Merge remote-tracking branch 'torvalds/master' into perf-tools

To pick up changes in other trees that may affect perf, such as libbpf
and in general the header files that perf has copies of, so that we can
do the sync with the kernel sources.

KVM/arm64 fixes for 6.12, take #1

- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

ASoC: Fixes for v6.12

A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.

Merge tag 'pci-v6.12-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Wait for device readiness after reset by polling Vendor ID and
looking for Configuration RRS instead of polling the Command
register and looking for non-error completions, to avoid hardware
retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)

- Rename CRS Completion Status to RRS ('Request Retry Status') to
match PCIe r6.0 spec usage (Bjorn Helgaas)

- Clear LBMS bit after a manual link retrain so we don't try to
retrain a link when there's no downstream device anymore (Maciej W.
Rozycki)

- Revert to the original link speed after retraining fails instead of
leaving it restricted to 2.5GT/s, so a future device has a chance
to use higher speeds (Maciej W. Rozycki)

- Wait for each level of downstream bus, not just the first, to
become accessible before restoring devices on that bus (Ilpo
Järvinen)

- Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
without having to stomp on the core's pdev->dev.groups (Lukas
Wunner)

Driver binding:

- Export pcim_request_region(), a managed counterpart of
pci_request_region(), for use by drivers (Philipp Stanner)

- Export pcim_iomap_region() and deprecate pcim_iomap_regions()
(Philipp Stanner)

- Request the PCI BAR used by xboxvideo (Philipp Stanner)

- Request and map drm/ast BARs with pcim_iomap_region() (Philipp
Stanner)

MSI:

- Add MSI_FLAG_NO_AFFINITY flag for devices that mux MSIs onto a
single IRQ line and cannot set the affinity of each MSI to a
specific CPU core (Marek Vasut)

- Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'
warnings (Marek Vasut)

Power management:

- Add pwrctl support for ATH11K inside the WCN6855 package (Konrad
Dybcio)

PCI device hotplug:

- Remove unnecessary hpc_ops struct from shpchp (ngn)

- Check for PCI_POSSIBLE_ERROR(), not 0xffffffff, in cpqphp
(weiyufeng)

Virtualization:

- Mark Creative Labs EMU20k2 INTx masking as broken (Alex Williamson)

- Add an ACS quirk for Qualcomm SA8775P, which doesn't advertise ACS
but does provide ACS-like features (Subramanian Ananthanarayanan)

IOMMU:

- Add function 0 DMA alias quirk for Glenfly Arise audio function,
which uses the function 0 Requester ID (WangYuli)

NPEM:

- Add Native PCIe Enclosure Management (NPEM) support for sysfs
control of NVMe RAID storage indicators (ok/fail/locate/
rebuild/etc) (Mariusz Tkaczyk)

- Add support for the ACPI _DSM PCIe SSD status LED management, which
is functionally similar to NPEM but mediated by platform firmware
(Mariusz Tkaczyk)

Device trees:

- Drop minItems and maxItems from ranges in PCI generic host binding
since host bridges may have several MMIO and I/O port apertures
(Frank Li)

clocks (Krzysztof Kozlowski)

Altera PCIe controller driver:

- Convert altera DT bindings from text to YAML (Matthew Gerlach)

- Replace TLP_REQ_ID() with macro PCI_DEVID(), which does the same
thing and is what other drivers use (Jinjie Ruan)

Broadcom STB PCIe controller driver:

- Add DT binding maxItems for reset controllers (Jim Quinlan)

- Use the 'bridge' reset method if described in the DT (Jim Quinlan)

- Use the 'swinit' reset method if described in the DT (Jim Quinlan)

- Add 'has_phy' so the existence of a 'rescal' reset controller
doesn't imply software control of it (Jim Quinlan)

- Add support for many inbound DMA windows (Jim Quinlan)

- Rename SoC 'type' to 'soc_base' express the fact that SoCs come in
families of multiple similar devices (Jim Quinlan)

