    tracing: Move syscalls metadata handling from arch to core · c44fc770

    Most of the syscalls metadata processing is done from arch.
    But these operations are mostly generic accross archs. Especially now
    that we have a common variable name that expresses the number of
    syscalls supported by an arch: NR_syscalls, the only remaining bits
    that need to reside in arch is the syscall nr to addr translation.
    
    v2: Compare syscalls symbols only after the "sys" prefix so that we
        avoid spurious mismatches with archs that have syscalls wrappers,
        in which case syscalls symbols have "SyS" prefixed aliases.
