I think we can only have platform specific LINTs. A single LINT that
compiles every piece of code must be able to compile all existing
pmap.c, machdep.c and other overlapping MD files in a single kernel.
Obviously an impossibility in this universe.
I think the hard part is: can we work with the elementary MD/MI
distinction we have now, or do we need to have a more fine grained
selection mechanism and if the latter, what?
Take for example powerpc or mips, do we need to distinguish between
little-endian and big-endian kernels? Do we need a selection based
on platform (rather than just architecture)?
