Subject: [PATCH 06/14] MIPS: memblock: Reserve kdump/crash regions in memblock
Date:   Thu, 18 Jan 2018 01:23:04 +0300
Message-Id: <20180117222312.14763-7-fancer.lancer@gmail.com>
In-Reply-To: <20180117222312.14763-1-fancer.lancer@gmail.com>
References: <20180117222312.14763-1-fancer.lancer@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Kdump/crashkernel memory regions should be reserved in the
memblock allocator so they wouldn't be occupied by any further
allocations.
