Add function to get Page Table entry bits This commit adds a helper function to get Page Table entry bits and control a configuration of first levels page walks (non-PTE). Change-Id: I85666ffae8e89a193d1ac4a065c2b84b814d47ec

/*
Optimize binaries' size by adjusting linkage of constants in headers When header is included for the first time in translation unit, then preprocessor simply copy-pastes its content. If we define a constant in a header file and this constant has internal linkage then each and every translation unit, which includes this header will have its own copy of this constant. C++17 introduces inline variables, which are meant to allow creation of variables in header files, which do not cause multiple instances. The inline variable has a single instance when: - constexpr is used without static (constexpr implicitly implies inline) - inline is used without static - inline const is used without static (const does not imply internal linkage when used with inline) Signed-off-by: Patryk Wrobel <patryk.wrobel@intel.com>
