  checksyscalls: Unconditionally ignore fstat{,at}64 (2021-10-07 17:16:28 -0700)

----------------------------------------------------------------
RISC-V Fixes for 5.15-rc5

* A pair of fixes (along with the necessary cleanup) to our VDSO, to
  avoid
* A fix to checksyscalls to teach it about our rv32 UABI.
* A fix to add clone3() to the rv32 UABI, which was pointed out by
  checksyscalls.
* A fix to properly flush the icache on the local CPU in addition to the
  remote CPUs.
