Subject: [PATCH v3 2/6] RISC-V: Setup init_mm before parse_early_param()
Date: Tue, 12 Feb 2019 14:00:21 +0000
Message-ID: <20190212135942.105008-3-anup.patel@wdc.com> (raw)
In-Reply-To: <20190212135942.105008-1-anup.patel@wdc.com>

We should setup init_mm before doing parse_early_param() in setup_arch()
to be consistent with setup_arch() of other architectures such as x86,
ARM, and ARM64.
