a79a3ca472 Fix a reversed argument which caused procfs_checkioperm() to always return 
"OK".  Add a few comments to avoid further confusion.

f9777e4a1c Fix the procfs hole described on current-users, similar to a fix for 
FreeBSD by Sean Eric Fagan, but a bit different.  This makes the checks
in the same places as sef's FreeBSD patch, but does not hardcode the
"kmem" group into the kernel, and also does a check identical to the
(3) and (4) checks in the NetBSD ptrace(2):

	(1) it's not owned by you, or is set-id on exec (unless
	    you're root), or

	(2) it's init, which controls the security level of the
	    entire system, and the system was not compiled with
	    permanently insecure mode turned on.

656b05ccf6 be a bit smarter about determining if files shouldn't be seen by the user. 
Also, DON'T allow a lookup to succeed on a file that's not visible!

699e3be9e9 add new procfs code, from Jan-Simon Pendry, jsp@sequent.com. 
This is pretty-much "virgin", so that diffs can be done later.
