[RFC PATCH 2/3] pstore ram: remove the power of buffer size limitation

From: Rob Herring
Date: Tue Apr 09 2013 - 23:08:48 EST


From: Rob Herring <rob.herring@xxxxxxxxxxx>

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.
