Reported-by: kernel test robot <lkp@intel.com>

All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0x22878): Section mismatch in reference from the function alloc_init_cont_pmd() to the variable .init.data:crash_mem_map
The function alloc_init_cont_pmd() references
the variable __initdata crash_mem_map.
This is often because alloc_init_cont_pmd lacks a __initdata
annotation or the annotation of crash_mem_map is wrong.
