I get a compile error here:

CC arch/x86/kernel/cpu/mce/core.o
arch/x86/kernel/cpu/mce/core.c: In function ‘update_default_notifier_registration’:
arch/x86/kernel/cpu/mce/core.c:616:3: error: implicit declaration of function ‘blocking_notifier_chain_cond_register’; did you mean ‘blocking_notifier_chain_unregister’? [-Werror=implicit-function-declaration]
blocking_notifier_chain_cond_register(&x86_mce_decoder_chain,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
blocking_notifier_chain_unregister
