config: x86_64-rhel (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+0x3b320a): Section mismatch in reference from the function ima_match_policy() to the variable .init.data:init_keyring
   The function ima_match_policy() references
   the variable __initdata init_keyring.
   This is often because ima_match_policy lacks a __initdata
   annotation or the annotation of init_keyring is wrong.
