Subject: [PATCH 06/14] MIPS: memblock: Reserve kdump/crash regions in memblock
Date: Thu, 18 Jan 2018 01:23:04 +0300 [thread overview]
Message-ID: <20180117222312.14763-7-fancer.lancer@gmail.com> (raw)
In-Reply-To: <20180117222312.14763-1-fancer.lancer@gmail.com>
Kdump/crashkernel memory regions should be reserved in the
memblock allocator so they wouldn't be occupied by any further
allocations.
