Subject: Fix the graphic corruption issue on IA64 machines
From: izumi <izumi2005@xxxxxxxxxxxxxxxx>
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.
