If that's the case then Ralf's mips-queue tree isn't in linux-next :(

That's a hard call without knowing what's going on in mipsworld.  If
these patches applied to current mainline we could do it all as one
patch and, with suitable acks, slap it into 2.6.32.

Are these fixes also appropriate to 2.6.31.x and earlier?  If so,

that's another reason to prepare the patches against current mainline
and just trample over the mips devel queue.
