Subject: [PATCH mm v11 36/42] kasan, arm64: expand CONFIG_KASAN checks
Date: Mon, 23 Nov 2020 21:08:00 +0100
Message-ID: <e6971e432dbd72bb897ff14134ebb7e169bdcf0c.1606161801.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1606161801.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.
