Subject: RE: [edk2-devel] [Patch V2 5/8] MdeModulePkg: Add UefiCpuPkg.dec to pass DependencyCheck

If components outside the UefiCpuPkg need access to the CpuPageTableLib, should we
consider moving CpuPageTableLib to MdePkg or MdeModulePkg?  There are many different
boot phases that need to crate/manage page tables, so we need to find the right
common location.  Perhaps the only part that needs to be moved is the lib class?

Mike
