From af48c7b08de4b811d3d974e65e362b86ce8c4a34 Mon Sep 17 00:00:00 2001
From: Bruce Ashfield <bruce.ashfield@windriver.com>

Subject: [PATCH] compaction: fix mm_compaction_isolate_template build
linux-stable integrated the 3.16 commit f8c9301fa5a2a [mm/compaction: do
not count migratepages when unnecessary] with the 3.14.25 update.
So we have to update the lttng-module linux version codes to use the
new definition in builds greater than 3.14.24 or 3.16.
