2025-12-19Bluetooth: btusb: revert use of devm_kzalloc in btusbRaphael Pinsonneault-Thibeault
This reverts commit 98921dbd00c4e ("Bluetooth: Use devm_kzalloc in btusb.c file"). In btusb_probe(), we use devm_kzalloc() to allocate the btusb data. This ties the lifetime of all the btusb data to the binding of a driver to one interface, INTF. In a driver that binds to other interfaces, ISOC and DIAG, this is an accident waiting to happen. The issue is revealed in btusb_disconnect(), where calling usb_driver_release_interface(&btusb_driver, data->intf) will have devm free the data that is also being used by the other interfaces of the driver that may not be released yet. To fix this, revert the use of devm and go back to freeing memory explicitly.

2025-12-19parisc: Set valid bit in high byte of 64‑bit physical addressLeon Romanovsky
On 32‑bit systems, phys_addr_t is defined as u32. However, parisc expects physical addresses to be 64‑bit values so it can store a validity bit in the upper byte. Resolve this mismatch by casting the physical address to unsigned long, ensuring it is treated as a 64‑bit value where required. This fixes the failure to start block device drivers on the C3700 platform, as reported by Guenter. QEMU command line to reproduce the issue (with Debian SID as rootfs): qemu-system-hppa -machine C3700 \ -kernel arch/parisc/boot/bzImage \ -append "console=ttyS0 \ root=/dev/sda rw rootwait panic=-1" \ -nographic \ -device lsi53c895a \ -drive file=rootfs-hppa.img,if=none,format=raw,id=hd0 \ -device scsi-hd,drive=hd0 Fixes: 96ddf2ef58ec ("parisc: Convert DMA map_page to map_phys interface") Reported-by: Guenter Roeck <linux@roeck-us.net> Closes: https://lore.kernel.org/all/b184f1bf-96dc-4546-8512-9cba5ecb58f7@roeck-us.net/ Signed-off-by: Leon Romanovsky <leonro@nvidia.com> Tested-by: Guenter Roeck <linux@roeck-us.net> [mszyprow: dropped the lpa() macro removal] Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Link: https://lore.kernel.org/r/20251218-fix-parisc-conversion-v1-1-4a04d26b0168@nvidia.com

2025-12-19riscv: signal: abstract header saving for setup_sigcontextAndy Chiu
The function save_v_state() served two purposes. First, it saved extension context into the signal stack. Then, it constructed the extension header if there was no fault. The second part is independent of the extension itself. As a result, we can pull that part out, so future extensions may reuse it. This patch adds arch_ext_list and makes setup_sigcontext() go through all possible extensions' save() callback. The callback returns a positive value indicating the size of the successfully saved extension. Then the kernel proceeds to construct the header for that extension. The kernel skips an extension if it does not exist, or if the saving fails for some reasons. The error code is propagated out on the later case. This patch does not introduce any functional changes.

In qm_get_complete_eqe_num(), the function entry has already checked whether the interrupt is valid, so the interrupt event can be processed directly. Currently, the interrupt valid bit is being checked again redundantly, and no interrupt processing is performed. Therefore, the loop condition should be modified to directly process the interrupt event, and use do while instead of the current while loop, because the condition is always satisfied on the first iteration.

This causes a warning when perf registers a synthetic event and passes a NULL pointer to the tracepoint register function. Ideally synthetic events should be updated to work with perf, but as that's a feature and not a bug fix, simply now return -ENODEV when perf tries to register an event that has a NULL pointer for its function. This no longer causes a kernel warning and simply causes the perf code to fail with an error message. - Fix 32bit overflow in option flag test The option's flags changed from 32 bits in size to 64 bits in size.

Under certain conditions (more prevalent after a suspend/resume cycle), the touchscreen controller can send the "boot complete" interrupt before it actually finished booting. In those cases, attempting to read touch data resuls in a stream of "not ready" messages being read and interpreted as a touch report. Check that the response is in fact a touch report and discard it otherwise.

2025-12-18ASoC: ops: fix snd_soc_get_volsw for sx controlsStefan Binding
SX controls are currently broken, since the clamp introduced in commit a0ce874cfaaa ("ASoC: ops: improve snd_soc_get_volsw") does not handle SX controls, for example where the min value in the clamp is greater than the max value in the clamp. Add clamp parameter to prevent clamping in SX controls. The nature of SX controls mean that it wraps around 0, with a variable number of bits, therefore clamping the value becomes complicated and prone to error. Fixes 35 kunit tests for soc_ops_test_access.

KVM fixes for 6.19-rc1 - Add a missing "break" to fix param parsing in the rseq selftest. - Apply runtime updates to the _current_ CPUID when userspace is setting CPUID, e.g. as part of vCPU hotplug, to fix a false positive and to avoid dropping the pending update. - Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslot, as it's not supported by KVM and leads to a use-after-free due to KVM failing to unbind the memslot from the previously-associated guest_memfd instance. - Harden against similar KVM_MEM_GUEST_MEMFD goofs, and prepare for supporting flags-only changes on KVM_MEM_GUEST_MEMFD memlslots, e.g. for dirty logging. - Set exit_code[63:32] to -1 (all 0xffs) when synthesizing a nested SVM_EXIT_ERR (a.k.a. VMEXIT_INVALID) #VMEXIT, as VMEXIT_INVALID is defined as -1ull (a 64-bit value). - Update SVI when activating APICv to fix a bug where a post-activation EOI for an in-service IRQ would effective be lost due to SVI being stale. - Immediately refresh APICv controls (if necessary) on a nested VM-Exit instead of deferring the update via KVM_REQ_APICV_UPDATE, as the request is effectively ignored because KVM thinks the vCPU already has the correct APICv settings.

2025-12-18drm/xe: Drop preempt-fences when destroying imported dma-bufs.Thomas Hellström
When imported dma-bufs are destroyed, TTM is not fully individualizing the dma-resv, but it *is* copying the fences that need to be waited for before declaring idle. So in the case where the bo->resv != bo->_resv we can still drop the preempt-fences, but make sure we do that on bo->_resv which contains the fence-pointer copy. In the case where the copying fails, bo->_resv will typically not contain any fences pointers at all, so there will be nothing to drop. In that case, TTM would have ensured all fences that would have been copied are signaled, including any remaining preempt fences.

2025-12-18drm/xe: Adjust long-running workload timeslices to reasonable valuesMatthew Brost
A 10ms timeslice for long-running workloads is far too long and causes significant jitter in benchmarks when the system is shared. Adjust the value to 5ms for preempt-fencing VMs, as the resume step there is quite costly as memory is moved around, and set it to zero for pagefault VMs, since switching back to pagefault mode after dma-fence mode is relatively fast. Also change min_run_period_ms to 'unsiged int' type rather than 's64' as only positive values make sense.
