A repost of the SystemTAP/DTrace patches from http://lists.gnu.org/archive/html/qemu-devel/2010-11/msg00496.html
The patch is now split into two pieces. 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. This addresses the problem in previous versions of the patch where the tapset only worked for /usr/bin/qemu and no other binaries. Unfortunately SystemTAP does not allow for use of wildcards, so it was neccessary to go for a separate tapset file per emulator binary. Changes in v5: - The Makefile merge error is now fixed
