OK, cool. The current code does support concatenated pgds for the hyp

For we get the time duration of (10msec timer + injection latency)
in timer_exec(), we substract the value of 10msec in timer_post()
to get the actual latency.

Besides using separate running times parameter, we add time limit
for loop_test to make sure each test should be done in a certain
time(5 sec here).

For some test in micro-bench can be time consuming, we add a
micro-bench test parameter to allow each individual test to specify
its running times.

Because micro-bench may send a large number of ITS commands, we
should handle ITS command queue wrapping as kernel instead of just
failing the test.

With the development of arm gic architecture, we think it will be useful
to add some performance test in kut to measure the cost of interrupts.
In this series, we add GICv4.1 support for ipi latency test and
implement LPI/vtimer latency test.
This series of patches has been tested on GICv4.1 suppo
Under certain circumstances, we need to further process microbench
test results, so we add test->post() in the microbench framework,
later patch will use that.
