[PATCH] Fix broken kernel headers preventing ARM build

[Russell King <rmk+lkml@arm.linux.org.uk>]

And this can be the first of the series.  Note that this is NOT a
cleanup, but a build fix, so _is_ immediate -rc1 material.
-----

As a result of 894673ee6122a3ce1958e1fe096901ba5356a96b, the ARM
architecture is more or less unbuildable - only one defconfig appears
to build, with all others erroring out with:

Essentially, root_dev.h uses MKDEV and dev_t, but does not include any
headers which provide either of these definitions.  The reason it worked
previously is that linux/tty.h just happened to include the required
headers for linux/root_dev.h.
