Hi Denys,

[auto build test WARNING on tip/auto-latest]
[also build test WARNING on v4.8-rc6 next-20160916]
[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]
[Suggest to use git(>=2.9.0) format-patch --base=<commit> (or --base=auto for convenience) to record what (public, well-known) commit your patch series was built on]
[Check https://git-scm.com/docs/git-format-patch for more information]

url:    https://github.com/0day-ci/linux/commits/Denys-Vlasenko/x86-e820-Mark-some-static-functions-__init/20160918-054310
config: i386-randconfig-i1-09171826 (attached as .config)
compiler: gcc-4.8 (Debian 4.8.4-1) 4.8.4
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x37714): Section mismatch in reference from the function free_initmem() to the function .init.text:e820_reallocate_tables()
   The function free_initmem() references
   the function __init e820_reallocate_tables().
   This is often because free_initmem lacks a __init
   annotation or the annotation of e820_reallocate_tables is wrong.
