Hi Linus,

Please pull two more powerpc fixes for 5.7. These are both regressions with
small "obviously correct" fixes.

cheers

  powerpc/64s: Disable sanitisers for C syscall/interrupt entry/exit code (2020-05-29 21:12:09 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.7 #6

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).

And 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.
