These patches fix most of the cases where it went wrong in the VT code. What remains is related to fbcon as well and so not part of this series. This run fixes concerns raised on review and adds one more patch for a problem which doesn't cause visible effects. These patches were prepared to apply on tty-next. Zsolt Kajtar (4): tty/vt: 8th bit location in vc_uniscr routines tty/vt: Prevent 8th bit corruption with soft cursor tty/vt: Fix unreadable kernel messages on vgacon tty/vt: use correct attribute mask in do_update_region drivers/tty/vt/vt.c | 40 ++++++++++++++++++++++++++-------------- 1 file changed, 26 insertions(+), 14 deletions(-) -- 2.30.2
