REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1119 Today's implementation reports CPU address size as 36 through CPU HOB. But when WinHost is running at 64bit, the system memory might be allocated above 2^36. It causes system asserts when DxeCore code tries to find the corresponding GCD entry for a given valid address. The patch uses 57 as the CPU address size which is maximum linear address size when 5-level paging is enabled in host OS. Using 64 seems more proper and a one-time change even 6-level paging might be invented. But it causes CoreInitializeGcdServices() assertion on following code: Entry->EndAddress = LShiftU64 (1, SizeOfMemorySpace) - 1; Because LShiftU64 expects SizeOfMemorySpace < 64. So to be practical, I didn't report 64 and change CoreInitializeGcdServices().
