Thank you, Heiko!

Whether this wording sounds better?

s390/irq,nmi: include <asm/vtime.h> header directly                         

update_timer_sys() and update_timer_mcck() are inlines used for             
CPU time accounting from the interrupt and machine-check handlers.          
These routines are specific to s390 architecture, but included              
via <linux/vtime.h> header implicitly. Avoid the extra loop and             
include <asm/vtime.h> header directly.
