    kconfig: allow use of relations other than (in)equality · 31847b67
    Jan Beulich authored
    Over the years I found it desirable to be able to use all sorts of
    relations, not just (in)equality. And apparently I'm not the only one,
    as there's at least one example in the tree where the programmer
    assumed this would work (see DEBUG_UART_8250_WORD in
    arch/arm/Kconfig.debug). Another possible use would e.g. be to fold the
    two SMP/NR_CPUS prompts into one: SMP could be promptless, simply
    depending on NR_CPUS > 1.
    
    A (desirable) side effect of this change - resulting from numeric
    values now necessarily being compared as numbers rather than as
    strings - is that comparing hex values now works as expected: Other
    than int ones (which aren't allowed to have leading zeroes), zeroes
    following the 0x prefix made them compare unequal even if their values
    were equal.
