    Well, as long as 8K stacks are an option we'll never get all the code
    that doesn't work properly with 4K stacks fixed. We *might* get all
    the in-tree code fixed eventually, but there's still going to be lots
    of out-of-tree code that will keep depending on 8K stacks. And as long
    as 4K stacks are not reliable, distributions are stick with 8K for
    their kernels, people who build their own kernel are probably also
    going to stick to 8K most of the time, since that's the default. This
    makes the 4K stack option fairly pointless for most users.

    If we consider 4K stacks broken, not used much, then we should just
    get rid of that option. That would remove a config choice (of which we
    have IMHO way too many already) and it would remove code that we then
    no longer need to maintain.

    If, on the other hand, we consider 4K stacks to be the superior
    solution, then we should work to get all code fixed to be able to
    handle it so that it's actually something distros will start to enable
    so that we can eventually get rid of the 8K stack option alltogether.
    Making 4K stacks default and no longer a debug option is just the
    first step in that direction.
