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_access(), kern_execve(), kern_mkfifo(), kern_mknod(), kern_setitimer(), kern_getrusage(), kern_utimes(), kern_unlink(), kern_chdir(), kern_chmod(), kern_chown(), kern_symlink(), kern_readlink(), kern_select(), kern_statfs(), kern_fstatfs(), kern_stat(), kern_lstat(), kern_fstat(). - Drop the unused 'uap' argument from spx_open(). - Replace a stale duplication of vn_access() in xenix_access() lacking recent additions such as MAC checks, etc. with a call to kern_access().
