commit 168200b6d6ea0cb5765943ec5da5b8149701f36a upstream.
The variable 'traceid_list' is defined in the header file cs-etm.h, if multiple C files include cs-etm.h the compiler might complaint for multiple definition of 'traceid_list'.
To fix multiple definition error, move the definition of 'traceid_list' into cs-etm.c.
