Please concentrate and stop the blabla:

36f0c423552d ("x86/boot: Disable RSDP parsing temporarily")

already explains what the deal is. This code was *purposefully* disabled
because we ran out of time and it broke a couple of machines. Don't make
me repeat all that - you were on CC on *all* threads and messages!

So we're going to try it again this cycle and if there's no fallout, it
will go upstream. If not, it will have to be fixed. The usual thing.

And I don't care if Kairui's patch fixes this one problem - judging by
the fragility of this whole thing, it should be hammered on one more
cycle on as many boxes as possible to make sure there's no other SNAFUs.

So go test it on more machines instead. I've pushed it here:
