Pull RISC-V fixes from Palmer Dabbelt:
 "This contains a pair of fixes to the RISC-V port:

   - The removal of our compat.h, which didn't do anything.

   - Fixes to sys_riscv_flush_icache to ensure it actually shows up.

     We're going to just call this a bug in the ABI, as it was always
     supposed to be there.

  I've given these a simple build+boot test, both individually and as
  the actual tag"
