Simplified the code a bit.
Updated Linux config for 3.10.4. Enabled kvmclock.
Some random stuff I forgot to commit...
Removed option to disable offloads.
Added simple tracing infrastructure.
Trace when we go BUSY again.
Move more of IRQ logic into poll_irq.
Removed WENT_BUSY trace event. If tracing is enabled and no trace file is given, trace output is trace-PID.
Updated benchmarking and plotting scripts
Fixed getting username when on console.
