Checking various arches, it appears the mainstream server arches (ia64, mips, ppc, s390, sparc, x86) use 'Call Trace'. This kernel tools script scans for the latter text string as well tools/testing/selftests/rcutorture/bin/parse-console.sh so it doesn't appear to be arch or vendor specific. Expecting there aren't a significant number of arm64 dump scanners matching on 'Call trace' so recommend making this change now to minimize changes to dump scanning tools for arm64 servers.
