Subject: [PATCH v2 RESEND 4/5] s390/irq,nmi: include <asm/vtime.h> header directly
Date: Thu, 22 Feb 2024 15:33:40 +0100	[thread overview]
Message-ID: <98c78ea88bed855f06bd59ee44ab1ce6e1e7d52e.1708612016.git.agordeev@linux.ibm.com> (raw)
In-Reply-To: <cover.1708612016.git.agordeev@linux.ibm.com>

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.

Acked-by: Heiko Carstens <hca@linux.ibm.com>
