Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 6.12, take #1
- Fix pKVM error path on init, making sure we do not change critical system registers as we're about to fail
- Make sure that the host's vector length is at capped by a value common to all CPUs
- Fix kvm_has_feat*() handling of "negative" features, as the current code is pretty broken
- Promote Joey to the status of official reviewer, while James steps down -- hopefully only temporarly

ASoC: Fixes for v6.12
A bunch of fixes here that came in during the merge window and the first week of release, plus some new quirks and device IDs. There's nothing major here, it's a bit bigger than it might've been due to there being no fixes sent during the merge window due to your vacation.

Merge tag 'sched_ext-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext support from Tejun Heo: "This implements a new scheduler class called ‘ext_sched_class’, or sched_ext, which allows scheduling policies to be implemented as BPF programs.
The goals of this are:
- Ease of experimentation and exploration: Enabling rapid iteration of new scheduling policies.
- Customization: Building application-specific schedulers which implement policies that are not applicable to general-purpose schedulers.
- Rapid scheduler deployments: Non-disruptive swap outs of scheduling policies in production environments"
See individual commits for more documentation, but also the cover letter for the latest series:

sched_ext: Add scx_simple and scx_example_qmap example schedulers
Add two simple example BPF schedulers - simple and qmap.
* simple: In terms of scheduling, it behaves identical to not having any operation implemented at all. The two operations it implements are only to improve visibility and exit handling. On certain homogeneous configurations, this actually can perform pretty well.
* qmap: A fixed five level priority scheduler to demonstrate queueing PIDs on BPF maps for scheduling. While not very practical, this is useful as a simple example and will be used to demonstrate different features.
v7: - Compat helpers stripped out in prepartion of upstreaming as the upstreamed patchset will be the baselinfe. Utility macros that can be used to implement compat features are kept.
- Explicitly disable map autoattach on struct_ops to avoid trying to attach twice while maintaining compatbility with older libbpf.
v6: - Common header files reorganized and cleaned up. Compat helpers are added to demonstrate how schedulers can maintain backward compatibility with older kernels while making use of newly added features.
- simple_select_cpu() added to keep track of the number of local dispatches. This is needed because the default ops.select_cpu() implementation is updated to dispatch directly and won't call ops.enqueue().
- Updated to reflect the sched_ext API changes. Switching all tasks is the default behavior now and scx_qmap supports partial switching when `-p` is specified.
- tools/sched_ext/Kconfig dropped. This will be included in the doc instead.
v5: - Improve Makefile. Build artifects are now collected into a separate dir which change be changed. Install and help targets are added and clean actually cleans everything.
- MEMBER_VPTR() improved to improve access to structs. ARRAY_ELEM_PTR() and RESIZEABLE_ARRAY() are added to support resizable arrays in .bss.
- Add scx_common.h which provides common utilities to user code such as SCX_BUG[_ON]() and RESIZE_ARRAY().
- Use SCX_BUG[_ON]() to simplify error handling.
v4: - Dropped _example prefix from scheduler names.
v3: - Rename scx_example_dummy to scx_example_simple and restructure a bit to ease later additions. Comment updates.
- Added declarations for BPF inline iterators. In the future, hopefully, these will be consolidated into a generic BPF header so that they don't need to be replicated here.
v2: - Updated with the generic BPF cpumask helpers.
