Compiling issue for e5500 machines for the RC1 of kernel 7.0:

arch/powerpc/kvm/e500_mmu.c: In function 'kvmppc_e500_tlb_init':
arch/powerpc/kvm/e500_mmu.c:923:26: error: assignment to 'struct
tlbe_priv *' from incompatible pointer type 'struct tlbe_ref *'
[-Werror=incompatible-pointer-types]
923 |  vcpu_e500->gtlb_priv[0] = kzalloc_objs(struct tlbe_ref,
|                          ^
arch/powerpc/kvm/e500_mmu.c:928:26: error: assignment to 'struct
tlbe_priv *' from incompatible pointer type 'struct tlbe_ref *'

Temporary solution: # CONFIG_VIRTUALIZATION is not set

Please solve this issue.
