SubjectRe: [PATCH 2/6] drivers: perf: hisi: Add support for HiSilicon SoC uncore PMU driver
Hi Shaokun,

[auto build test ERROR on next-20170619]
[also build test ERROR on v4.12-rc7]
[cannot apply to linus/master linux/master arm64/for-next/core v4.12-rc6 v4.12-rc5 v4.12-rc4]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Shaokun-Zhang/Add-HiSilicon-SoC-uncore-Performance-Monitoring-Unit-driver/20170628-070841
config: x86_64-allmodconfig (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901

# save the attached .config to linux build tree
make ARCH=x86_64
