[Bug translator/10202] New: execute begin/end/error probes without preemption/irq blocking at all

["fche at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

Considering that we guarantee that begin/end/error probes run
sequentially, apart from any other probe types, we need not
add the preempt_disable() nor local_irq_save() for them.

This would in turn allow these probes to perform otherwise
improper operations, such as (guru-mode) embedded-c that
acquires full-fledged kernel-side locks for initialization
or a one-off report (like pfiles).
