Ulrich, please understand that __get_cpuid() (which the discussion
here is about) is a gcc and llvm/clang feature weare are just making
use of. It used by various Linux software, and apparently doesn't work
entirely correctly on all CPUs in some corner case. The discussion is
about fixing gcc accordingly, and making it work, so that systemd all
all other software can work correctly.

If you think that gcc/llvm are bad for "reimplementing /proc/cpuinfo"
then please bring that up with those communities, but please stop
these fruitless discussions here.

Thank you for understanding,

Lennart
