    [PATCH] vgacon: set vc_hi_font_mask correctly · a40920b4
    Bill Nottingham authored
    When allocating a new VC with vgacon_init(), the font is shared across all
    the VGA consoles.  However, the font mask was always set to the default
    value of zero in visual_init(), even if we were using 512 character fonts
    at the time.
    
    Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the
    console driver thinks it's already in 512 character mode.  This means that
    to *fix* it, you'd actually have to take the console out of 512 character
    mode and then set it back.
    
    The attached sets vc_hi_font_mask in vgacon_init() for any new consoles
    opened if the vgacon driver is already in 512 character mode, solving this.
    
    This bug goes back to 2.4.18 at least, probably earlier.
