Message-Id: <684d63adc58a29183d7ff4161b3ed93f09896375@dist-git>

Subject: [PATCH] tests: Add test infrastructure for qemuMonitorGetCPUInfo
https://bugzilla.redhat.com/show_bug.cgi?id=1097930
https://bugzilla.redhat.com/show_bug.cgi?id=1224341
As the combination algorithm is rather complex and ugly it's necessary
to make sure it works properly. Add test suite infrastructure for
testing it along with a basic test based on x86_64 platform.
(cherry picked from commit f8638471d7f203a654e3b157dfd042a2239e2cb0)
