[tip: timers/urgent] clocksource/i8253: Use raw_spinlock_irqsave() in clockevent_i8253_disable()

If some of the old i8253 hardware is actually used then lockdep will notice that i8253_lock is used in hard interrupt context. This causes lockdep to complain because it observed the lock being acquired with interrupts enabled and in hard interrupt context. Make clockevent_i8253_disable() acquire the lock with raw_spinlock_irqsave() to cure this.

[PATCH 2/2] xhci: dbc: Avoid event polling busyloop if pending rx transfers are inactive.

by Mathias Nyman

Event polling delay is set to 0 if there are any pending requests in either rx or tx requests lists. Checking for pending requests does not work well for "IN" transfers as the tty driver always queues requests to the list and TRBs to the ring, preparing to receive data from the host. This causes unnecessary busylooping and cpu hogging. Only set the event polling delay to 0 if there are pending tx "write" transfers, or if it was less than 10ms since last active data transfer in any direction.

[PATCH v2 rc] iommu: Skip PASID validation for devices without PASID capability

by Tushar Dave

Generally PASID support requires ACS settings that usually create single device groups, but there are some niche cases where we can get multi-device groups and still have working PASID support. The primary issue is that PCI switches are not required to treat PASID tagged TLPs specially so appropriate ACS settings are required to route all TLPs to the host bridge if PASID is going to work properly. pci_enable_pasid() does check that each device that will use PASID has the proper ACS settings to achieve this routing. However, no-PASID devices can be combined with PASID capable devices within the same topology using non-uniform ACS settings. In this case the no-PASID devices may not have strict route to host ACS flags and end up being grouped with the PASID devices. This configuration fails to allow use of the PASID within the iommu core code which wrongly checks if the no-PASID device supports PASID. Fix this by ignoring no-PASID devices during the PASID validation. They will never issue a PASID TLP anyhow so they can be ignored.

[PATCH] xfs: fix diff_two_keys calculation for cnt btree

by Fedor Pchelkin

Currently the difference is computed on 32-bit unsigned values although eventually it is stored in a variable of int64_t type. This gives awkward results, e.g. when the diff _should_ be negative, it is represented as some large positive int64_t value. Perform the calculations directly in int64_t as all other diff_two_keys routines actually do. Found by Linux Verification Center (linuxtesting.org) with Svace static analysis tool.

[PATCH 0/7] accel/ivpu: Add context violation handling for 6.12

by Jacek Lawrynowicz

These patchset adds support for VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW message added in recent VPU firmware. Without it the driver will not be able to process any jobs after this message is received and would need to be reloaded. Most patches are as-is from upstream besides these two: - Fix locking order in ivpu_job_submit - Abort all jobs after command queue unregister Both these patches need to be rebased because of missing new CMDQ UAPI changes that should not be backported to stable.
