Pull power management fixes from Rafael Wysocki:
 "These fix two issues in the Operating Performance Points (OPP)
  framework, one cpufreq driver issue, one problem related to the tasks
  freezer and a few build-related issues in the cpupower utility.

  Specifics:

   - Fix tasks freezer deadlock in de_thread() that occurs if one of its
     sub-threads has been frozen already (Chanho Min).

   - Avoid registering a platform device by the ti-cpufreq driver on
     platforms that cannot use it (Dave Gerlach).

   - Fix a mistake in the ti-opp-supply operating performance points
     (OPP) driver that caused an incorrect reference voltage to be used
     and make it adjust the minimum voltage dynamically to avoid hangs
     or crashes in some cases (Keerthy).

   - Fix issues related to compiler flags in the cpupower utility and
     correct a linking problem in it by renaming a file with a duplicate
     name (Jiri Olsa, Konstantin Khlebnikov)"

Pull libnvdimm fixes from Dan Williams:
 "A small batch of fixes for v4.20-rc3.

  The overflow continuation fix addresses something that has been broken
  for several releases. Arguably it could wait even longer, but it's a
  one line fix and this finishes the last of the known address range
  scrub bug reports. The revert addresses a lockdep regression. The unit
  tests are not critical to fix, but no reason to hold this fix back.

  Summary:

   - Address Range Scrub overflow continuation handling has been broken
     since it was initially merged. It was only recently that error
     injection and platform-BIOS support enabled this corner case to be
     exercised.

   - The recent attempt to provide more isolation for the kernel Address
     Range Scrub state machine from userapace initiated sessions
     triggers a lockdep report. Revert and try again at the next merge
     window.

   - Fix a kasan reported buffer overflow in libnvdimm unit test
     infrastrucutre (nfit_test)"

Pull powerpc fixes from Michael Ellerman:
 "Two weeks worth of fixes since rc1.

   - I broke 16-byte alignment of the stack when we moved PPR into
     pt_regs. Despite being required by the ABI this broke almost
     nothing, we eventually hit it in code where GCC does arithmetic on
     the stack pointer assuming the bottom 4 bits are clear. Fix it by
     padding the in-kernel pt_regs by 8 bytes.

   - A couple of commits fixing minor bugs in the recent SLB rewrite.

   - A build fix related to tracepoints in KVM in some configurations.

   - Our old "IO workarounds" code written for Cell couldn't coexist in
     a kernel that runs on Power9 with the Radix MMU, fix that.

   - Remove the NPU DMA ops, these just printed a warning and should
     never have been called.

   - Suppress an overly chatty message triggered by CPU hotplug in some
     configs.

   - Two small selftest fixes.

Currently the selftest wild_bctr can fail to build when an old gcc is
used, notably on gcc using a binutils version <= 2.27, because the
assembler does not support the integer suffix UL.

This patch adjusts the wild_bctr test so the REG_POISON value is still
treated as an unsigned long for the shifts on compilation but the UL
suffix is absent on the stringification, so the inline asm code
generated has no UL suffixes.

The selftest I recently added to test branching to an out-of-bounds
NIP doesn't work on 64-bit big endian. It does fail but not in the
right way. That is it SEGVs trying to load from the opd at BAD_NIP,
but it never gets as far as branching to BAD_NIP.

To fix it we need to create an opd which is reachable but which holds
the bad address.
