Commit 3ae86d2d ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock LED") uses the WMI event-id for the fn-lock event on some Legion 5 laptops to manually toggle the fn-lock LED because the EC does not do it itself. However, the same WMI ID is also sent on some Yoga laptops. Here, setting the fn-lock state is not valid behavior, and causes the EC to spam interrupts until the laptop is rebooted. Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to manually set the LED on models on this list.

Fix the dodgy maths in netfs_rreq_unlock_folios(). start_page could be inside the folio, in which case the calculation of pgpos will be come up with a negative number (though for the moment rreq->start is rounded down earlier and folios would have to get merged whilst locked) Alter how this works to just frame the tracking in terms of absolute file positions, rather than offsets from the start of the I/O request. This simplifies the maths and makes it easier to follow. Fix the issue by using folio_pos() and folio_size() to calculate the end position of the page.

netfslib has a number of places in which it performs iteration of an xarray whilst being under the RCU read lock. It *should* call xas_retry() as the first thing inside of the loop and do "continue" if it returns true in case the xarray walker passed out a special value indicating that the walk needs to be redone from the root[*]. Fix this by adding the missing retry checks. [*] I wonder if this should be done inside xas_find(), xas_next_node() and suchlike, but I'm told that's not an simple change to effect. This can cause an oops like that below. Note the faulting address - this is an internal value (|0x2) returned from xarray. BUG: kernel NULL pointer dereference, address: 0000000000000402 ...

Add device nodes to enable support for battery and charger status, the ACPI platform profile, as well as internal and type-cover HID devices (including sensors, touchpad, keyboard, and other miscellaneous devices) on the Surface Pro 9. This does not include support for a tablet-mode switch yet, as that is now handled via the POS subsystem (unlike the Surface Pro 8, where it is handled via the KIP subsystem) and therefore needs further changes. While we're at it, also add the missing comment for the Surface Pro 8.

Currently, we check any received packet whether we have already seen it previously, regardless of the packet type (sequenced / unsequenced). We do this by checking the sequence number. This assumes that sequence numbers are valid for both sequenced and unsequenced packets. However, this assumption appears to be incorrect. On some devices, the sequence number field of unsequenced packets (in particular HID input events on the Surface Pro 9) is always zero. As a result, the current retransmission check kicks in and discards all but the first unsequenced packet, breaking (among other things) keyboard and touchpad input. Note that we have, so far, only seen packets being retransmitted in sequenced communication. In particular, this happens when there is an ACK timeout, causing the EC (or us) to re-send the packet waiting for an ACK. Arguably, retransmission / duplication of unsequenced packets should not be an issue as there is no logical condition (such as an ACK timeout) to determine when a packet should be sent again. Therefore, remove the retransmission check for unsequenced packets entirely to resolve the issue.

The current logic in the Intel PMC driver will forcefully attach it when detecting any CPU on the intel_pmc_core_platform_ids array, even if the matching ACPI device is not present. There's no checking in pmc_core_probe() to assert that the PMC device is present, and hence on virtualized environments the PMC device probes successfully, even if the underlying registers are not present. Before commit 21ae4357 ("platform/x86: intel_pmc_core: Substitute PCI with CPUID enumeration") the driver would check for the presence of a specific PCI device, and that prevented the driver from attaching when running virtualized. Fix by only forcefully attaching the PMC device when not running virtualized. Note that virtualized platforms can still get the device to load if the appropriate ACPI device is present on the tables provided to the VM. Make an exception for the Xen initial domain, which does have full hardware access, and hence can attach to the PMC if present.

Takashi Iwai authored
The latest fix for the non-contiguous memalloc helper changed the allocation method for a non-IOMMU system to use only the fallback allocator. This should have worked, but it caused a problem sometimes when too many non-contiguous pages are allocated that can't be treated by HD-audio controller. As a quirk workaround, go back to the original strategy: use dma_alloc_noncontiguous() at first, and apply the fallback only when it fails, but only for non-IOMMU case. We'll need a better fix in the fallback code as well, but this workaround should paper over most cases.

