(1) Extend NO_HZ support vs trace streaming support to other architectures (need
to add cpu idle notifiers and test).
(1) Make sure ltt-ascii kernel text dump fits well with streaming hooked into
cpu idle.

(1) Support CPUs with scalable frequency with a time-consistent increment and
with an approach scalable to SMP. (done for ARM OMAP3 UP only, but the OMAP3
approach should be tested and probably derived into an SMP implementation)

(3) Bring stack dump in sync with new lttng.
(4) Dump mounts. (to fix)
(4) Add Xen support. (Trace buffer desallocation needs to be fixed)
(4) integrate NPTL instrumentation (see
PTT).
(4) Probe calibration kernel module.
-(4) Make page faults detect nested fault without nesting 4 times in the page
-fault handler. (or use vmalloc_sync_all at each tracing module load)
(5) Add boot time tracing support.
(5) Integrate LTTng and lttd with LKCD.
