| ^~~~~~~~~~~~
We added the include of book3s/64/pkeys.h for pte_to_hpte_pkey_bits(),
but that header on its own should only be included when PPC_MEM_KEYS=y.
Instead include linux/pkeys.h, which brings in the right definitions
when PPC_MEM_KEYS=y and also provides empty stubs when PPC_MEM_KEYS=n.
Fixes: e4e8bc1df691 ("powerpc/kvm: Fix PR KVM with KUAP/MEM_KEYS enabled")
