Subject: [PATCH v14 02/11] x86: kdump: make the lower bound of crash kernel reservation consistent
Date:   Sat, 30 Jan 2021 15:10:16 +0800
Message-ID: <20210130071025.65258-3-chenzhou10@huawei.com>
In-Reply-To: <20210130071025.65258-1-chenzhou10@huawei.com>

Precedence: bulk

The lower bounds of crash kernel reservation and crash kernel low
reservation are different, use the consistent value CRASH_ALIGN.
