    vgacon: remove software scrollback support · 973c096f
    Linus Torvalds authored
    Yunhai Zhang recently fixed a VGA software scrollback bug in commit
    ebfdfeea ("vgacon: Fix for missing check in scrollback handling"),
    but that then made people look more closely at some of this code, and
    there were more problems on the vgacon side, but also the fbcon software
    scrollback.
    
    We don't really have anybody who maintains this code - probably because
    nobody actually _uses_ it any more.  Sure, people still use both VGA and
    the framebuffer consoles, but they are no longer the main user
    interfaces to the kernel, and haven't been for decades, so these kinds
    of extra features end up bitrotting and not really being used.
    
    So rather than try to maintain a likely unused set of code, I'll just
    aggressively remove it, and see if anybody even notices.  Maybe there
    are people who haven't jumped on the whole GUI badnwagon yet, and think
    it's just a fad.  And maybe those people use the scrollback code.
    
    If that turns out to be the case, we can resurrect this again, once
    we've found the sucker^Wmaintainer for it who actually uses it.
