I Found a few pmu test failures when ran againt KVM/queue branch with pmu
disabled(enable_pmu=0), and posted a few fixup patches for the issues.
Maintainers reviewed and commented actively, which makes the fixup patches
evolved into this series. Besides two fixup patches, there're another two
cleanup patches included.

patch 1: Cleanup patch. Use report_skip() instead of printf() to make
output logs clean.
patch 2: Cleanup patch. Add helpers to check platform supported pmu
capabilities.
patch 3~4: Fixup patches. Fix test failures seen when pmu_enable=0.


Yang Weijiang (4):
  x86: Use report_skip to print messages when tests are skipped
  x86: Use helpers to fetch supported perf capabilities
  x86: Skip perf related tests when platform cannot support
  x86: Check platform pmu capabilities before run lbr tests
