Subject: Re: [PATCH v17 08/15] clocksource/drivers/arm_arch_timer: move
 arch_timer_needs_of_probing into DT init call

Hi Fu,

[auto build test ERROR on pm/linux-next]
[also build test ERROR on v4.9-rc6]
[cannot apply to tip/timers/core next-20161125]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

base:   https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git linux-next
config: arm64-defconfig (attached as .config)
compiler: aarch64-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=arm64 

Note: the linux-review/fu-wei-linaro-org/acpi-clocksource-add-GTDT-driver-and-GTDT-support-in-arm_arch_timer/20161125-171111 HEAD 498f1f2503da21841b0e7679ddbdb86a40451bdb builds fine.
      It only hurts bisectibility.
