Summary: Comparing m_page_size against kInvalidPageSize was resulting in a warning about comparing integers with different signs. Since kInvalidPageSize isn't used anywhere outside of MachVMMemory.cpp, we can readily transform it into a static const vm_size_t with the correct value to avoid the sign comparison warnings.
