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 possibly use would e.g. be to fold the
two SMP/NR_CPUS prompt 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.

Question: Should "<>" and/or "==" then perhaps also be permitted?

Just a quick reply (three odd lines I noted while unsuccessfully trying
to apply this on top of my local changes).

You mean as aliases for "!=" and "="?

Argh - yes, definitely; I even have a note in the patch that these
should get dropped, but I managed to ignore that note.

If all you have to change is drop those three lines, I'll play with this
patch anyway, as I finally maltreated it enough to apply on top of my
local changes.

Yes, unless other comments require me to make further changes,
this is all I currently see needing adjustment and re-sending.
