The change was done by modifying Linux's scripts/Lindent to use
100 columns instead of 80 and then manually reverting a few
changes that I didn't like, which I found by diffing with -b.

(nil) would be possible with a small change, but the standard leaves it
to the implementation and 0 is acceptable, IMO.

Merge branch 'ppc64/initial-drop-v7' of https://github.com/rhdrjones/kvm-unit-tests into HEAD

This series brings basic setup; starts a test's C entry point, main(),
and printf, exit, and malloc work. Three more series should follow this
one which must bring; vector support, mmu support, and smp support, at
which point I believe the framework could just evolve with the creation
of unit tests.

Tested on TCG and a P8 kvm_pr machine, and Laurent has tested it on
both a PowerMac G5 (kvm_pr) and a kvm_hv machine. I'm looking forward
to hearing more testing feedback from others though.
