 Section mismatch in reference from the function can_free_region() to the

commit: 3bce64f019a801f526cc38523c77ffda4e846155 [35/62] x86/boot/e820: Rename e820_any_mapped()/e820_all_mapped() to e820__mapped_any()/e820__mapped_all()
config: x86_64-randconfig-in0-03190222 (attached as .config)
compiler: gcc-4.6 (Debian 4.6.4-7) 4.6.4
reproduce:
        git checkout 3bce64f019a801f526cc38523c77ffda4e846155
        # save the attached .config to linux build tree
        make ARCH=x86_64 

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text.unlikely+0x2f69): Section mismatch in reference from the function can_free_region() to the function .init.text:e820__mapped_all()
   The function can_free_region() references
   the function __init e820__mapped_all().
   This is often because can_free_region lacks a __init
   annotation or the annotation of e820__mapped_all is wrong.
