#     
#     Pull powerpc fixes from Michael Ellerman:
#      "A bit of a big batch, partly because I didn't send any last week, and
#       also just because the BPF fixes happened to land this week.
#     
#       Summary:
#     
#        - Fix a regression hit by the IPR SCSI driver, introduced by the
#          recent addition of MSI domains on pseries.
#     
#        - A big series including 8 BPF fixes, some with potential security
#          impact and the rest various code generation issues.
#     
#        - Fix our program check assembler entry path, which was accidentally
#          jumping into a gas macro and generating strange stack frames, which
#          could confuse find_bug().
#     
#        - A couple of fixes, and related changes, to fix corner cases in our
#          machine check handling.
#     
#        - Fix our DMA IOMMU ops, which were not always returning the optimal
#          DMA mask, leading to at least one device falling back to 32-bit DMA
#          when it shouldn't.
#     
#        - A fix for KUAP handling on 32-bit Book3S.
#     
#        - Fix crashes seen when kdumping on some pseries systems.
#     
#       Thanks to Naveen N. Rao, Nicholas Piggin, Alexey Kardashevskiy, Cédric
#       Le Goater, Christophe Leroy, Mahesh Salgaonkar, Abdul Haleem,
#       Christoph Hellwig, Johan Almbladh, Stan Johnson"
