commit 9f161439 upstream. Commit 4c21b8fd ("MIPS: seccomp: Handle indirect system calls (o32)") fixed indirect system calls on O32 but it also introduced a bug for MIPS64 where it erroneously modified the v0 (syscall) register with the assumption that the sycall offset hasn't been taken into consideration. This breaks seccomp on MIPS64 n64 and n32 ABIs. We fix this by replacing the addition with a move instruction.
