[RFC PATCH v1 3/3] LSM/x86/sgx: Call new LSM hooks from SGX subsystem

There are three places LSM hooks are called from within the SGX subsystem. The first place is to invoke security_file_mprotect() in sgx_mmap() to validate requested protection. Given the architecture of SGX subsystem, all enclaves look like file mappings of /dev/sgx/enclave device file, meaning th
