commit: f09c1acfaa4b198694a31ba3e454c7d17c4fa680 [46/48] rcu: Add consistency checks for uses of segmented callback lists
config: xtensa-audio_kc705_defconfig (attached as .config)
compiler: xtensa-test_kc705_hifi-elf-gcc (crosstool-NG crosstool-ng-1.22.0-134-ge1d494a) 5.3.0
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
        git checkout f09c1acfaa4b198694a31ba3e454c7d17c4fa680
        # save the attached .config to linux build tree
        make.cross ARCH=xtensa 

Note: the rcu/rcu/dev HEAD b3b0ab10a4ccb03ecb7cb3c3f39294e40640cabb builds fine.
      It only hurts bisectibility.
