Subject: [PATCH v4 5/6] MIPS: kexec: Relax memory restriction
Date: Wed, 5 Sep 2018 08:59:08 -0700 [thread overview]
Message-ID: <20180905155909.30454-6-dzhu@wavecomp.com> (raw)
In-Reply-To: <20180905155909.30454-1-dzhu@wavecomp.com>
We can rely on the system kernel and the dump capture kernel themselves in
memory usage.
Being restrictive with 512MB limit may cause kexec tool failure on some
platforms.
