This removes the RMA limit on powernv platform, which constrains
early allocations such as PACAs and stacks. There are still other
restrictions that must be followed, such as bolted SLB limits, but
real mode addressing has no constraints.  

For radix, should we consider making the PACAs chip/node local ?

Yes that's the main goal of the series. I had NUMAization patches
at the end. Just dropped them for now because some of them need
toplogy information that's not available (that's why I was asking
about moving unflattening earlier in boot, but we may be able to
move allocations later too).

Thanks,
Nick
