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.

This is for use with persistent memory to ensure that stores for which
modifications are written to persistent storage reached a platform
durability domain.
For example, after a non-temporal write to pmem region, we use pmem_wmb()
to ensure that stores have reached a platform durability domain. This ensures
that stores have updated persistent storage before any data access or
data transfer caused by subsequent instructions is initiated. This is
in addition to the ordering done by wmb().
For load from persistent memory, existing read memory barriers are sufficient
to ensure read ordering.

Invocation
----------
The syscall is made with the sc instruction, and returns with execution
continuing at the instruction following the sc instruction.

scv 0 instruction is an alternative that may provide better performance,

.. [1] Some syscalls (typically low-level management functions) may have
different calling sequences (e.g., rt_sigreturn).
Parameters and return value
---------------------------
Parameters
----------
The system call number is specified in r0.
There is a maximum of 6 integer parameters to a syscall, passed in r3-r8.
Both a return value and a return error code are returned. cr0.SO is the return
error code, and r3 is the return value or error code. When cr0.SO is clear,
the syscall succeeded and r3 is the return value. When cr0.SO is set, the
syscall failed and r3 is the error code that generally corresponds to errno.
Return value
------------
- For the sc instruction, both a value and an error condition are returned.
cr0.SO is the error condition, and r3 is the return value. When cr0.SO is
clear, the syscall succeeded and r3 is the return value. When cr0.SO is set,
the syscall failed and r3 is the error value (that normally corresponds to
errno).
- For the scv 0 instruction, the return value indicates failure if it is
-4095..-1 (i.e., it is >= -MAX_ERRNO (-4095) as an unsigned comparison),
in which case the error value is the negated return value.
