Subject: [PATCH 0/8] perf tools: Add Intel PT support for jitdump

Hi

In order to use Intel PT with jitdump, changes are needed
because Intel PT uses TSC as a timestamp not the monotonic clock.

These patches enable TSC to be used which allows the following
using a simple HelloWorld java app:

	perf record -e intel_pt//u -o java.perf.data java -agentpath:/home/ahunter/git/linux-perf/tools/perf/jvmti/libjvmti.so HelloWorldApp

	perf inject -i java.perf.data --jit -o java.perf.data.jitted

	perf report -i java.perf.data.jitted

	perf script -i java.perf.data.jitted | less

Note, there will be some decoder errors because not all the
generated code is reported to the agent.

Lazily, there is also an unrelated patch:

	perf tools: Use 64-bit shifts with (TSC) time conversion"
