Here a repost of the last seccomp patch against current mainline
including the preempt fix. This changes the seccomp API from
/proc/<pid>/seccomp to a prctl (this will produce a smaller kernel)
and it adds a TIF_NOTSC that seccomp sets. Only the current task can
call disable_TSC (obviously because it hasn't a task_t param). This
includes Chuck's patch to give zero runtime cost to the notsc feature.

please send a patch-queue that is properly split-up: the bugfix, the API
change and the TIF_NOTSC improvement.
