[kvm-unit-tests,v8,00/10] MTTCG sanity tests for ARM

Hi,

It's been a long time since I last posted these but I'd like to
incorporate some MTTCG tests into QEMU's upstream acceptance tests and
a first step is getting these up-streamed. Most of the changes are
fixing up the numerous checkpatch failures (although isaac remains
unchanged and some warnings make no sense for kvm-unit-tests).

I dropped an additional test which attempts to test for data flush
behaviour but it still needs some work:
