AX25.027

[iialan@iifeak.swan.ac.uk (Alan Cox)]

I've placed the updates for AX25.027 on the sunacm.swan.ac.uk archive site.
These are the (probably final) changes for the current AX.25 set before I
go for hacking with KA9Q's generously GPL'd code for Linux 1.3.x.

This fixes

        o       SO_DEBUG being overly security concious
        o       AX.25 socket crashes when a buffer is queued a long time
                in the PI or AX.25 drivers and the socket is destroy too
                early
        o       Potential queue walking problems caused by missing interrupt
                protection
        o       PI2 driver changes for new architecture independant interrupt
                handler (basically irq number is passed in not grabbed out of
                the interrupt stack).
