You need:
6964e6a4e489 ("KVM: PPC: Book3S HV: Do SLB load/unload with guest LPCR
value loaded", 2018-01-11)
00608e1f007e ("KVM: PPC: Book3S HV: Allow HPT and radix on the same core
for POWER9 v2.2", 2018-01-11)
cda4a1473313 ("KVM: PPC: Book3S HV: Fix duplication of host SLB
entries", 2018-03-22)
The last one is in my kvm-ppc-fixes branch on kernel.org but not in the
KVM tree or Linus's tree yet.
