Subject: [PATCH 30/35] kasan, arm64: expand CONFIG_KASAN checks
Date: Fri, 14 Aug 2020 19:27:12 +0200 [thread overview]
Message-ID: <33118d2b5d458fab42db9485389b5e8159ca3b02.1597425745.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1597425745.git.andreyknvl@google.com>
Some #ifdef CONFIG_KASAN checks are only relevant for software KASAN
modes (either related to shadow memory or compiler instrumentation).
Expand those into CONFIG_KASAN_GENERIC || CONFIG_KASAN_SW_TAGS.
