[Bug tapsets/11444] Check that no pt_regs*-processing functions are /* unprivileged */

------- Additional Comments From fche at redhat dot com  2010-06-11 17:51 -------
Reviewed all tapset functions.  Ones that
use CONTEXT->regs:

registers_valid() valid, only nullness test
user_mode() valid, only to test user mode flag in MSR
stp_pid() only mentioned for completeness; uses task_pt_regs() only

ucontext-unwind.stp:*: unsure, maybe should task_pt_regs() only; mjw?

utrace.stp: Ditto. Actually, should rewrite src/tapset-utrace.cxx
            to use expression embedded-c and remove these tapset fns entirely.
