[PATCH] riscv: enable sys_clone3 syscall for rv64

[Paul Walmsley]

Enable the sys_clone3 syscall for RV64.  We simply include the generic
version.

Tested by running the program from

   https://lore.kernel.org/lkml/20190716130631.tohj4ub54md25dys@xxxxxxxxxx/

and verifying that it completes successfully.
