Jarkko Sakkinen	6a7171b8a0	selftests/sgx: Rename 'eenter' and 'sgx_call_vdso' ... Rename symbols for better clarity: * 'eenter' might be confused for directly calling ENCLU[EENTER]. It does not. It calls into the VDSO, which actually has the EENTER instruction. * 'sgx_call_vdso' is *only* used for entering the enclave. It's not some generic SGX call into the VDSO.

Jarkko Sakkinen	2adcba79e6	selftests/x86: Add a selftest for SGX ... Add a selftest for SGX. It is a trivial test where a simple enclave copies one 64-bit word of memory between two memory locations, but ensures that all SGX hardware and software infrastructure is functioning.
