Berrang=C3=A9 It is useful to know which CPUs satisfy each x86-64 ABI compatibility level, when dealing with guest OS that require something newer than the baseline ABI. These ABI levels are defined in: https://gitlab.com/x86-psABIs/x86-64-ABI/ and supported by GCC, Clang, glibc and more. Signed-off-by: Daniel P.
