It looks like symbol waitqueue_lock is not exported as a module symbol
when the 2.1.122 kernel is compiled without SMP support. However this
symbol is referenced unconditionally by several inline routines in
<linux/sched.h>.
This prevents some modules (including OSS) from being loaded in UP
compiled systems.
UP and SMP modules cannot be intermixed anyways, the system will
likely crash if a module compiled for one is load into the other.
In fact there should be a special module mechanism for this purpose,
preventing the loading of modules into the wrong kind of kernel (UP
vs. SMP). I thought Alan did something like this already, or did he
make this happen only when module symbol versioning is on?
