That argument is more than a little unfair, Ingo.  Voyager support used 
to be in mainline.

It got yanked, and now you are adding all sorts of barriers for its 
re-inclusion?

And out of curiosity, who reviewed and accepted the patch that broke 
Voyager's build?

Don't get hopping mad just because someone doesn't move at your warp 
speed.  Just mark it CONFIG_BROKEN and __move on__.

Taking my vendor hat OFF for a second, this sort of stuff just smacks 
"corporate Linux" to me.  What happened to the Linux community that 
encouraged enthusiasts who wanted to keep alive some obscure code in the 
kernel?

I think it will be a sad day when somebody, in an Ingo-like fit of 
cleaning, rm -rf's m68k, alpha, and the like.

I am not an x86 maintainer, of course, but it hardly seems likely that 
the existence of Voyager in the x86 tree is a huge, crushing, 
soul-sucking burden.

A world without dinosaur architectures is a world without fun :)
