Subject: [PATCH v3 3/5] arm64: Kconfig: support CONFIG_KASAN_VMALLOC
Date: Sat, 6 Feb 2021 16:35:50 +0800	[thread overview]
Message-ID: <20210206083552.24394-4-lecopzer.chen@mediatek.com> (raw)
In-Reply-To: <20210206083552.24394-1-lecopzer.chen@mediatek.com>

Now we can backed shadow memory in vmalloc area,
thus make KASAN_VMALLOC selectable.
