v1 --> v2: 1. Drop part2. Now, we only use the SMMUv3 hardware feature STE.config=0b000 (Report abort to device, no event recorded) to suppress the event messages caused by the unexpected devices. 2. rewrite the patch description.
v1: This patch series include two parts: 1. Patch1-2 use dummy STE tables with "ste abort" hardware feature to abort unexpected devices accessing. For more details, see the description in patch 2. 2. If the "ste abort" feature is not support, force the unexpected devices in the secondary kernel to use the memory maps which it used in the first kernel. For more details, see patch 5.
