Subject: [PATCH v2 11/15] powerpc: convert to setup_initial_init_mm()
Date: Fri, 4 Jun 2021 15:06:29 +0800	[thread overview]
Message-ID: <20210604070633.32363-12-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20210604070633.32363-1-wangkefeng.wang@huawei.com>

Use setup_initial_init_mm() helper to simplify code.

Note klimit is (unsigned long) _end, with new helper,
will use _end directly.
