SubjectRe: [PATCH v5 06/23] powerpc32: refactor x_mapped_by_bats() and x_mapped_by_tlbcam() together
Hi Christophe,

[auto build test ERROR on powerpc/next]
[also build test ERROR on v4.5-rc2 next-20160205]
[if your patch is applied to the wrong git tree, please drop us a note to help improving the system]

url: https://github.com/0day-ci/linux/commits/Christophe-Leroy/powerpc-8xx-Use-large-pages-for-RAM-and-IMMR-and-other-improvments/20160204-071322
base: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next
config: powerpc-ppc64e_defconfig (attached as .config)
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=powerpc
