    Subject[PATCH] Add the ability to layer another driver over the serial driver
    This is a set of three patches to allow adding another driver on top of
    the current serial driver without too much change to the serial code.
    This is more for comments right now, it is probably not ready for real
    use yet.

    The patches are too big to post here, so I'm putting them on

    The three patches are:

    * serial-remove-tty-struct-from-driver.patch - A general patch to
    remove the tty includes from the low-level serial drivers. Only
    fixes the 8250 for now.

    * serial-allow-in-kernel-users.patch - The actual patch that adds
    the layered driver to the serial core.

    * serial-8250-cleanup.patch - Add support for the layered driver
    and poll to the 8250 uart.

    This is for a serial interface to an IPMI controller. Note that I
    don't really like this very much for a number of reasons, but the IPMI
    driver has features that only work in-kernel, like extending the
    watchdog timer on a panic to allow kdump to operate without a reboot
    and storing panic information in the IPMI event log. So you really
    can't write a userland-only interface for this and keep those

    It is also not really possible to add this on top of the tty code
    because it has to be able to run at panic time, and the tty code
    doesn't have a clean place to interface this from what I could
