Linus Torvalds 1ec6d09789 s390 updates for 6.12 merge window
- 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
