Subject: [PATCH v2 17/19] arm64: entry: make NMI entry/exit functions static
Date: Wed, 19 May 2021 13:39:00 +0100	[thread overview]
Message-ID: <20210519123902.2452-18-mark.rutland@arm.com> (raw)
In-Reply-To: <20210519123902.2452-1-mark.rutland@arm.com>

Now that we only call arm64_enter_nmi() and arm64_exit_nmi() from within
entry-common.c, let's make these static to esnure this remains the case.
