Hello Paolo,

git clone https://git.kernel.org/pub/scm/virt/kvm/kvm.git -b 
kvm-e500-bisection-rebase a

git checkout 0096d3855a5e80b9d4e43e5a291e8c79aa4abbc2

Output:

... HEAD is now at 0096d3855a5e KVM: PPC: e500: Use __kvm_faultin_pfn() 
to handle page faults

make -j8 CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc oldconfig

make -j8 CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc uImage

The host kernel and the guest kernel boots with "-enable-kvm" so KVM HV 
works.

commit 15ac24da3251e47fe3a63ea52d8c5ecb0b26b02c (HEAD -> 
kvm-e500-bisection-rebase, origin/kvm-e500-bisection-rebase)

I tested the top additionally and the host and guest boot.

BTW, I also tested KVM PR on my P.A. Semi Nemo board yesterday. KVM PR 
isn’t affected. PA6T-1682M is a Book3S SoC with AltiVec support.

Thanks,
Christian
