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 's390-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Vasily Gorbik:
- Optimize ftrace and kprobes code patching and avoid stop machine for kprobes if sequential instruction fetching facility is available
- Add hiperdispatch feature to dynamically adjust CPU capacity in vertical polarization to improve scheduling efficiency and overall performance. Also add infrastructure for handling warning track interrupts (WTI), allowing for graceful CPU preemption
- Rework crypto code pkey module and split it into separate, independent modules for sysfs, PCKMO, CCA, and EP11, allowing modules to load only when the relevant hardware is available
- Add hardware acceleration for HMAC modes and the full AES-XTS cipher, utilizing message-security assist extensions (MSA) 10 and 11. It introduces new shash implementations for HMAC-SHA224/256/384/512 and registers the hardware-accelerated AES-XTS cipher as the preferred option. Also add clear key token support
- Add MSA 10 and 11 processor activity instrumentation counters to perf and update PAI Extension 1 NNPA counters
- Cleanup cpu sampling facility code and rework debug/WARN_ON_ONCE statements
- Add support for SHA3 performance enhancements introduced with MSA 12
- Add support for the query authentication information feature of MSA 13 and introduce the KDSA CPACF instruction. Provide query and query authentication information in sysfs, enabling tools like cpacfinfo to present this data in a human-readable form
- Update kernel disassembler instructions
- Always enable EXPOLINE_EXTERN if supported by the compiler to ensure kpatch compatibility
- Add missing warning handling and relocated lowcore support to the early program check handler
- Optimize ftrace_return_address() and avoid calling unwinder
- Make modules use kernel ftrace trampolines
- Strip relocs from the final vmlinux ELF file to make it roughly 2 times smaller
- Dump register contents and call trace for early crashes to the console
- Generate ptdump address marker array dynamically
- Fix rcu_sched stalls that might occur when adding or removing large amounts of pages at once to or from the CMM balloon
- Fix deadlock caused by recursive lock of the AP bus scan mutex
- Unify sync and async register save areas in entry code
- Cleanup debug prints in crypto code
- Various cleanup and sanitizing patches for the decompressor
- Various small ftrace cleanups

s390/pkey: Add slowpath function to CCA and EP11 handler
For some keys there exists an alternative but usually slower path to convert the key material into a protected key. This patch introduces a new handler function slowpath_key_to_protkey() which provides this alternate path for the CCA and EP11 handler code. With that even the knowledge about how and when this can be used within the pkey API code can be removed. So now the pkey API just tries the primary way and if that fails simple tries the alternative way.

s390/pkey: Introduce pkey base with handler registry and handler modules
Introduce pkey base kernel code with a simple pkey handler registry. Regroup the pkey code into these kernel modules: - pkey is the pkey api supporting the ioctls, sysfs and in-kernel api. Also the pkey base code which offers the handler registry and handler wrapping invocation functions is integrated there. This module is automatically loaded in via CPU feature if the MSA feature is available. - pkey-cca is the CCA related handler code kernel module a offering CCA specific implementation for pkey. This module is loaded in via MODULE_DEVICE_TABLE when a CEX[4-8] card becomes available. - pkey-ep11 is the EP11 related handler code kernel module offering an EP11 specific implementation for pkey. This module is loaded in via MODULE_DEVICE_TABLE when a CEX[4-8] card becomes available. - pkey-pckmo is the PCKMO related handler code kernel module. This module is loaded in via CPU feature if the MSA feature is available, but on init a check for availability of the pckmo instruction is performed.
The handler modules register via a pkey_handler struct at the pkey base code and the pkey customer (that is currently the pkey api code fetches a handler via pkey handler registry functions and calls the unified handler functions via the pkey base handler functions.
As a result the pkey-cca, pkey-ep11 and pkey-pckmo modules get independent from each other and it becomes possible to write new handlers which offer another kind of implementation without implicit dependencies to other handler implementations and/or kernel device drivers.
For each of these 4 kernel modules there is an individual Kconfig entry: CONFIG_PKEY for the base and api, CONFIG_PKEY_CCA for the PKEY CCA support handler, CONFIG_PKEY_EP11 for the EP11 support handler and CONFIG_PKEY_PCKMO for the pckmo support. The both CEX related handler modules (PKEY CCA and PKEY EP11) have a dependency to the zcrypt api of the zcrypt device driver.

As a preparation step for introducing a common function API between the pkey API module and the handlers (that is the cca, ep11 and pckmo code) this patch unifies the functions signatures exposed by the handlers and reworks all the invocation code of these functions.

s390/pkey: Rework and split PKEY kernel module code
This is a huge rework of all the pkey kernel module code. The goal is to split the code into individual parts with a dedicated calling interface: - move all the sysfs related code into pkey_sysfs.c - all the CCA related code goes to pkey_cca.c - the EP11 stuff has been moved to pkey_ep11.c - the PCKMO related code is now in pkey_pckmo.c
The CCA, EP11 and PCKMO code may be seen as "handlers" with a similar calling interface. The new header file pkey_base.h declares this calling interface. The remaining code in pkey_api.c handles the ioctl, the pkey module things and the "handler" independent code on top of the calling interface invoking the handlers.
This regrouping of the code will be the base for a real pkey kernel module split into a pkey base module which acts as a dispatcher and handler modules providing their service.
