Hi Everybody,

This series consists out of outstanding SGX selftests changes, rebased
and gathered in a single series that is more easily merged for testing
and development, and a few more changes added to expand the existing tests.

The outstanding SGX selftest changes included in this series that have already
been submitted separately are:

* An almost two year old patch fixing a benign linker warning that is still
  present today:
  https://lore.kernel.org/linux-sgx/20191017030340.18301-2-sean.j.christopherson@intel.com/
  The original patch is added intact and not all email addresses
  within are valid.

* Latest (v4) of Jarkko Sakkinen's series to add an oversubscription test:
  https://lore.kernel.org/linux-sgx/20210809093127.76264-1-jarkko@kernel.org/

* Latest (v2) of Jarkko Sakkinen's patch that provides provide per-op
  parameter structs for the test enclave:
  https://lore.kernel.org/linux-sgx/20210812224645.90280-1-jarkko@kernel.org/

The reason why most of these patches are outstanding is that they depend
on a kernel change that is still under discussion. Decision to wait in:
https://lore.kernel.org/linux-sgx/f8674dac5579a8a424de1565f7ffa2b5bf2f8e36.camel@kernel.org/
The original patch for this kernel dependency continues to be included in
this series as a placeholder until the ongoing discussions are concluded.

The new changes introduced in this series builds on Jarkko's outstanding
SGX selftest changes and adds new tests for page permissions, exception
handling, and thread entry.
