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.

calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64)

architectures built with Clang (all released versions), whereby the stack

frame gets blown up to well over 5k. This would cause an immediate kernel

panic on most architectures. We'll revert this when the following bug report

has been resolved: https://github.com/llvm/llvm-project/issues/41896.
