# Merge: 900db1504704 2f26ed1764b4

#     Merge tag 'powerpc-5.7-6' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     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.
