Subject: [PATCH 3/4] arm64: mm: drop unused __pa(__idmap_text_start)
Date: Tue, 18 May 2021 18:14:04 +0800	[thread overview]
Message-ID: <20210518101405.1048860-4-aisheng.dong@nxp.com> (raw)
In-Reply-To: <20210518101405.1048860-1-aisheng.dong@nxp.com>

x5 is not used in the following map_memory. Instead,
__pa(__idmap_text_start) is stored in x3 which is used later.
