An update of the SystemTAP/DTrace patches from http://lists.gnu.org/archive/html/qemu-devel/2010-11/msg00563.html
The first patch contains the generic DTrace tracing backend support. The second patch contains additional pieces for SystemTAP to generate a tapset for each of the qemu-system-XXX binaries, to simplify life for admins wanting to use the tracing backend. Changed in v6: - Fix handling of probes with no-args in DTrace provider - Generate one tapset per target, for both system and user emulators - Re-write command line arg parsing in tracetool so it doesn't assume a particular ordering of args - Change '-s' to '--stap' in tracetool to avoid confusion - Pass full binary name into tracetool
