Subject: [PATCH 0/2] x86/xen: don't return from xen_pv_play_dead()
Date: Fri, 25 Nov 2022 07:32:46 +0100 [thread overview]
Message-ID: <20221125063248.30256-1-jgross@suse.com> (raw)
All play_dead() functions but xen_pv_play_dead() don't return to the
caller.
Adapt xen_pv_play_dead() to behave like the other play_dead() variants.
Juergen Gross (2):
x86/xen: don't let xen_pv_play_dead() return
x86/xen: mark xen_pv_play_dead() as __noreturn
