This series implements a few RTAS hypercalls in tests/libqos that, used together, implement the DRC state transition described in PAPR 2.7+, 13.4.
This started as an attempt of implementing hot unplug qtests for the sPAPR machine but I've found a few issues that will require more time solving: - CPU hot unplug: for some reason the machine freezes after the callback is returned. - LMB hot unplug: not supported by the sPAPR machine if not set in CAS. I have a feeling that the CPU hot unplug issue might be related with the lack of CAS negotiation step as well, but only way to be sure is to further understanding how the CAS negotation interfere with the device hot unplug. If needed we'll have to implement the client architecture support hypercall as well in the future. Until then, I believe these hypercalls have a value of their own and are worth being pushed upstream.
