Subject[patch 02/37] vt: fix canonical input in UTF-8 mode
2.6.25-stable review patch.  If anyone has any objections, please let us
know.

------------------
From: Samuel Thibault <samuel.thibault@ens-lyon.org>

commit c1236d31a1b9fc018b85e15a3e58e3601ddc90ae upstream

For e.g. proper TTY canonical support, IUTF8 termios flag has to be set as
appropriate. Linux used to not care about setting that flag for VT TTYs.

This patch fixes that by activating it according to the current mode of the
VT, and sets the default value according to the vt.default_utf8 parameter.
