SubjectRe: [PATCH V2 1/8] perf: Add PERF_SAMPLE_PHYS_ADDR
Hi Kan,

[auto build test ERROR on tip/perf/core]
[also build test ERROR on v4.4-rc8 next-20160107]
[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/kan-liang-intel-com/perf-Add-PERF_SAMPLE_PHYS_ADDR/20160108-045715
config: x86_64-randconfig-x006-01060743 (attached as .config)
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64

All errors (new ones prefixed by >>):

arch/x86/kernel/cpu/perf_event_intel_ds.c: In function 'setup_pebs_sample_data':
>> arch/x86/kernel/cpu/perf_event_intel_ds.c:1087:28: error: implicit declaration of function 'virt_to_phys' [-Werror=implicit-function-declaration]

>> arch/x86/kernel/cpu/perf_event_intel_ds.c:1098:23: error: implicit declaration of function 'page_to_phys' [-Werror=implicit-function-declaration]
data->phys_addr = page_to_phys(p) + data->addr % PAGE_SIZE;
