    x86/vdso: Add clock_gettime64() entry point · 22ca9622
    Vincenzo Frascino authored
    Linux 5.1 gained the new clock_gettime64() syscall to address the Y2038
    problem on 32bit systems. The x86 VDSO is missing support for this variant
    of clock_gettime().
    
    Update the x86 specific vDSO library accordingly so it exposes the new time
    getter.
