This patch series is to fix cs-etm tracing packet handling: Patch 0001 is to add invalid address macro for readable coding; Patch 0002 is one minor fixing to return error code for instruction sample failure; Patches 0003~0006 are fixing patches for start tracing packet and CS_ETM_TRACE_ON packet. This patch series is applied on acme tree [1] on branch perf/core with latest commit: e238cf2e3d2e ("perf intel-pt: Fix packet decoding of CYC packets"). Also applied successfully this patch series on Linus tree on 4.18-rc1.
