Hi Conor,

  Thank you, I should not have just used defconfig without allesconfig.
  It has been corrected in PATCH v2 [0] as follows.

  v1 -> v2: makes compilation pass with allyesconfig instead of
  defconfig only, also satisfy scripts/checkpatch.pl.
  - (__asm__ __volatile__ (RISCV_FENCE_ASM(p, s) : : : "memory"))
  + ({ __asm__ __volatile__ (RISCV_FENCE_ASM(p, s) : : : "memory"); })

  I've updated patch v3[https://marc.info/?l=linux-kernel&m=170783431129245]
  Please let me know if you have any further questions or suggestions.
