[GIT PULL] x86/sgx for 6.8

[Dave Hansen]

Hi Linus,

Please pull some x86/sgx changes for 6.8.  This time, these are
entirely confined to SGX selftests fixes.

The mini SGX enclave built by the selftests has garnered some
attention because it stands alone and does not need the sizable
infrastructure of the official SGX SDK. I think that's why folks
are suddently interested in cleaning it up.
