To: Greg Kroah-Hartman, Jiri Slaby, kbd; +Cc: linux-kernel, Samuel Thibault
The current con_font_get/set API currently hardcodes a 32-pixel-tall
limitation, which only dates from the old VGA hardware which could not
handle taller fonts than that.
This change just adds a vpitch parameter to release this
constraint. Drivers which do not support vpitch != 32 can just return
EINVAL when it is not 32, font loading tools will revert to trying 32
and succeed.
This change makes the fbcon driver consider vpitch appropriately, thus
making it able to load large fonts.

The new KD_FONT_OP_GET/SET_TALL font operations allow to load fonts taller
than 32 pixels by dropping the VGA-specific vertical pitch limitation.
The new maximum font size has thus been raised to 64x128.
We however continue using the older font operations for smaller fonts, to
continue supporting older kernels.
