That's fair enough: if there's not enough resources to keep a feature maintainable 
upstream then it should not be upstream in that form.

This isn't just some driver we can let bit-rot in peace until it finds a 
maintainer (or not), without affecting anyone but users of that driver.

This is hundreds of usage sites of ugly code intermixed with critical pieces of 
assembly code that negatively affects the hackability of everything.

Also, with the feature missing completely, maybe someone finds a method to 
introduce it in a maintainable fashion, while with the feature included upstream 
there's very little pressure to do that. As a bonus we'd also win a workable dwarf 
unwinder.

Thanks,

	Ingo
