Subject: Warning with next-20210121 on s390
Date: Thu, 21 Jan 2021 15:39:25 +0100	[thread overview]
Message-ID: <20210121143926.21440-1-svens@linux.ibm.com> (raw)

there's a warning with linux-next on s390:

[   33.893818] systemd-xdg-autostart-generator[544]: Not generating service for XDG autostart app-at\x2dspi\x2ddbus\x2dbus-autostart.service, startup phases are not supported. 
[   54.613344] ------------[ cut here ]------------ 
[   54.613702] Late current task rescheduling may be lost

This is because of a non-obvious merge conflict between 56e62a737028
("s390: convert to generic entry") and 845f44e8ef28 ("sched: Report local
wake up on resched blind zone within idle loop"). Can you include the attached patch
into linux-next?

Thanks,
Sven
