Subject: [PATCH 4.4 30/37] hwtracing: stm: fix build error on some arches

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

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

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

commit 806e30873f0e74d9d41b0ef761bd4d3e55c7d510 upstream.

Commit b5e2ced9bf81 ("stm class: Use vmalloc for the master map") caused
a build error on some arches as vmalloc.h was not explicitly included.

Fix that by adding it to the list of includes.
