Merge tag 'riscv-for-linus-4.19-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux

Pull RISC-V fixes from Palmer Dabbelt:
 "RISC-V Fixes and Cleanups for 4.19-rc2

  This contains a handful of patches that filtered their way in during
  the merge window but just didn't make the deadline. It includes:

   - Additional documentation in the riscv,cpu-intc device tree binding
     that resulted from some feedback I missed in the original patch
     set.

   - A build fix that provides the definition of tlb_flush() before
     including tlb.h, which fixes a RISC-V build regression introduced
     during this merge window.

   - A cosmetic cleanup to sys_riscv_flush_icache()"
