I first noticed this when CTRL-S stopped working as 'search-forward' in Emacs, but it seems the same problem exists in /usr/bin/vi, vim, bash and a few other programs that I tested. With a kernel before the mpsafetty changes, I can fire up /usr/bin/vi and type in insert-mode `^V^S'. This correctly inserts a ^S character. With a kernel from svn revision /head@181939 ^V no longer quotes the next byte in vi(1) and other programs.
