Subject: [PATCH v5 5/8] KVM: arm64: VHE: Mark __hyp_call_panic __noreturn
Date: Mon, 10 Jun 2024 07:32:34 +0100 [thread overview]
Message-ID: <20240610063244.2828978-6-ptosi@google.com> (raw)
In-Reply-To: <20240610063244.2828978-1-ptosi@google.com>
Given that the sole purpose of __hyp_call_panic() is to call panic(), a
__noreturn function, give it the __noreturn attribute, removing the need
for its caller to use unreachable().
