  s390/cpumf: Adjust registration of s390 PMU device drivers (2019-11-20 17:16:01 +0100)

----------------------------------------------------------------
s390 updates for the 5.5 merge window

- 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.
