And some my additions in GLIBC_* namespace have now appeared by https://github.com/openjdk/jdk/commit/d50b6eb342e9ec96d1a01dafc317e00725dc84c0 also in the upstream CPU_* namespace. They were missing in the CPU_* namespace when I was implementing it. So we can remove the duplicity from GLIBC_* namespace.
