Ben Gardon 70fb3e41a9 KVM: x86/mmu: Fix RCU usage in handle_removed_tdp_mmu_page ... The pt passed into handle_removed_tdp_mmu_page does not need RCU protection, as it is not at any risk of being freed by another thread at that point. However, the implicit cast from tdp_sptep_t to u64 * dropped the __rcu annotation without a proper rcu_derefrence. Fix this by passing the pt as a tdp_ptep_t and then rcu_dereferencing it in the function.
