Subject: [PATCH 0/2] Enlarge the storage of chars in virtual terminal

Greetings

The motivation is display much more characters on the
framebuffer console than 512. If this is done, foreign
languages can be easily rendered with currently supported
utf-8 encoding.

In order to display fonts with more than 512 chars,
the storage of one char in virtual terminal must be
enlarged. Currently vt holds one u16 for every character,
7 bits for attributes. The patches extend it into u32.

Virtual terminal is referenced by many other drivers.
If it has been changed, others must be changed as well.
Change all of them may spend 1 or more weeks, and the
patches include the change of fbcon. So I just put the
done part here and wish to have your advices.

Any reply is appreciated, thank you.

Frank Pan
