Transactional Synchronization Extensions are supported on certain Intel's CPUs only, hence can be put under CONFIG_INTEL build option. The whole TSX support, even if supported by CPU, may need to be disabled via options, by microcode or through spec-ctrl, depending on a set of specific conditions. To make sure nothing gets accidentally runtime-broken all modifications of global TSX configuration variables is secured by #ifdef's, while variables themselves redefined to 0, so that ones can't mistakenly be written to.
