 1.x. As the first entry for this new behavior address TCG spec update mentioned in this issue: https://github.com/raspberrypi/linux/issues/7054 Therefore, for TPM_SelfTest the duration is set to 3000 ms. This does not categorize a as bug, given that this is introduced to the spec after the feature was originally made.

VFIO updates for v6.18-rc1 part 2
- Optimizations for DMA map and unmap opertions through the type1
vfio IOMMU backend. This uses various means of batching and hints
from the mm structures to improve efficiency and therefore
performance, resulting in a significant speedup for huge page
use cases. (Li Zhe)
- Expose supported device migration features through debugfs.

Specifically, a VMA which has a valid pointer to vma->vm_userfaultfd_ctx, but no UFFD flags in vma->vm_flags. The inconsistency is caused in ksm_madvise(): when user calls madvise() with MADV_UNMEARGEABLE on a VMA that is registered for UFFD in MINOR mode, it accidentally clears all flags stored in the upper 32 bits of vma->vm_flags. Assuming x86_64 kernel build, unsigned long is 64-bit and unsigned int and int are 32-bit wide. This setup causes the following mishap during the &= ~VM_MERGEABLE assignment. VM_MERGEABLE is a 32-bit constant of type unsigned int, 0x8000'0000. After ~ is applied, it becomes 0x7fff'ffff unsigned int, which is then promoted to unsigned long before the & operation. This promotion fills upper 32 bits with leading 0s, as we're doing unsigned conversion (and even for a signed conversion, this wouldn't help as the leading bit is 0). & operation thus ends up AND-ing vm_flags with 0x0000'0000'7fff'ffff instead of intended 0xffff'ffff'7fff'ffff and hence accidentally clears the upper 32-bits of its value. Fix it by changing `VM_MERGEABLE` constant to unsigned long, using the BIT() macro. Note: other VM_* flags are not affected: This only happens to the VM_MERGEABLE flag, as the other VM_* flags are all constants of type int and after ~ operation, they end up with leading 1 and are thus converted to unsigned long with leading 1s.

memcg: skip cgroup_file_notify if spinning is not allowed
Generally memcg charging is allowed from all the contexts including NMI
where even spinning on spinlock can cause locking issues. However one
call chain was missed during the addition of memcg charging from any
context support. That is try_charge_memcg() -> memcg_memory_event() ->
cgroup_file_notify().
The possible function call tree under cgroup_file_notify() can acquire
many different spin locks in spinning mode. Some of them are
cgroup_file_kn_lock, kernfs_notify_lock, pool_workqeue's lock. So, let's
just skip cgroup_file_notify() from memcg charging if the context does not
allow spinning.
Alternative approach was also explored where instead of skipping
cgroup_file_notify(), we defer the memcg event processing to irq_work [1].
However it adds complexity and it was decided to keep things simple until
we need more memcg events with !allow_spinning requirement.

kho: add support for preserving vmalloc allocations
A vmalloc allocation is preserved using binary structure similar to global KHO memory tracker. It's a linked list of pages where each page is an array of physical address of pages in vmalloc area. kho_preserve_vmalloc() hands out the physical address of the head page to the caller. This address is used as the argument to kho_vmalloc_restore() to restore the mapping in the vmalloc address space and populate it with the preserved pages.

- 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

drop the existing "free" macro introduced for similar purpose, but
somewhat cumbersome to use (Rafael Wysocki)

marked as SYNC_STATE_ONLY which is consistent with the handling of
those device links elsewhere (Pin-yen Lin)

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. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEE9L57QeeUxqYDyoaDrQKIl8bklSUFAmjkoQAUHHN3Ym95ZEBj aHJvbWl1bS5vcmcACgkQrQKIl8bklSWfWBAA3cjpOX/qOBDPmYPvV+WgiTPcmnw+ PaMiGNqIWctnJiuYYUNVCfBIvTk9i1vYSgEosHAOqjXQV+7Ee31420xn5RYr6Zen cfeD58SJwZ1JVidvxwWclC5pnfTVXBC3wlHILCFHhckaGOT2k3d0ryN2io2TYuRx t9JsoW73YW+bmOWoFDHPMp4ow5Q87aa8k3/srhIP67tw2mzJp8Wp+EG0t0PVFF7Z aboz+QPwyT2YOLFKJxm6nTLb9FRVq3QLSO3Ek0+0TYXfRqkfegvGR+M82P4Jq2Y3 osmTsumWeI170iAETmx2Py+uUV8MmnvPFQ6mxrGoXYyOx9SclN+SC86cOsi+RsgD 830CHupZ/TrN3+DGyX6WVx1j7XKCplKhFXrXiFbkPnj4nJwi5UgiJrjAjPy78+iX LyvKfeT9ooAAVBVRMyZIWGF3kuQf5qHFMps5fwJk/j3R9yMiI10SVhruhYij1qAi EEisj955xqdyZV2gq85E7zHbjySA0nvNABn3NVUQOKPYQqtpglqXKGJuXZ1//9pa fZM2a3fH7w4fwH1x06FKut9zf1AZUgyasJPtgyCT9dpN+pcoNmJfoH3T42MCItbm XKEYgnv/kQT+M+GokBUfg8bJY5uPnPLa/f6aAAIAKGZV0HXAqz2q73SDlW7KUQmr vhgA4MRH4Vqviic= =fjY4 -----END PGP SIGNATURE----- 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.

