+Subject: selinux: use "grep -E" instead of "egrep"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+commit c969bb8dbaf2f3628927eae73e7c579a74cf1b6e upstream.
+
+The latest version of grep claims that egrep is now obsolete so the build
+now contains warnings that look like:
+ egrep: warning: egrep is obsolescent; using grep -E
+fix this by using "grep -E" instead.
