SubjectRe: [PATCH v5 4/5] arm64: introduce pfn_valid_region()
Hi Jia,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on linus/master]
[also build test WARNING on v4.16 next-20180329]
[cannot apply to arm64/for-next/core]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Jia-He/optimize-memblock_next_valid_pfn-and-early_pfn_valid-on-arm-and-arm64/20180402-131223
config: arm64-allmodconfig (attached as .config)
compiler: aarch64-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=arm64

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x39c4c): Section mismatch in reference from the function pfn_valid_region() to the variable .meminit.data:$d
The function pfn_valid_region() references
the variable __meminitdata $d.
This is often because pfn_valid_region lacks a __meminitdata
annotation or the annotation of $d is wrong.
