Porting kernel code from freebsd.

[Jonathan Smith <maligned_(_at_)_attcanada_(_dot_)_net>]

Ive been experimenting some with the trusted system functionality code
thats being done for freebsd by Robert Watson specifically the auditing
code (its extremely experimental in nature) and I was wondering wether
or not there are any cavets in porting kernel space code from freebsd?
The kernel space code im working with has needed a few changes but
appears to compile with out incident except for the rearangment of some
of the files as there is no sys/sysproto.h and it seems there is no _PAD
macro or function within the files I have been dealing with. If anyone
is aware of any cavets that affect this issue could contact me it would
be greatly appreciated.
