> The definition of IA32_MAP_ATTRIBUTE has 64 bits, and one of the bit
> field PageTableBaseAddress is from bit 12 to bit 52. This means if the
> compiler treats the 64bits value as two UINT32 value, the field
> PageTableBaseAddress spans two UINT32 value. That's why when building in
> NOOPT mode in IA32, the below issue is noticed:
> unresolved external symbol __allshl
> This patch fix the build failure by seperate field PageTableBaseAddress
> into two fields, make sure no field spans two UINT32 value.
