Fix the graphic corruption issue on IA64 machines
VGA console driver can misunderstand the current mode(Text/Graphic) under "disable console blanking" setting. When "disable console blank" is set (blankinterval=0), "do_unblank_screen()" function returns without changing "blank_state", and when "blank_state" is "blank_off", "do_blank_screen() function returns without invoking sw->con_blank() function. That's why VGA console driver can misunderstand the current mode. Signed-off-by: Nobuhiro Tachino <ntachino@redhat.com> Signed-off-by: Taku Izumi <izumi2005@soft.fujitsu.com> Cc: "Antonino A.
