>Description:
If _MODULE or _LKM, curlwp and curcpu() should be full function calls so 
that changes to the layout of cpu_info/lwp don't break module binary
compat. The x86 ports work like this but as far as I know it's still 
likely to be direct reference elsewhere.

>How-To-Repeat:
Code inspection.
>Fix:
See above.
