[cip-dev] Build fail for linux-4.4.y-rc

[Chris Paterson]

Hello maintainers,

I've seen a failure this morning with our linux stable-rc build testing.

Version: 4cb9b88c651a2fff886dd64b6d797343e7ddb4dd Linux 4.4.201-rc1
Arch: arm
Config: moxa_mxc_defconfig

Pipeline: https://gitlab.com/cip-playground/linux-stable-rc-ci/pipelines/95016985
Failure: https://gitlab.com/cip-playground/linux-stable-rc-ci/pipelines/95016985/failures
Log: https://gitlab.com/cip-playground/linux-stable-rc-ci/-/jobs/346974180
Config: https://gitlab.com/cip-playground/linux-stable-rc-ci/-/jobs/346974180

All other configurations that we build were successful.

Kind regards, Chris

Thanks for heads-up!

I see warning during configuration:

HOSTLD  scripts/kconfig/conf
arch/arm/configs/moxa_mxc_defconfig:745:warning: symbol value 'm'
invalid for RTC_DRV_DS1374_WDT
#

And this suggests a way to debug it. I'll try to do that.

  MODPOST vmlinux.o
  scripts/Makefile.modpost:97: recipe for target 'vmlinux.o' failed
  WARNING: modpost: Found 1 section mismatch(es).
  To see full details build your kernel with:

  FATAL: modpost: Section mismatches detected.
  Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.

[cip-dev] Build fail for linux-4.4.y-rc

[Johnson CH Chen (陳昭勳)]

Hi Pavel,

Could you set ?RTC_DRV_DS1374_WDT=y? in moxa_mxc_defconfig and then build again?

I can build uImage and kernel modules successfully with Linux 4.4.201-rc1 in my local part.

Thanks,
Johnson

Ack with thanks!.

After using git bisect, I confirmed that the commit id
"23160bd11f183b0e77ea54befff63e5d2607155b" caused the failure,
the previous version of kernel works fine.

The below modification in "mm/page_alloc.c" seems to be the root cause.

+       /*
+        * The number of managed pages has changed due to the initialisation
+        * so the pcpu batch and high limits needs to be updated or the limits
+        * will be artificially small.
+        */
+       for_each_populated_zone(zone)
+               zone_pcp_update(zone);

Let's wait for the reply from author :-)

Apart from that, please send the MR via gitlab [1] if you want to
modify the kernel configuration.

Regression occurred [1] with the same patch in the 4.14 stable kernel, but it
failed during the boot time instead of compile time.

Thanks to Pavel's reporting, Greg has now fixed this build issue in Linux 4.4.201-rc2 (ca1d1b5f0f2a).
