MIPS: Add support for restartable sequences
Implement support for restartable sequences on MIPS, which requires 3
simple things:
- Call rseq_handle_notify_resume() on return to userspace if
TIF_NOTIFY_RESUME is set.
- Call rseq_signal_deliver() to fixup the pre-signal stack frame when
a signal is delivered whilst executing a restartable sequence
critical section.
- Select CONFIG_HAVE_RSEQ.
