2025-09-01dm-pcache: remove ctrl_lock for pcache_cache_segmentDongsheng Yang
The smatch checker reports a “scheduler in atomic context” problem in the following call chain: miss_read_end_req() -> cache_seg_put() -> cache_seg_invalidate() -> cache_seg_gen_increase() -> mutex_lock(&cache_seg->ctrl_lock); In practice, this `mutex_lock` will not actually schedule, because it is only called when `cache_seg_put()` drops the last reference, which is single-threaded. That is also why the issue never shows up during real testing. However, the code is still buggy. The original purpose of `ctrl_lock` was to prevent read/write conflicts on the cache segment control information. Looking at the current usage, all control information accesses are single-threaded: reads only occur during the init phase, where no conflicts are possible, and writes happen once in the init phase (also single-threaded) and once when `cache_seg_put()` drops the last reference (again single-threaded). Therefore, this patch removes `ctrl_lock` entirely and adds comments in the appropriate places to document this logic.

2025-09-01x86/sev: Prevent SECURE_AVIC_CONTROL MSR interception for Secure AVIC guestsNeeraj Upadhyay
The SECURE_AVIC_CONTROL MSR holds the GPA of the guest APIC backing page and bitfields to control enablement of Secure AVIC and whether the guest allows NMIs to be injected by the hypervisor. This MSR is populated by the guest and can be read by the guest to get the GPA of the APIC backing page. The MSR can only be accessed in Secure AVIC mode. Any attempt to access it when not in Secure AVIC mode results in #GP. So, the hypervisor should not intercept it. A #VC exception will be generated otherwise. If this occurs and Secure AVIC is enabled, terminate the guest execution.

2025-09-01ALSA: usb-audio: Allow Focusrite devices to use low sampleratesTina Wuest
Commit 05f254a6369ac020fc0382a7cbd3ef64ad997c92 ("ALSA: usb-audio: Improve filtering of sample rates on Focusrite devices") changed the check for max_rate in a way which was overly restrictive, forcing devices to use very high samplerates if they support them, despite support existing for lower rates as well. This maintains the intended outcome (ensuring samplerates selected are supported) while allowing devices with higher maximum samplerates to be opened at all supported samplerates.

2025-09-01drm/imagination: Enable PowerVR driver for RISC-VMichal Wilczynski
Several RISC-V boards feature Imagination GPUs that are compatible with the PowerVR driver. An example is the IMG BXM-4-64 GPU on the Lichee Pi 4A board. This commit adjusts the driver's Kconfig dependencies to allow the PowerVR driver to be compiled on the RISC-V architecture. By enabling compilation on RISC-V, we expand support for these GPUs, providing graphics acceleration capabilities and enhancing hardware compatibility on RISC-V platforms. The RISC-V support is restricted to 64-bit systems (RISCV && 64BIT) as the driver currently has an implicit dependency on a 64-bit platform. Add a dependency on MMU to fix a build warning on RISC-V configurations without an MMU.
