SubjectRe: [PATCH] perf/x86/amd/power: Add AMD accumulated power reporting
Hi Borislav,

[auto build test ERROR on tip/x86/core]
[also build test ERROR on v4.5-rc1 next-20160128]
[if your patch is applied to the wrong git tree, please drop us a note to help improving the system]

url: https://github.com/0day-ci/linux/commits/Borislav-Petkov/perf-x86-amd-power-Add-AMD-accumulated-power-reporting/20160128-170527
config: i386-randconfig-a0-01271607 (attached as .config)
reproduce:
# save the attached .config to linux build tree
make ARCH=i386
