Extend the enclave to have two operations: ENCL_OP_PUT and ENCL_OP_GET. ENCL_OP_PUT stores value inside the enclave address space and ENCL_OP_GET reads it. The internal buffer can be later extended to be variable size, and allow reclaimer tests. Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
