OK, I see. This is usuall inter tree mess. It didn't fly through your
tree:
commit 120f3b11ef88fc38ce1d0ff9c9a4b37860ad3140
Author: Randy Dunlap <rdunlap@infradead.org>
Date:   Mon Feb 12 17:26:20 2018 -0800

    integrity/security: fix digsig.c build error with header file
    
    security/integrity/digsig.c has build errors on some $ARCH due to a
    missing header file, so add it.
    
      security/integrity/digsig.c:146:2: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]
