No.

I will disable that ISA config option. We're not randomly making old
drivers available on modern platforms. Really.

We're not suddenly enabling ISA on x86-64 after having successfully
gotten rid of that insane crap long long ago.

If you have *specific* dribvers that are actually relevant for some
reason, make those ones available based on other options. For example,
we've had the ISA_DMA_API config option to say "we support a subset of
ISA, even when we don't actually want to ever see actual plug-in ISA
cards".

Your patch already resulted in having to add several cases of

- depends on ISA
+ depends on X86 && ISA

because you tried to randomly widen what "ISA" meant. No. No no no.

No more "let's randomly change what ISA is". Do this enabling one
driver at a time, or not at all. I'm not at all interested in seeing
some kind of generic "we will support random shit on modern platfoms"
crap. 99% of all drivers that depend on ISA have no maintainership,
and will never get any maintainership.
