I'm not sure what you think you're gaining from this over the current 
implementation.  But, the reason you're losing is because grouplist is a 
user-space address and you're treating it as if it were a kernel-space 
address.  That works fine for memory models where all of the user process's 
VM is mapped in kernel mode at the same addresses, but not for models where 
that is not the case.
