Subject: [PATCH 0/4] MIPS: Restartable sequences (rseq) support

This series implements MIPS support for restartable sequences, hooks up
the rseq syscall & implements MIPS support in the rseq selftests.

Applies atop Linus' master as of 2837461dbe6f ("Merge tag 'scsi-fixes'
of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi").

Thanks,
    Paul
