Merge tag 'for-5.20/parisc-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc updates from Helge Deller:
 "One real bugfix to change the io_pgetevents_time64() syscall to use
  the compat implementation when running in compat mode, otherwise the
  signed int32 parameters min_nr and nr will be incorrectly handled as
  unsigned int64 values.

  Other than that just small cleanups:

   - hardware database housekeeping and proper /proc/iomem output

   - add proper function exit code if probe functions fail

   - drop stale variables (pa_swapper_pg_lock)

   - drop unneccessary zero-initializations

   - typo fixes in comments"
