Thanks for reporting this. The error is caused by patch 3:
[PATCH 3/8] include/linux/kexec.h: move down crash_core.h including

In this lkp's config, CONFIG_CRASH_CORE=y and CONFIG_KEXEC_CORE=n, the
moving down of crash_core.h including will triger the error. I will
think of another way to fix this.
