      Linus Torvalds authored 
      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.

  Thanks to: Alistair Popple, Gustavo Romero, Nicholas Piggin, Satheesh
  Rajendran, Scott Wood"

      Revert "ACPI/PCI: Pay attention to device-specific _PXM node values" · 0d76bcc9
      Bjorn Helgaas authored 
      This reverts commit bad7dcd9.

bad7dcd9 ("ACPI/PCI: Pay attention to device-specific _PXM node
values") caused boot failures (no console output at all) for Martin [1]
and Ingo [2] on AMD ThreadRipper systems.

Revert the commit until we figure out how to safely use these
device-specific _PXM values.
