- Adjust PMU device drivers registration to avoid WARN_ON and few other
perf improvements.
- Enhance tracing in vfio-ccw.
- Few stack unwinder fixes and improvements, convert get_wchan custom
stack unwinding to generic api usage.
- Fixes for mm helpers issues uncovered with tests validating architecture
page table helpers.
- Fix noexec bit handling when hardware doesn't support it.
- Fix memleak and unsigned value compared with zero bugs in crypto
code. Minor code simplification.
- Fix crash during kdump with kasan enabled kernel.
- Switch bug and alternatives from asm to asm_inline to improve inlining
decisions.
- Use 'depends on cc-option' for MARCH and TUNE options in Kconfig,
add z13s and z14 ZR1 to TUNE descriptions.
- Minor head64.S simplification.
- Fix physical to logical CPU map for SMT.
- Several cleanups in qdio code.
- Other minor cleanups and fixes all over the code.
