Yes, you're right - it will. Ho hum, this means that Alpha has the bug
too, though it isn't a big problem there, because the ports aren't
accessed often (not in gettimeofday, not in timer interrupt).
> Am i missing something ?
No, I missed that the spinlock isn't defined on alpha probably also
other archs that use the i8253.
Possible ways to fix that:
* #ifdef the spinlock code to __i386__ only.
* Add an otherwise unused i8253_lock to other archs.
* Add the spinlock to other archs and make them use it.
