Hi Alison,

Thank you for the patch! Perhaps something to improve:

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.
