[edk2-devel] [Patch 04/16] Vlv2TbltDevicePkg/PpmPolicy: Fix call to MP Services Protocol

[Michael D Kinney]

The NumberOfEnabledProcessors parameter to the MP Services
Protocol service GetNumberOfProcessors() is not optional and is
not allowed to be NULL.  Add the CpuEnabledCount local variable
and pass it into GetNumberOfProcessors().
