Merge tag 'powerpc-4.18-3' of git://

Pull powerpc fixes from Michael Ellerman:
 "Two regression fixes, and a new syscall wire-up:

   - A fix for the recent conversion to time64_t in the powermac RTC
     routines, which caused time to go backward.

   - Another fix for fallout from the split PMD PTL conversion.

   - Wire up the new io_pgetevents() syscall.
