Linus Torvalds 8d6973327e powerpc updates for 4.21
Notable changes:
 
  - Mitigations for Spectre v2 on some Freescale (NXP) CPUs.
 
  - A large series adding support for pass-through of Nvidia V100 GPUs to guests
    on Power9.
 
  - Another large series to enable hardware assistance for TLB table walk on
    MPC8xx CPUs.
 
  - Some preparatory changes to our DMA code, to make way for further cleanups
    from Christoph.
 
  - Several fixes for our Transactional Memory handling discovered by fuzzing the
    signal return path.
 
  - Support for generating our system call table(s) from a text file like other
    architectures.
 
  - A fix to our page fault handler so that instead of generating a WARN_ON_ONCE,
    user accesses of kernel addresses instead print a ratelimited and
    appropriately scary warning.
 
  - A cosmetic change to make our unhandled page fault messages more similar to
    other arches and also more compact and informative.
 
  - Freescale updates from Scott:
    "Highlights include elimination of legacy clock bindings use from dts
     files, an 83xx watchdog handler, fixes to old dts interrupt errors, and
     some minor cleanup."
 
 And many clean-ups, reworks and minor fixes etc.
