For the reasons outlined here:

The whole point of the patch is to unify 32-bit and 64-bit wrt 
log-levels. The 32-bit version _is_ using KERN_DEFAULT implicitly and 
KERN_INFO is arguably wrong which is why I decided to go with the 
former. That way I don't need to go and audit all the callers of 
__show_regs() to see if KERN_WARN or some other level makes sense for them.
