Since they are in different sections, this generates a warning. make CONFIG_DEBUG_SECTION_MISMATCH=y ... WARNING: arch/x86/crypto/aesni-intel.o(.init.text+0x12b): Section mismatch in reference from the function init_module() to the function .exit.text:crypto_fpu_exit() The function __init init_module() references a function __exit crypto_fpu_exit(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of crypto_fpu_exit() so it may be used outside an exit section. Fix the warning by removing the __exit annotation.
