 LLC

Hi Alison,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on v4.16-rc7]
[also build test WARNING on next-20180329]
[cannot apply to tip/x86/core]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

config: x86_64-allyesdebian (attached as .config)
compiler: gcc-7 (Debian 7.3.0-1) 7.3.0
reproduce:
        # save the attached .config to linux build tree
        make ARCH=x86_64 

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x9601e): Section mismatch in reference from the function set_cpu_sibling_map() to the variable .init.rodata:snc_cpu
   The function set_cpu_sibling_map() references
   the variable __initconst snc_cpu.
   This is often because set_cpu_sibling_map lacks a __initconst
   annotation or the annotation of snc_cpu is wrong.
