This leads to some confusion in the kernel build because it redefines  
these names in iscsi and bktr which do not actually grab the token, but  
define them as empty. I think it breaks LINT, too.

Also, it's kind of confusing to give them the same name as FreeBSD, since  
tokens are not hard locks.

My suggestion is that we should explicitly grab the token in whatever code  
that is supposed to use the macros from <sys/proc.h> (I guess it's for  
drm2), instead of hiding it behind unclear names that suggest something  
else.
