Thanks for the report!
This is resolved in mainline now with commit 45be2ad007a9 ("x86/vdso: Conditionally export __vdso_sgx_enter_enclave()"). I was going to request stable backports once it was a little calmer but if people are hitting this now, I guess now is as good a time as ever :) I believe it should backport cleanly to 5.15+, which is where it is needed.
Cheers, Nathan
