Subject: [PATCH 1/2] xen: make HYPERVISOR_get_debugreg() always_inline
Date: Thu, 25 Nov 2021 10:20:55 +0100 [thread overview]
Message-ID: <20211125092056.24758-2-jgross@suse.com> (raw)
In-Reply-To: <20211125092056.24758-1-jgross@suse.com>
HYPERVISOR_get_debugreg() is being called from noinstr code, so it
should be attributed "always_inline".
Fixes: f4afb713e5c3a4419ba ("x86/xen: Make get_debugreg() noinstr")
Reported-by: kernel test robot <lkp@intel.com>
