We've been getting this warning for ages:
./usr/include/linux/kexec.h:61: userspace cannot reference function or variable defined in the kernel
There is no proper fix for this file, as the declaration is meant for
user space, not for the kernel, so we should work around it the
same way that we treat the seqbuf_dump() definition.
