2   Provides CPU architecture specific functions that can not be defined
3   in the Base Library due to dependencies on the PAL Library
4 
5   The CPU Library provides services to flush CPU TLBs and place the CPU in a sleep state.
6   The implementation of these services on Itanium processors requires the use of PAL Calls.
7   PAL Calls require PEI and DXE specific mechanisms to look up PAL Entry Point.
8   As a result, these services could not be defined in the Base Library.
