Merge tag 'powerpc-4.17-7' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fix from Michael Ellerman:
"Just one fix, to make sure the PCR (Processor Compatibility Register)
is reset on boot.
Otherwise if we're running in compat mode in a guest (eg. pretending a
Power9 is a Power8) and the host kernel oopses and kdumps then the
kdump kernel's userspace will be running in Power8 mode, and will
SIGILL if it uses Power9-only instructions.
Thanks to Michael Neuling"
