KVM: No need to retry for hva_to_pfn_remapped()
hva_to_pfn_remapped() calls fixup_user_fault(), which has already handled the retry gracefully. Even if "unlocked" is set to true, it means that we've got a VM_FAULT_RETRY inside fixup_user_fault(), however the page fault has already retried and we should have the pfn set correctly. No need to do that again. Signed-off-by: Peter Xu <peterx@redhat.com> Message-Id: <20200416155906.267462-1-peterx@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
