the semantics in that the returned filename to use is now a kernel
pointer rather than a user space pointer. This required changing the
arguments to the CHECKALT*() macros some and changing the various system
calls that used pathnames to use the kern_foo() functions that can accept
kernel space filename pointers instead of calling the system call
directly.
- Use kern_open(), kern_stat(), kern_lstat(), kern_fstat(), kern_access(),
kern_truncate(), kern_pathconf(), kern_execve(), kern_select(),
kern_setitimer(), kern_getitimer(), kern_statfs(), and kern_fstatfs().
