This series implements tests exercising the Statistical Profiling
Extensions.

This was tested with associated unmerged kernel [1] and QEMU [2]
series.

Depending on the comments, I can easily add other tests checking
more configs, additional events and testing migration too. I hope
this can be useful when respinning both series.

All SPE tests can be launched with:
./run_tests.sh -g spe
Tests also can be launched individually. For example:
./arm-run arm/spe.flat -append 'spe-buffer'

The series can be found at:
