Subject: [PATCH v2 2/4] arm64: kasan: abstract _text and _end to KERNEL_START/END
Date: Sat,  9 Jan 2021 18:32:50 +0800	[thread overview]
Message-ID: <20210109103252.812517-3-lecopzer@gmail.com> (raw)
In-Reply-To: <20210109103252.812517-1-lecopzer@gmail.com>

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