Merge tag 'powerpc-5.4-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:
"Fix a kernel crash in spufs_create_root() on Cell machines, since the
new mount API went in.

Fix a regression in our KVM code caused by our recent PCR changes.

Avoid a warning message about a failing hypervisor API on systems that
don't have that API.

A couple of minor build fixes.

Thanks to: Alexey Kardashevskiy, Alistair Popple, Desnes A. Nunes do
Rosario, Emmanuel Nicolet, Jordan Niethe, Laurent Dufour, Stephen
Rothwell"