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" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (299 commits) clk: microchip: core: remove duplicate roclk_determine_rate() reset: aspeed: register AST2700 reset auxiliary bus device dt-bindings: clock: ast2700: modify soc0/1 clock define clk: tegra: do not overallocate memory for bpmp clocks clk: ep93xx: Use int type to store negative error codes clk: nxp: Fix pll0 rate check condition in LPC18xx CGU driver clk: loongson2: Add clock definitions for Loongson-2K0300 SoC clk: loongson2: Avoid hardcoding firmware name of the reference clock clk: loongson2: Allow zero divisors for dividers clk: loongson2: Support scale clocks with an alternative mode clk: loongson2: Allow specifying clock flags for gate clock dt-bindings: clock: loongson2: Add Loongson-2K0300 compatible clk: clocking-wizard: Fix output clock register offset for Versal platforms clk: xilinx: Optimize divisor search in clk_wzrd_get_divisors_ver() clk: mmp: pxa1908: Instantiate power driver through auxiliary bus clk: s2mps11: add support for S2MPG10 PMIC clock dt-bindings: clock: samsung,s2mps11: add s2mpg10 dt-bindings: stm32: cosmetic fixes for STM32MP25 clock and reset bindings clk: stm32: introduce clocks for STM32MP21 platform dt-bindings: stm32: add STM32MP21 clocks and reset bindings ... |

NFSD 6.18 Release Notes
Mike Snitzer has prototyped a mechanism for disabling I/O caching in
NFSD. This is introduced in v6.18 as an experimental feature. This
enables scaling NFSD in /both/ directions:
- NFS service can be supported on systems with small memory
footprints, such as low-cost cloud instances
- Large NFS workloads will be less likely to force the eviction of
server-local activity, helping it avoid thrashing
Jeff Layton contributed a number of fixes to the new attribute
delegation implementation (based on a pending Internet RFC) that we
hope will make attribute delegation reliable enough to enable by
default, as it is on the Linux NFS client.
The remaining patches in this pull request are clean-ups and minor
optimizations. Many thanks to the contributors, reviewers, testers,
and bug reporters who participated during the v6.18 NFSD development
cycle.

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's 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.

page_pool: Fix PP_MAGIC_MASK to avoid crashing on some 32-bit arches
Helge reported that the introduction of PP_MAGIC_MASK let to crashes on
boot on his 32-bit parisc machine. The cause of this is the mask is set
too wide, so the page_pool_page_is_pp() incurs false positives which
crashes the machine.
Just disabling the check in page_pool_is_pp() will lead to the page_pool
code itself malfunctioning; so instead of doing this, this patch changes
the define for PP_DMA_INDEX_BITS to avoid mistaking arbitrary kernel
pointers for page_pool-tagged pages.
The fix relies on the kernel pointers that alias with the pp_magic field
always being above PAGE_OFFSET. With this assumption, we can use the
lowest bit of the value of PAGE_OFFSET as the upper bound of the
PP_DMA_INDEX_MASK, which should avoid the false positives.
Because we cannot rely on PAGE_OFFSET always being a compile-time
constant, nor on it always being >0, we fall back to disabling the
dma_index storage when there are not enough bits available. This leaves
us in the situation we were in before the patch in the Fixes tag, but
only on a subset of architecture configurations. This seems to be the
best we can do until the transition to page types in complete for
page_pool pages.
v2:
- Make sure there's at least 8 bits available and that the PAGE_OFFSET
bit calculation doesn't wrap

Merge tag 'pci-v6.18-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
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)"

mm: introduce num_pages_contiguous()
Let's add a simple helper for determining the number of contiguous pages that represent contiguous PFNs. In an ideal world, this helper would be simpler or not even required. Unfortunately, on some configs we still have to maintain (SPARSEMEM without VMEMMAP), the memmap is allocated per memory section, and we might run into weird corner cases of false positives when blindly testing for contiguous pages only. One example of such false positives would be a memory section-sized hole that does not have a memmap. The surrounding memory sections might get "struct pages" that are contiguous, but the PFNs are actually not. This helper will, for example, be useful for determining contiguous PFNs in a GUP result, to batch further operations across returned "struct page"s. VFIO will utilize this interface to accelerate the VFIO DMA map process. Implementation based on Linus' suggestions to avoid new usage of nth_page() where avoidable.
