Subject: [PATCH v2 4/4] riscv: switch over to generic free_initmem()
Date: Mon, 18 Feb 2019 20:41:25 +0200	[thread overview]
Message-ID: <1550515285-17446-5-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1550515285-17446-1-git-send-email-rppt@linux.ibm.com>

The riscv version of free_initmem() differs from the generic one only in
that it sets the freed memory to zero.

Make ricsv use the generic version and poison the freed memory.
