SubjectRe: [PATCH v4 2/4] Always running timer correlated clocksource
Hi Christopher,

[auto build test ERROR on net/master -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

url: https://github.com/0day-ci/linux/commits/Christopher-S-Hall/Patchset-enabling-hardware-based-cross-timestamps-for-next-gen-Intel-platforms/20151013-095135
config: x86_64-randconfig-x015-10130227 (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/tsc.c:1098:18: error: 'art_to_tsc_denominator' undeclared (first use in this function)
res = (cycles / art_to_tsc_denominator) * art_to_tsc_numerator;
^
arch/x86/kernel/tsc.c:1098:18: note: each undeclared identifier is reported only once for each function it appears in
>> arch/x86/kernel/tsc.c:1098:44: error: 'art_to_tsc_numerator' undeclared (first use in this function)
res = (cycles / art_to_tsc_denominator) * art_to_tsc_numerator;
