    x86: Adjust tst-cpu-features-supports.c for GCC 11
b1dca6
    
b1dca6
    Check HAS_CPU_FEATURE instead of CPU_FEATURE_USABLE for FSGSBASE, IBT,
b1dca6
    LM, SHSTK and XSAVES since FSGSBASE requires kernel support, IBT/SHSTK/LM
b1dca6
    require OS support and XSAVES is supervisor-mode only.
