Please check the following :

1) It has build issue with 32bit build(gcc 7.3.1)

2) clang6 shows some crazy link errors, even though following symbol
has been not used. Looks like we need -latomic
undefined reference to `__atomic_fetch_add_8'

3) Fix check-git-log.sh issues
$./devtools/check-git-log.sh 
Wrong headline lowercase:
	event/octeontx: add multiproducer timer arm and cancel
	event/octeontx: add single producer timer arm variant
	event/octeontx: add burst mode for timer arm
