From 14a41d6b7572026cf8fc88ee72e81b6b40db2ec0 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Fri, 13 Jan 2017 14:23:49 +1030 Subject: [PATCH] powerpc/powernv: Report size of OPAL memcons log The OPAL memory console is reported to be size zero, as we do not initialise the struct attr with any size information due to the size being variable. This leads users to think that the console is empty. Instead report the maximum size.
