Subject: [PATCH 2/3] arm64: kasan: abstract _text and _end to KERNEL_START/END
Date: Mon,  4 Jan 2021 01:11:36 +0800	[thread overview]
Message-ID: <20210103171137.153834-3-lecopzer@gmail.com> (raw)
In-Reply-To: <20210103171137.153834-1-lecopzer@gmail.com>

Arm64 provide defined macro for KERNEL_START and KERNEL_END,
thus replace by the abstration instead of using _text and _end directly.
