Merge tag 'riscv-for-linus-4.21-mw1' of git://git.kernel.org/pub/scm/linux/kernel...

Pull RISC-V updates from Palmer Dabbelt:
 "We don't have many patches for this merge window, probably because
  everything has been a bit busy with the holidays and conferences. The
  only big user-visible change is to move over to an SBI-based earlycon
  instead of our arch-specific early printk support.

  The only outstanding patch set I know of is the audit patch set, which
  I've managed to make a mess of and will attempt to clean up"
