Subject: [PATCH 2/5] RISC-V: Setup init_mm before parse_early_param()
Date: Mon, 7 Jan 2019 21:40:44 +0530 [thread overview]
Message-ID: <20190107161047.10516-3-anup@brainfault.org> (raw)
In-Reply-To: <20190107161047.10516-1-anup@brainfault.org>
From: Anup Patel <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.
