Subject: [PATCH 0/1] SGX self test fails

I'm just starting my learning curve on SGX, so I don't know if I've missed
some setup for the SGX device entries. After looking at arch/x86/kernel/cpu/sgx/driver.c
I see that there is no mode value for either sgx_dev_enclave or sgx_dev_provision.

With this patch I can get the SGX self test to complete:

sudo ./test_sgx
Warning: no execute permissions on device file /dev/sgx_enclave
0x0000000000000000 0x0000000000002000 0x03
0x0000000000002000 0x0000000000001000 0x05
0x0000000000003000 0x0000000000003000 0x03
SUCCESS

Is the warning even necessary ?
