2025-06-10platform/x86/amd: pmf: Use device managed allocationsMario Limonciello
If setting up smart PC fails for any reason then this can lead to a double free when unloading amd-pmf. This is because dev->buf was freed but never set to NULL and is again freed in amd_pmf_remove(). To avoid subtle allocation bugs in failures leading to a double free change all allocations into device managed allocations.

2025-06-10ALSA: sb: Force to disable DMAs once when DMA mode is changedTakashi Iwai
When the DMA mode is changed on the (still real!) SB AWE32 after playing a stream and closing, the previous DMA setup was still silently kept, and it can confuse the hardware, resulting in the unexpected noises. As a workaround, enforce the disablement of DMA setups when the DMA setup is changed by the kcontrol. https://bugzilla.kernel.org/show_bug.cgi?id=218185 Link: https://patch.msgid.link/20250610064322.26787-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

When a host is configured with a few LUNs and I/O is running, injecting FC faults repeatedly leads to path recovery problems. The LUNs have 4 paths each and 3 of them come back active after say an FC fault which makes 2 of the paths go down, instead of all 4. This happens after several iterations of continuous FC faults. Reason here is that we're returning an I/O error whenever we're encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC ACCESS STATE TRANSITION) instead of retrying.

2025-06-09scsi: s390: zfcp: Ensure synchronous unit_addPeter Oberparleiter
Improve the usability of the unit_add sysfs attribute by ensuring that the associated FCP LUN scan processing is completed synchronously. This enables configuration tooling to consistently determine the end of the scan process to allow for serialization of follow-on actions. While the scan process associated with unit_add typically completes synchronously, it is deferred to an asynchronous background process if unit_add is used before initial remote port scanning has completed. This occurs when unit_add is used immediately after setting the associated FCP device online. To ensure synchronous unit_add processing, wait for remote port scanning to complete before initiating the FCP LUN scan.

Correct the error handling goto labels used when host lookup fails in various flashnode-related event handlers: - iscsi_new_flashnode() - iscsi_del_flashnode() - iscsi_login_flashnode() - iscsi_logout_flashnode() - iscsi_logout_flashnode_sid() scsi_host_put() is not required when shost is NULL, so jumping to the correct label avoids unnecessary operations. These functions previously jumped to the wrong goto label (put_host), which did not match the intended cleanup logic. Use the correct exit labels (exit_new_fnode, exit_del_fnode, etc.) to ensure proper error handling. Also remove the unused put_host label under iscsi_new_flashnode() as it is no longer needed.

2025-06-09drm/msm: Temporarily disable stall-on-fault after a page faultConnor Abbott
When things go wrong, the GPU is capable of quickly generating millions of faulting translation requests per second. When that happens, in the stall-on-fault model each access will stall until it wins the race to signal the fault and then the RESUME register is written. This slows processing page faults to a crawl as the GPU can generate faults much faster than the CPU can acknowledge them. It also means that all available resources in the SMMU are saturated waiting for the stalled transactions, so that other transactions such as transactions generated by the GMU, which shares translation resources with the GPU, cannot proceed. This causes a GMU watchdog timeout, which leads to a failed reset because GX cannot collapse when there is a transaction pending and a permanently hung GPU. On older platforms with qcom,smmu-v2, it seems that when one transaction is stalled subsequent faulting transactions are terminated, which avoids this problem, but the MMU-500 follows the spec here. To work around these problems, disable stall-on-fault as soon as we get a page fault until a cooldown period after pagefaults stop. This allows the GMU some guaranteed time to continue working. We only use stall-on-fault to halt the GPU while we collect a devcoredump and we always terminate the transaction afterward, so it's fine to miss some subsequent page faults. We also keep it disabled so long as the current devcoredump hasn't been deleted, because in that case we likely won't capture another one if there's a fault. After this commit HFI messages still occasionally time out, because the crashdump handler doesn't run fast enough to let the GMU resume, but the driver seems to recover from it. This will probably go away after the HFI timeout is increased.

2025-06-09SPI: omap2-mcspi: Fix SPI CS behaviour aroundMark Brown
Merge series from Félix Piédallu <felix.piedallu@non.se.com>: These patches fix the behaviour of the SPI Chip Select of the OMAP2 MCSPI driver used on TI SoCs. The omap2-mcspi driver supports the use of multi mode (multichannel in TI documentation). In this mode, the CS is asserted and deasserted by the hardware. The multi mode is disabled for messages when cs_change=0 for all transfers (e.g when CS is kept asserted between transfers of a same message). The multi mode also needs to be disabled for messages when cs_change=1 on the last transfer (e.g when CS is kept asserted after the WHOLE message), and the message right after. Currently, that is not the case and it CS is deasserted by hardware when it shouldn't. This breaks peripheral drivers that send multiple messages with the CS asserted in between. Patch 1 ensures that multi mode is disabled when cs_change=1 on the last transfer of the message. Patch 2 ensures that multi mode is disable on a message following one with cs_change=1 on the last transfer. This is the case for the TPM TIS SPI driver that uses this logic for flow control purposes. Tested on an AM6442 platform with a TPM ST33HTPH2X32AHE4.

All the BCMBCA SoCs share a set of peripherals at 0xff800000, albeit at slightly varying memory locations on the bus and with varying IRQ assignments. Add the first and second watchdog, GPIO, RNG, LED, DMA and second PL011 UART blocks for the BCM6855 based on the vendor files 6855_map_part.h and 6855_intr.h from the "bcmopen-consumer" code drop.

All the BCMBCA SoCs share a set of peripherals at 0xff800000, albeit at slightly varying memory locations on the bus and with varying IRQ assignments. Add the watchdog, GPIO blocks, RNG, LED, second UART and DMA blocks for the BCM63158 based on the vendor files 63158_map_part.h and 63158_intr.h from the "bcmopen-consumer" code drop. The DTSI file has clearly been authored for the B0 revision of the SoC: there is an earlier A0 version, but this has the UARTs in the legacy PERF memory space, while the B0 has opened a new peripheral window at 0xff812000 for the three UARTs. It also has a designated AHB peripheral area at 0xff810000 where the DMA resides, the peripheral range window fits these two peripheral groups. This SoC has up to 256 possible GPIOs due to having 8 registers with 32 GPIOs in each available.

2025-06-09ARC: Replace __ASSEMBLY__ with __ASSEMBLER__ in the non-uapi headersThomas Huth
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize on the __ASSEMBLER__ macro that is provided by the compilers now. This is a completely mechanical patch (done with a simple "sed -i" statement).
