[PATCH 00/75] TTY updates for 2.6.29-rc

[Alan Cox <alan@lxorguk.ukuu.org.uk>]

There are several chunks to this. The main thrust is extracting common code
into the tty layer and tidying up. Further lock_kernel removal is done (notably
Joe Peterson has removed in from most of n_tty now). Ptys get namespaces for
container usage.
