Subject: console: limit the range of VGACON_SOFT_SCROLLBACK_SIZE
From: Amerigo Wang <amwang@xxxxxxxxxx>
BuraphaLinux reported that we will trigger a mm warning when we
CONFIG_VGACON_SOFT_SCROLLBACK_SIZE=65536, this is because mm cann't
allocate so many pages. We should limit the range of
CONFIG_VGACON_SOFT_SCROLLBACK_SIZE, don't give a user any chance to
trigger that.
