Revision: 6452
http://svn.sv.gnu.org/viewvc/?view=rev&root=qemu&revision=6452

Log Message:
-----------
Log reset events (Jan Kiszka)
Original idea&code by Kevin Wolf, split-up in two patches and added more
archs.
This patch introduces a flag to log CPU resets. Useful for tracing
unexpected resets (such as those triggered by x86 triple faults).
