Subject: [PATCH] hwtracing: stm: fix build error on some arches
Git-commit: 806e30873f0e74d9d41b0ef761bd4d3e55c7d510
Patch-mainline: v4.17
References: bsc#1051510

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.
