[PATCH v5 0/8] cxl: Process event logs

[Ira Weiny <ira.weiny@intel.com>]

This code has been tested with a newer qemu which allows for more events to be
returned at a time as well an additional QMP event and interrupt injection.
Those patches will follow once they have been cleaned up.

The series is now in 3 parts:

       1) Base functionality including interrupts
       2) Tracing specific events (Dynamic Capacity Event Record is defered)
       3) cxl-test infrastructure for basic tests
