Pull asm-generic updates from Arnd Bergmann:
 "The asm-generic changes for 5.3 consist of a cleanup series to remove
  ptrace.h from Christoph Hellwig, who explains:

    'asm-generic/ptrace.h is a little weird in that it doesn't actually
     implement any functionality, but it provided multiple layers of
     macros that just implement trivial inline functions. We implement
     those directly in the few architectures and be off with a much
     simpler design.'
