Subject: [PATCH -next 2/2] crypto: x86: kmsan: disable accelerated configs in KMSAN builds
Date: Fri, 9 Sep 2022 11:58:11 +0200 [thread overview]
Message-ID: <20220909095811.2166073-2-glider@google.com> (raw)
In-Reply-To: <20220909095811.2166073-1-glider@google.com>
KMSAN is unable to understand when initialized values come from assembly.
Disable accelerated configs in KMSAN builds to prevent false positive
reports.
