WARNING: There are errors in these changes that can cause a kernel 
crash.  In particular, union_allocvp() obtains the lwp to pass around 
from the cnp argument unconditionally.  However, the cnp argument is 
allowed to be NULL.  It is necessary to add an lwp * argument to 
union_allocvp() and use that instead.

I would suggest that all of these changes need to be audited very 
carefully, as it appears as if simple mechanical changes were made to 
get the code to compile.
