I think this patch (commit 12a78d43de76, also posted for 3.18, 4.4, and 4.9) 
also needs to update these:
    tools/objtool/arch/x86/lib/x86-opcode-map.txt
    tools/perf/util/intel-pt-decoder/x86-opcode-map.txt

to avoid warnings like:

Warning: synced file at 'tools/objtool/arch/x86/lib/x86-opcode-map.txt' differs from latest kernel version at 'arch/x86/lib/x86-opcode-map.txt'
