  selftests/powerpc: Fix pkey syscall redefinitions (2020-08-05 10:14:03 +1000)


- ------------------------------------------------------------------
powerpc updates for 5.9

 - Add support for (optionally) using queued spinlocks & rwlocks.

 - Support for a new faster system call ABI using the scv instruction on Power9
   or later.

 - Drop support for the PROT_SAO mmap/mprotect flag as it will be unsupported on
   Power10 and future processors, leaving us with no way to implement the
   functionality it requests. This risks breaking userspace, though we believe
   it is unused in practice.

 - A bug fix for, and then the removal of, our custom stack expansion checking.
   We now allow stack expansion up to the rlimit, like other architectures.

 - Remove the remnants of our (previously disabled) topology update code, which
   tried to react to NUMA layout changes on virtualised systems, but was prone
   to crashes and other problems.

 - Add PMU support for Power10 CPUs.

 - A change to our signal trampoline so that we don't unbalance the link stack
   (branch return predictor) in the signal delivery path.

 - Lots of other cleanups, refactorings, smaller features and so on as usual.
