Merge tag 'powerpc-6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:

 - Add support for building the kernel using PC-relative addressing on
   Power10.

 - Allow HV KVM guests on Power10 to use prefixed instructions.

 - Unify support for the P2020 CPU (85xx) into a single machine
   description.

 - Always build the 64-bit kernel with 128-bit long double.

 - Drop support for several obsolete 2000's era development boards as
   identified by Paul Gortmaker.

 - A series fixing VFIO on Power since some generic changes.

 - Various other small features and fixes.
