Linus Torvalds b970afcfca powerpc updates for 5.2 
Highlights:
 
  - Support for Kernel Userspace Access/Execution Prevention (like
    SMAP/SMEP/PAN/PXN) on some 64-bit and 32-bit CPUs. This prevents the kernel
    from accidentally accessing userspace outside copy_to/from_user(), or
    ever executing userspace.
 
  - KASAN support on 32-bit.
 
  - Rework of where we map the kernel, vmalloc, etc. on 64-bit hash to use the
    same address ranges we use with the Radix MMU.
 
  - A rewrite into C of large parts of our idle handling code for 64-bit Book3S
    (ie. power8 & power9).
 
  - A fast path entry for syscalls on 32-bit CPUs, for a 12-17% speedup in the
    null_syscall benchmark.
 
  - On 64-bit bare metal we have support for recovering from errors with the time
    base (our clocksource), however if that fails currently we hang in __delay()
    and never crash. We now have support for detecting that case and short
    circuiting __delay() so we at least panic() and reboot.
 
  - Add support for optionally enabling the DAWR on Power9, which had to be
    disabled by default due to a hardware erratum. This has the effect of
    enabling hardware breakpoints for GDB, the downside is a badly behaved
    program could crash the machine by pointing the DAWR at cache inhibited
    memory. This is opt-in obviously.
 
  - xmon, our crash handler, gets support for a read only mode where operations
    that could change memory or otherwise disturb the system are disabled.
 
 Plus many clean-ups, reworks and minor fixes etc.

Pull powerpc updates from Michael Ellerman:
 "Slightly delayed due to the issue with printk() calling
  probe_kernel_read() interacting with our new user access prevention
  stuff, but all fixed now.

  The only out-of-area changes are the addition of a cpuhp_state, small
  additions to Documentation and MAINTAINERS updates.

     SMAP/SMEP/PAN/PXN) on some 64-bit and 32-bit CPUs. This prevents