- Add Broadcom 7712 DT description and driver support (Jim Quinlan)

- Sort enums, pcie_offsets[], pcie_cfg_data, .compatible strings for

- Fix i.MX8MP Endpoint occasional failure to trigger MSI by enforcing
outbound alignment requirement (Richard Zhu)

supported (Frank Li)

statements (Frank Li)

- Manage core reset by using SoC-specific callbacks instead of switch
statements (Frank Li)

- Expand comments for erratum ERR010728 workaround (Frank Li)

- Use generic PHY APIs to configure mode, speed, and submode, which
is harmless for devices that implement their own internal PHY
management and don't set the generic imx_pcie->phy (Frank Li)

- Add i.MX8Q (i.MX8QM, i.MX8QXP, and i.MX8DXL) DT binding and driver
Root Complex support (Richard Zhu)

Freescale Layerscape PCIe controller driver:

- Replace layerscape-pcie DT binding compatible fsl,lx2160a-pcie with

PCI: Rename CRS Completion Status to RRS

PCIe r6.0 changed the abbreviation for "Configuration Request Retry Status"
Completion Status from "CRS" to "RRS" and uses the terminology of
"Configuration RRS Software Visibility" instead of "CRS Software
Visibility".

Align the Linux usage with the r6.0 spec language. No functional change
intended.

It's confusing to make this change, but I think "RRS" *is* a better
abbreviation because it was easy to interpret "CRS" as "Completion Retry
Status", which really didn't make any sense.

Merge tag 'pci-v6.1-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull pci updates from Bjorn Helgaas:
"Resource management:

- Distribute spare resources to unconfigured hotplug bridges at
boot-time (not just when hot-adding such a bridge), which makes
hot-adding devices to docks work better.

- Revert to a BAR assignment inherited from firmware only when the
address is actually reachable via any upstream bridges, which fixes
some cases where firmware doesn't configure all devices.

- Add a sysfs interface to resize BARs so this can be done before
assigning devices to a VM through VFIO.

Power management:

- Disable Precision Time Management for all devices on suspend to
enable lower-power PM state. We previously did this just for Root
Ports, which isn't enough because downstream devices can still
generate PTM messages, which cause errors if it's disabled in the
Root Port.

- Save and restore the ASPM L1 PM Substates configuration for
suspend/ resume. Previously this configuration was lost, so L1.x
states likely stopped working after resume.

- Check whether the L1 PM Substates Capability exists. If it didn't
exist, we previously read junk and tried to configure L1 Substates
based on that.

- Fix the LTR_L1.2_THRESHOLD computation, which previously set a
threshold for entering L1.2 that was too low in some cases.

- Reduce the delay after transitions to or from D3cold by using
usleep_range() rather than msleep(), which often slept for ~19ms
instead of the 10ms normally required. The spec says 10ms is
enough, but it's possible we could trip over devices that need a
little more.

Error handling:

- Work around a BIOS bug that caused Intel Root Ports to advertise a
Root Port Programmed I/O (RP PIO) log size of zero, which caused
annoying warnings and prevented the kernel from dumping log
registers for DPC errors.

Qualcomm PCIe controller driver:

- Add support for SC8280XP and SA8540P host controllers and SM8450
endpoint controller.

- Disable Master AXI clock on endpoint controllers to save power when
link is idle or in L1.x.

- Expose link state transition counts via debugfs to help debug
issues with low-power states.

- Add auto-loading module support.

Synopsys DesignWare PCIe controller driver:

- Remove a dependency on ZONE_DMA32 by allocating the MSI target page
differently. There's more work to do related to eDMA controllers,
so it's not completely settled"

PCI: pci-bridge-emul: Set position of PCI capabilities to real HW value

mvebu and aardvark HW have PCIe capabilities on different offset in PCI
config space. Extend pci-bridge-emul.c code to allow setting custom driver
custom value where PCIe capabilities starts.

With this change PCIe capabilities of both drivers are reported at the same
location as where they are reported by U-Boot - in their real HW offset.
