Subject: Re: [PATCH 2/6] arm_pmu: Change API to support 64bit counter values

Hi Suzuki,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on tip/perf/core]
[also build test ERROR on v4.17-rc6 next-20180517]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
