usb: dwc3: imx: avoid calling imx suspend/resume callbacks twice
If a runtime suspend is executed followed by a system suspend, the driver
may invoke dwc3_imx_suspend() twice, which causes enable_irq() to be
called twice as well. This leads to an unbalanced IRQ state and may
trigger warnings or malfunction. Prevent this by checking the pm_suspended
flag before running the imx suspend/resume path.

tcpm: Implement sink support for PD SPR AVS negotiation
Add support to enable TCPM to negotiate with USB PD Standard Power Range Adjustable Voltage Supply (SPR AVS) when acting as a power sink. * Added support to the tcpm power supply properties, allowing userspace to enable and control the dynamic limits (voltage and current) specific to the SPR AVS contract. * Implemented tcpm_pd_select_spr_avs_apdo() to select the appropriate APDO and validate the requested voltage/current against both the Source and Sink capabilities. * Implemented tcpm_pd_build_spr_avs_request() to construct the Request Data Object (RDO) for SPR AVS. * Added SNK_NEGOTIATE_SPR_AVS_CAPABILITIES state to the state machine to handle negotiation for SPR AVS. * Updated the SNK_TRANSITION_SINK state to implement the SPR AVS-specific VBUS transition rules, including reducing current draw to PD_I_SNK_STBY_MA for large voltage changes, as required by USB PD spec.

usb: port: add delay after usb_hub_set_port_power()
When a port is disabled, an attached device will be disconnected. This
causes a port-status-change event, which will race with hub autosuspend
(if the disabled port was the only connected port on its hub), causing
an immediate resume and a second autosuspend. Both of these can be
avoided by adding a short delay after the call to
usb_hub_set_port_power().
Below log shows what is happening:
$ echo 1 > usb1-port1/disable
[ 37.958239] usb 1-1: USB disconnect, device number 2
[ 37.964101] usb 1-1: unregistering device

[ 38.457429] usb 1-1: new high-speed USB device number 3 using ci_hdrc
Then, port change bit will be fixed to the final state and
usb_clear_port_feature() can correctly clear it after this period. This
will also avoid usb runtime suspend routine to run because
usb_autopm_put_interface() not run yet.

usb: core: allow ACPI-managed hard-wired ports to power off
USB core only relaxes the default PM_QOS_FLAG_NO_POWER_OFF policy when an upstream hub reports switchable port power. That misses internal ports whose power is managed by platform firmware instead of the USB hub descriptor. Allow the port-poweroff policy to be exposed for hard-wired ports with an ACPI-managed power resource. The existing runtime PM path still requires the child usage count to drop and remote wakeup to be clear before it will power the port down. This lets internal devices such as CNVi Bluetooth use the existing USB ACPI runtime power path even when the root hub reports no USB-standard port power switching.

ARM:
- Correctly handle deeactivation of interrupts that were activated from
LRs. Since EOIcount only denotes deactivation of interrupts that
are not present in an LR, start EOIcount deactivation walk *after*
the last irq that made it into an LR.
- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when
pKVM is already enabled -- not only thhis isn't possible (pKVM
will reject the call), but it is also useless: this can only
happen for a CPU that has already booted once, and the capability
will not change.
- Fix a couple of low-severity bugs in our S2 fault handling path,
affecting the recently introduced LS64 handling and the even more
esoteric handling of hwpoison in a nested context
- Address yet another syzkaller finding in the vgic initialisation,
where we would end-up destroying an uninitialised vgic with nasty
consequences
- Address an annoying case of pKVM failing to boot when some of the
memblock regions that the host is faulting in are not page-aligned
- Inject some sanity in the NV stage-2 walker by checking the limits
against the advertised PA size, and correctly report the resulting
faults
PPC:
- Fix a PPC e500 build error due to a long-standing wart that was exposed by
the recent conversion to kmalloc_obj(); rip out all the ugliness that
led to the wart.
RISC-V:
- Prevent speculative out-of-bounds access using array_index_nospec()
in APLIC interrupt handling, ONE_REG regiser access, AIA CSR access,
float register access, and PMU counter access
- Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(),
kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr()
- Fix potential null pointer dereference in kvm_riscv_vcpu_aia_rmw_topei()
- Fix off-by-one array access in SBI PMU
- Skip THP support check during dirty logging
- Fix error code returned for Smstateen and Ssaia ONE_REG interface
- Check host Ssaia extension when creating AIA irqchip
x86:
- Fix cases where CPUID mitigation features were incorrectly marked as
available whenever the kernel used scattered feature words for them.
- Validate _all_ GVAs, rather than just the first GVA, when processing
a range of GVAs for Hyper-V's TLB flush hypercalls.
- Fix a brown paper bug in add_atomic_switch_msr().
- Use hlist_for_each_entry_srcu() when traversing mask_notifier_list,
to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu.
- Ensure AVIC VMCB fields are initialized if the VM has an in-kernel local
APIC (and AVIC is enabled at the module level).
- Update CR8 write interception when AVIC is (de)activated, to fix a bug
where the guest can run in perpetuity with the CR8 intercept enabled.
- Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to allow
L1 hypervisors to set FREEZE_IN_SMM. This reverts (by default) an
unintentional tightening of userspace ABI in 6.17, and provides some
amount of backwards compatibility with hypervisors who want to freeze
PMCs on VM-Entry.
- Validate the VMCS/VMCB on return to a nested guest from SMM, because
either userspace or the guest could stash invalid values in memory
and trigger the processor's consistency checks.
Generic:
- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being
unnecessary and confusing, triggered compiler warnings due to
-Wflex-array-member-not-at-end.
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite being
rather unintuitive.
Selftests:
- Increase the maximum number of NUMA nodes in the guest_memfd selftest to
64 (from 8).

