Merge tag 'riscv-for-linus-5.20-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Palmer Dabbelt:

 - Enabling the FPU is now a static_key

 - Improvements to the Svpbmt support

 - CPU topology bindings for a handful of systems

 - Support for systems with 64-bit hart IDs

 - Many settings have been enabled in the defconfig, including both
   support for the StarFive systems and many of the Docker requirements

There are also a handful of cleanups and improvements, as usual.
