I see what this is doing: getting rid of the implicit include of asm/vtime.h most likely via linux/hardirq.h, but that's not very obvious. Anyway: Acked-by: Heiko Carstens <hca@linux.ibm.com>

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.