Pull kvm fixes from Paolo Bonzini:
"Quite a large pull request, partly due to skipping last week and
therefore having material from ~all submaintainers in this one. About
a fourth of it is a new selftest, and a couple more changes are large
in number of files touched (fixing a -Wflex-array-member-not-at-end
compiler warning) or lines changed (reformatting of a table in the API
documentation, thanks rST).
But who am I kidding---it's a lot of commits and there are a lot of
bugs being fixed here, some of them on the nastier side like the
RISC-V ones.

More MM-CID fixes, mostly fixing hangs/races:
- Fix CID hangs due to a race between concurrent forks
- Fix vfork()/CLONE_VM MMCID bug causing hangs
- Remove pointless preemption guard
- Fix CID task list walk performance regression on large systems
by removing the known-flaky and slow counting logic using
for_each_process_thread() in mm_cid_*fixup_tasks_to_cpus(),
and implementing a simple sched_mm_cid::node list instead

Pull scheduler fixes from Ingo Molnar:
"More MM-CID fixes, mostly fixing hangs/races:
- Fix CID hangs due to a race between concurrent forks
- Fix vfork()/CLONE_VM MMCID bug causing hangs
- Remove pointless preemption guard
- Fix CID task list walk performance regression on large systems
by removing the known-flaky and slow counting logic using
for_each_process_thread() in mm_cid_*fixup_tasks_to_cpus(), and
implementing a simple sched_mm_cid::node list instead"

Rust fixes for v7.0 (2nd)
Toolchain and infrastructure:
- Remap paths to avoid absolute ones starting with the upcoming Rust
1.95.0 release. This improves build reproducibility, avoids leaking
the exact path and avoids having the same path appear in two forms.
The approach here avoids remapping debug information as well, in
order to avoid breaking tools that used the paths to access source
files, which was the previous attempt that needed to be reverted.
- Allow 'unused_features' lint for the upcoming Rust 1.96.0 release.
While well-intentioned, we do not benefit much from the new lint.
- Emit dependency information into '$(depfile)' directly to avoid
a temporary '.d' file (it was an old approach).
'kernel' crate:
- 'str' module: fix warning under '!CONFIG_BLOCK' by making
'NullTerminatedFormatter' public.
- 'cpufreq' module: suppress false positive Clippy warning.
'pin-init' crate:
- Remove '#[disable_initialized_field_access]' attribute which was
unsound. This means removing the support for structs with unaligned
fields (through the 'repr(packed)' attribute), for now.
And document the load-bearing fact of field accessors (i.e. that they
are required for soundness).
- Replace shadowed return token by 'unsafe'-to-create token in order
to remain sound in the face of the likely upcoming Type Alias Impl
Trait (TAIT) and the next trait solver in upstream Rust.

USB fixes for 7.0-rc4
Here is a large chunk of USB driver fixes for 7.0-rc4. Included in here
are:
- usb gadget reverts due to reported issues, and then a follow-on fix
to hopefully resolve the reported overall problem
- xhci driver fixes
- dwc3 driver fixes
- usb core "killable" bulk message api addition to fix a usbtmc driver
bug where userspace could hang the driver for forever
- small USB driver fixes for reported issues
- new usb device quirks
All except the last USB device quirk change have been in linux-next with
no reported issues. That one came in too late, and is "obviously
correct" :)

workqueue: Fixes for v7.0-rc3
- Improve workqueue stall diagnostics: dump all busy workers (not just
running ones), show wall-clock duration of in-flight work items, and
add a sample module for reproducing stalls.
- Fix POOL_BH vs WQ_BH flag namespace mismatch in pr_cont_worker_id().
- Rename pool->watchdog_ts to pool->last_progress_ts and related

perf tools fixes for v7.0:
- Fix stale build ID in module MMAP2 records in events synthesized for
pre-existing processes.
- Fix rust cross compilation.
- hashmap__new() error pointer return handling fixes.
- Fix off-by-one bug in outside of functions check on the disasm code.
- Update header copies of kernel headers, including prctl.h, mount.h, fs.h,
irq_vectors.h, perf_event.h, gfp_types.h, kvm.h, cpufeatures.h msr-index.h,
also the syscall tables files that introduced the 'rseq_slice_yield' syscall.
- Finish removal of ETM_OPT_* on the ARM coresight support, needed to sync
the coresight-pmu.h header with the kernel sources.
- Make in-target rule robust against too long argument error.
