Subject: [PATCH v4 09/13] KVM: arm64: Introduce print_nvhe_hyp_panic helper
Date: Wed, 29 May 2024 13:12:15 +0100 [thread overview]
Message-ID: <20240529121251.1993135-10-ptosi@google.com> (raw)
In-Reply-To: <20240529121251.1993135-1-ptosi@google.com>
Add a helper to display a panic banner soon to also be used for kCFI
failures, to ensure that we remain consistent.
