It seems lately there has been a surge of interest in getting
niche x86 clones included in mainline (Voyager, numaq, Elan, etc).
I forget who it was who suggested it, but the idea came up of
using a similar approach to arm's subarchitecture support for x86.
The downsides would probably be a lot of code duplication,
The upside would be hiding away specialised code from the 99% of
people who don't need to see it. The Voyager patch for example
was ~150kb iirc, and was imo still quite intrusive even after
a first round of suggestions. Putting it into arch/x86-32/voyager/
would allow those that do care about it to do whatever they deem
necessary without inflicting dozens of #ifdefs and the likes
on the majority.
