definitely - but often there are constraints on the numeric value that
are not spelled out in the Kconfig language. (alignment, granularity,
etc.)

MAXSMP is still useful, as it would still be rather unlikely for all
numeric values to go to the max at once. The other idea is that with it
'make allyesconfig' really puts all build-time limits up to the max.
