[PATCH v3 00/13] Overhauling amx_test

From: Mingwei Zhang
Date: Tue Feb 21 2023 - 11:37:22 EST


In this version, I have integrated Aaron's changes to the amx_test. In
addition, we also integrated one fix patch for a kernel warning due to
xsave address issue.

Patch 1:
Fix a host FPU kernel warning due to missing XTILEDATA in xinit.

Patch 2-8:
Overhaul amx_test. These patches were basically from v2.

Patch 9-13:
Overhaul amx_test from Aaron. I modified the changelog a little bit.


v2 -> v3:
- integrate Aaron's 5 commits with minor changes on commit message.
- Add one fix patch for a kernel warning.

v2:
