[PATCH] vgacon: set vc_hi_font_mask correctly
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.
