There are 3 types of "indicator" associated with hotplug in the PAPR spec the "allocation state", "isolation state" and "DR-indicator". The first two are intimately tied to the various state transitions associated with hotplug. The DR-indicator, however, is different and simpler. It's basically just a guest controlled variable which can be used by the guest to flag state or problems associated with a device. The idea is that the hypervisor can use it to present information back on management consoles (on some machines with PowerVM it may even control physical LEDs on the machine case associated with the relevant device). For that reason, there's only ever likely to be a single update implementation so the set_indicator_state method isn't useful. Replace it with a direct function call. While we're there, make some small associated cleanups: * PAPR doesn't use the term "indicator state", just "DR-indicator" and the allocation state and isolation state are also considered "indicators". Rename things to be less confusing * Fold set_indicator_state() and rtas_set_indicator_state() into a single rtas_set_dr_indicator() function.
