KVM: Remove unused kvm_vcpu_gfn_to_pfn_atomic

For indirect sp, we disabled fast page fault for simplicity. A solution for indirect sp could be to pin the gfn, for example via -kvm_vcpu_gfn_to_pfn_atomic, before the cmpxchg. After the pinning: +gfn_to_pfn_memslot_atomic, before the cmpxchg. After the pinning: - We have held the refcount of pfn; that means the pfn can not be freed and be reused for another gfn. diff --git a/include/linux/kvm_host.h b/include/linux/kvm_host.h index b9b2e42e3fa7..45be36e5285f 100644 --- a/include/linux/kvm_host.h +++ b/include/linux/kvm_host.h @@ -1313,7 +1313,6 @@ void mark_page_dirty(struct kvm *kvm, gfn_t gfn); struct kvm_memslots *kvm_vcpu_memslots(struct kvm_vcpu *vcpu); struct kvm_memory_slot *kvm_vcpu_gfn_to_memslot(struct kvm_vcpu *vcpu, gfn_t gfn); -kvm_pfn_t kvm_vcpu_gfn_to_pfn_atomic(struct kvm_vcpu *vcpu, gfn_t gfn); int kvm_vcpu_map(struct kvm_vcpu *vcpu, gpa_t gpa, struct kvm_host_map *map); void kvm_vcpu_unmap(struct kvm_vcpu *vcpu, struct kvm_host_map *map, bool dirty); unsigned long kvm_vcpu_gfn_to_hva(struct kvm_vcpu *vcpu, gfn_t gfn); diff --git a/virt/kvm/kvm_main.c b/virt/kvm/kvm_main.c index f82131e7978b..141db5b79cd4 100644 --- a/virt/kvm/kvm_main.c +++ b/virt/kvm/kvm_main.c @@ -3035,12 +3035,6 @@ kvm_pfn_t gfn_to_pfn_memslot_atomic(const struct kvm_memory_slot *slot, gfn_t gf } EXPORT_SYMBOL_GPL(gfn_to_pfn_memslot_atomic); -kvm_pfn_t kvm_vcpu_gfn_to_pfn_atomic(struct kvm_vcpu *vcpu, gfn_t gfn) -{ - return gfn_to_pfn_memslot_atomic(kvm_vcpu_gfn_to_memslot(vcpu, gfn), gfn); -} -EXPORT_SYMBOL_GPL(kvm_vcpu_gfn_to_pfn_atomic); - kvm_pfn_t gfn_to_pfn(struct kvm *kvm, gfn_t gfn) { return gfn_to_pfn_memslot(gfn_to_memslot(kvm, gfn), gfn); |
