[Xen-devel] [x86/time] 03fa63cc96: ACPI_Error:Table[DMAR]is_not_invalidated_during_early_boot_stage(#/tbxface-#)

[kernel test robot <xiaolong.ye@xxxxxxxxx>]

FYI, we noticed the following commit:

commit: 03fa63cc96ab35592e0a7d522b8edbc1e6b02d22 ("x86/time: Initialize 
interrupt mode behind timer init")
url: 
https://github.com/0day-ci/linux/commits/Dou-Liyang/Unify-the-interrupt-delivery-mode-and-do-its-setup-in-advance/20170702-232323
base: https://git.kernel.org/cgit/linux/kernel/git/xen/tip.git linux-next

in testcase: will-it-scale
with following parameters:

        nr_task: 50%
        mode: process
        test: futex2
        cpufreq_governor: performance

test-description: Will It Scale takes a testcase and runs it from 1 through to 
n parallel copies to see if the testcase will scale. It builds both a process 
and threads based test in order to see any differences between the two.
