+/** @file
+  Provides CPU architecture specific functions that can not be defined
+  in the Base Library due to dependencies on the PAL Library
+  
+  The CPU Library provides services to flush CPU TLBs and place the CPU in a sleep state.
+  The implementation of these services on Itanium processors requires the use of PAL Calls.
+  PAL Calls require PEI and DXE specific mechanisms to look up PAL Entry Point.
+  As a result, these services could not be defined in the Base Library.
