Subject: [PATCH v3 0/2] x86: AMX enabling example with new constants

Hi all,

Here are the changes from the last version [1]:
* Add AMX feature numbers as ABI constants (Tony Luck).
* Revise sentences in the documentation (Bagas Sanjaya).
* Adjust the code example.

Thank you Tony and Bagas for the feedback.

=== Cover Letter ===

With the AMX support in the mainline, recently I heard some folks had a
hard time understanding the AMX enabling process. A code example is
expected to clarify the steps. Along with that, add a couple of ABI
constants useful for the feature enabling.

The arch_prctl(2) manual page [2] is missing these new options. Perhaps,
the man-page update follows up along with this.

These changes can be found in the repo:
  git://github.com/intel/amx-linux.git doc

And the compiled preview is available here:

Thanks,
Chang
