Subject: [RFC PATCH 2/3] pstore ram: remove the power of buffer size limitation
Date: Tue,  9 Apr 2013 22:08:16 -0500	[thread overview]
Message-ID: <1365563297-12480-2-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1365563297-12480-1-git-send-email-robherring2@gmail.com>

From: Rob Herring <rob.herring@calxeda.com>

There doesn't appear to be any reason for the overall pstore RAM buffer to
be a power of 2 size, so remove it. The individual console, ftrace and oops
buffers are still a power of 2 size.
