[Qemu-devel] [PATCH] simpletrace: fix process() argument count

[Stefan Hajnoczi]

The simpletrace.process() function invokes analyzer methods with the
wrong number of arguments if a timestamp should be included.  This patch
fixes the issue so that trace analysis scripts can make use of
timestamps.
