I saw the original post, but I'm waiting on the review outcome before
approving a patch of this size with arch-specific changes.

I'd also like to see some response with regards x86 & ppc. I think sparc
may lack support, going forward, and I don't think Oracle were even
particularly maintaining Linux+SPARC. Last time I asked around, I
couldn't find anyone with a machine to test it on. It looks like there
may be some in the GCC compile farm now [0], so I'll try and take a
look, unless anyone has any better offers.
