Subject: [PATCH 03/15] arm64: kvm: Fix symbol dependency in __hyp_call_panic_nvhe
Date: Thu, 30 Apr 2020 15:48:19 +0100
Message-ID: <20200430144831.59194-4-dbrazdil@google.com> (raw)
In-Reply-To: <20200430144831.59194-1-dbrazdil@google.com>

__hyp_call_panic_nvhe contains inline assembly which did not declare
its dependency on the __hyp_panic_string symbol.
