There is a bug in original EdkModulePkg\Library\EdkUefiRuntimeLib\Common\RuntimeLib.c. Originally, if a driver did not produce a <SetVirtualAddressMapCallBack>'s function, EFI_EVENT_SIGNAL_VIRTUAL_ADDRESS_CHANGE notify event will not be created in RuntimeDriverLibConstruct(), This is a bug, because at least, mRT pointer need to be converted for runtime service.
This bug will lead runtime interface GetMonoCount() failure because EdkModulePkg\Universal\MonotonicCounter\RuntimeDxe driver does not produce any <SetVirtualAddressMapCallBack>'s function. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@2343 6f19259b-4bc3-4df7-8a09-765794883524
