#     
#     Pull RISC-V fixes from Paul Walmsley:
#      "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"
