Merge tag 'riscv-for-linus-5.18-mw0' of git://git.kernel.org/pub/scm/linux/kernel...

Pull RISC-V updates from Palmer Dabbelt:

 - Support for Sv57-based virtual memory.

 - Various improvements for the MicroChip PolarFire SOC and the
   associated Icicle dev board, which should allow upstream kernels to
   boot without any additional modifications.

 - An improved memmove() implementation.

 - Support for the new Ssconfpmf and SBI PMU extensions, which allows
   for a much more useful perf implementation on RISC-V systems.

 - Support for restartable sequences.
