Alexey Kardashevskiy 2001825efc KVM: PPC: Book3S HV: Avoid lockdep debugging in TCE realmode handlers ... The kvmppc_tce_to_ua() helper is called from real and virtual modes and it works fine as long as CONFIG_DEBUG_LOCKDEP is not enabled. However if the lockdep debugging is on, the lockdep will most likely break in kvm_memslots() because of srcu_dereference_check() so we need to use PPC-own kvm_memslots_raw() which uses realmode safe rcu_dereference_raw_notrace(). This creates a realmode copy of kvmppc_tce_to_ua() which replaces kvm_memslots() with kvm_memslots_raw(). Since kvmppc_rm_tce_to_ua() becomes static and can only be used inside HV KVM, this moves it earlier under CONFIG_KVM_BOOK3S_HV_POSSIBLE. This moves truly virtual-mode kvmppc_tce_to_ua() to where it belongs and drops the prmap parameter which was never used in the virtual mode.
