[libvirt] [PATCH 0/6] Improvements to CPU frequency reporting

[Andrea Bolognani]

A few steps towards eventually fixing

  https://bugzilla.redhat.com/show_bug.cgi?id=1206353

The commit message for patch 6/6 contains most of the rationale,
previous patches are cleanups. If not for the new test case added
with patch 1/6, the overall diffstat would be negative.

Andrea Bolognani (6):
  tests: Add host CPU data for Moonshot (RHEL 7.4)
  util: Introduce virHostCPUGetInfoParseCPUInfo()
  util: Introduce virHostCPUGetInfoParseCPUFrequency()
  util: Tweak virHostCPUGetInfoParseCPUFrequency()
  util: Tweak s390(x) case for CPU frequency
  util: Don't report CPU frequency for ARM hosts
