Subject: [PATCH v2 2/2] arm64/mm: Add .rodata to kernel virtual memory boot notice
Date: Wed, 17 Feb 2016 10:41:14 -0600 [thread overview]
Message-ID: <1455727274-16328-3-git-send-email-jeremy.linton@arm.com> (raw)
In-Reply-To: <1455727274-16328-1-git-send-email-jeremy.linton@arm.com>
Now that .rodata has differing permissions from .text
display it in the mem_init banner as a seperate memory range.
