For a little while around 4.9, Linux kernels that saw the radix bit in ibm,pa-features would attempt to set up the MMU as if they were a hypervisor, even if they were a guest, which would cause them to crash.
Work around this by detecting pre-ISA 3.0 guests by their lack of that bit in option vector 1, and then removing the radix bit from ibm,pa-features. Note: This now requires regeneration of that node after CAS negotiation.
