[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>


[ Upstream commit 606625be47bc87b6fab0af10cd57aaa675cb9e42 ]

If "make rpm-pkg" or "make binrpm-pkg" is run with -j[jobs] option,
the following warning message is displayed.

  warning: jobserver unavailable: using -j1.  Add '+' to parent make rule.

Follow the suggestion.