While the ATA specification states that a device should return command aborted for all commands queued after the device has entered error state, since ATA only keeps the sense data for the latest command (in non-NCQ case), we really don't want to send block layer commands to the device after it has entered error state. (Only ATA EH commands should be sent, to read the sense data etc.) Currently, scsi_queue_rq() will check if scsi_host_in_recovery() (state is SHOST_RECOVERY), and if so, it will _not_ issue a command via: scsi_dispatch_cmd() -> host->hostt->queuecommand() (ata_scsi_queuecmd()) -> __ata_scsi_queuecmd() -> ata_scsi_translate() -> ata_qc_issue() Before commit e494f6a7 ("[SCSI] improved eh timeout handler"), when receiving a TFES error IRQ, the call chain looked like this: ahci_error_intr() -> ata_port_abort() -> ata_do_link_abort() -> ata_qc_complete() -> ata_qc_schedule_eh() -> blk_abort_request() -> blk_rq_timed_out() -> q->rq_timed_out_fn() (scsi_times_out()) -> scsi_eh_scmd_add() -> scsi_host_set_state(shost, SHOST_RECOVERY) Which meant that as soon as an error IRQ was serviced, SHOST_RECOVERY would be set. However, after commit e494f6a7 ("[SCSI] improved eh timeout handler"), scsi_times_out() will instead call scsi_abort_command() which will queue delayed work, and the worker function scmd_eh_abort_handler() will call scsi_eh_scmd_add(), which calls scsi_host_set_state(shost, SHOST_RECOVERY). So now, after the TFES error IRQ has been serviced, we need to wait for the SCSI workqueue to run its work before SHOST_RECOVERY gets set. It is worth noting that, even before commit e494f6a7 ("[SCSI] improved eh timeout handler"), we could receive an error IRQ from the time when scsi_queue_rq() checks scsi_host_in_recovery(), to the time when ata_scsi_queuecmd() is actually called. In order to handle both the delayed setting of SHOST_RECOVERY and the window where we can receive an error IRQ, add a check against ATA_PFLAG_EH_PENDING (which gets set when servicing the error IRQ), inside ata_scsi_queuecmd() itself, while holding the ap->lock. (Since the ap->lock is held while servicing IRQs.)

Pull kvm "This is a pretty large diffstat for this time of the release. The main culprit is a reorganization of the AMD assembly trampoline, allowing percpu variables to be accessed early. This is needed for the return stack depth tracking retbleed mitigation that will be in 6.2, but it also makes it possible to tighten the IBRS restore on vmexit. The latter change is a long tail of the spectrev2/retbleed patches (the corresponding Intel change was simpler and went in already last June), which is why I am including it right now instead of sharing a topic branch with tip. Being assembly and being rich in comments makes the line count balloon a bit, but I am pretty confident in the change (famous last words) because the reorganization actually makes everything simpler and more understandable than before. It has also had external review and has been tested on the aforementioned 6.2 changes, which explode quite brutally without the fix. Apart from this, things are pretty normal. s390: - PCI fix - PV clock fix x86: - Fix clash between PMU MSRs and other MSRs - Prepare SVM assembly trampoline for 6.2 retbleed mitigation and for... - ... tightening IBRS restore on vmexit, moving it before the first RET or indirect branch - Fix log level for VMSA dump - Block all page faults during kvm_zap_gfn_range() Tools: - kvm_stat: fix incorrect detection of debugfs - kvm_stat: update vmexit definitions" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: x86/mmu: Block all page faults during kvm_zap_gfn_range() KVM: x86/pmu: Limit the maximum number of supported AMD GP counters KVM: x86/pmu: Limit the maximum number of supported Intel GP counters KVM: x86/pmu: Do not speculatively query Intel GP PMCs that don't exist yet KVM: SVM: Only dump VMSA to klog at KERN_DEBUG level tools/kvm_stat: update exit reasons for vmx/svm/aarch64/userspace tools/kvm_stat: fix incorrect detection of debugfs x86, KVM: remove unnecessary argument to x86_virt_spec_ctrl and callers KVM: SVM: move MSR_IA32_SPEC_CTRL save/restore to assembly KVM: SVM: restore host save area from assembly KVM: SVM: move guest vmsave/vmload back to assembly KVM: SVM: do not allocate struct svm_cpu_data dynamically KVM: SVM: remove dead field from struct svm_cpu_data KVM: SVM: remove unused field from struct vcpu_svm KVM: SVM: retrieve VMCB from assembly KVM: SVM: adjust register allocation for __svm_vcpu_run() KVM: SVM: replace regs argument of __svm_vcpu_run() with vcpu_svm KVM: x86: use a separate asm-offsets.c file KVM: s390: pci: Fix allocation size of aift kzdev elements KVM: s390: pv: don't allow userspace to set the clock under PV
