[PATCH 1/6] allow LEGACY_PTYS to be set to 0

[Greg Kroah-Hartman <gregkh@suse.de>]

From: Kay Sievers <kay.sievers@vrfy.org>

The count of legacy pty devices can be set by a kernel commandline
parameter. For the distro kernel, we would like to disable all pty's
by default, but keep the opportunity to request devices on the kernel
commandline.
