MIPS: Add ksig argument to rseq_{signal_deliver,handle_notify_resume}
Commit 784e0300fe9f ("rseq: Avoid infinite recursion when delivering SIGSEGV") added a new ksig argument to the rseq_signal_deliver() & rseq_handle_notify_resume() functions, and was merged in v4.18-rc2. Meanwhile MIPS support for restartable sequences was also merged in v4.18-rc2 with commit 9ea141ad5471 ("MIPS: Add support for restartable sequences"), and therefore didn't get updated for the API change. This results in build failures like the following: CC arch/mips/kernel/signal.o arch/mips/kernel/signal.c: In function 'handle_signal': arch/mips/kernel/signal.c:804:22: error: passing argument 1 of 'rseq_signal_deliver' from incompatible pointer type [-Werror=incompatible-pointer-types] rseq_signal_deliver(regs); ^~~~ In file included from ./include/linux/context_tracking.h:5, from arch/mips/kernel/signal.c:12: ./include/linux/sched.h:1811:56: note: expected 'struct ksignal *' but argument is of type 'struct pt_regs *' static inline void rseq_signal_deliver(struct ksignal *ksig, ~~~~~~~~~~~~~~~~^~~~ arch/mips/kernel/signal.c:804:2: error: too few arguments to function 'rseq_signal_deliver' rseq_signal_deliver(regs); ^~~~~~~~~~~~~~~~~~~ Fix this by adding the ksig argument as was done for other architectures in commit 784e0300fe9f ("rseq: Avoid infinite recursion when delivering SIGSEGV").
