SubjectRe: [PATCH 3/4] arch, x86, tsc: inform TSC deadline clockevent device about recalibration
Hi,

[auto build test ERROR on tip/timers/core]
[also build test ERROR on v4.7-rc6 next-20160708]
[cannot apply to tip/x86/core]
[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/Nicolai-Stange/avoid-double-timer-interrupt-with-nohz-and-Intel-TSC/20160710-202914
config: i386-tinyconfig (attached as .config)
compiler: gcc-6 (Debian 6.1.1-1) 6.1.1 20160430
reproduce:
# save the attached .config to linux build tree
make ARCH=i386

All errors (new ones prefixed by >>):
