    lib/vdso: Provide generic VDSO implementation · 00b26474
    Vincenzo Frascino authored
    In the last few years the kernel gained quite some architecture specific
    vdso implementations which contain very similar code.
    
    Introduce a generic VDSO implementation of gettimeofday() which will be
    shareable between architectures once they are converted over.
    
    The implementation is based on the current x86 VDSO code.
