Merge tag 'powerpc-5.7-6' of git://

Pull powerpc fixes from Michael Ellerman:

 - a fix for the recent change to how we restore non-volatile GPRs,
   which broke our emulation of reading from the DSCR (Data Stream
   Control Register).

 - a fix for the recent rewrite of interrupt/syscall exit in C, we need
   to exclude KCOV from that code, otherwise it can lead to
   unrecoverable faults.

Thanks to Daniel Axtens.
