[Qemu-devel] [kvm-unit-tests PATCHv5] ARM PMU tests

[Christopher Covington]

Changes from v4:
* Add Drew's Reviewed-by to first patch.
* Explain use of 32-bit cycle count values in AArch32.
* Zero-initialize pmu_data struct before use in check_cycles_increase and 
check_cpi. While the insistence on not using memset is entirely my own vanity, 
I blame the funny syntax on https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119 
(adds extra set of braces) and checkpatch (adds spaces).
* Improve formatting of inline assembly and better explain why so much code 
must be inline assembly.
