Changlong:
Thanks to David's review, there are some changes:
- add kvm-events compile-depend files to tools/perf/MANIFEST
- fix some typos and little clean up
- rebase it on -tip tree
The output example is following:
#./perf kvm-events report --event mmio --vcpu 3
Analyze events for VCPU 3:
MMIO Access Samples Samples% Time% Avg time
0xfee00380:W 29688 61.16% 64.52% 3.37us ( +- 0.86% )
