    Pull x86 SGX updates from Dave Hansen:
     "A set of x86/sgx changes focused on implementing the "SGX2" features,
      plus a minor cleanup:
    
       - SGX2 ISA support which makes enclave memory management much more
         dynamic. For instance, enclaves can now change enclave page
         permissions on the fly.
    
       - Removal of an unused structure member"
