Subject: [PATCH] extable: skip sorting if the table is empty
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

At least on ARM no-MMU the extable is empty and so there is nothing to
sort. So add a check for the table to be empty which effectively only
changes that the misleading pr_notice is suppressed.
