  riscv: export flush_icache_all to modules (2019-12-27 21:51:01 -0800)

----------------------------------------------------------------
RISC-V updates for v5.5-rc4

One important fix for RISC-V:

- Redirect any incoming syscall with an ID less than -1 to
  sys_ni_syscall, rather than allowing them to fall through into the
  syscall handler.

and two minor build fixes:

- Export __asm_copy_{from,to}_user() from where they are defined.
  This fixes a build error triggered by some randconfigs.

- Export flush_icache_all().  I'd resisted this before, since
  historically we didn't want modules to be able to flush the I$
  directly; but apparently everyone else is doing it now.
