[PATCH 3.18 064/150] KVM: s390: Fix size of monitor-class number field
From: Greg Kroah-Hartman
Date: Wed Jan 14 2015 - 03:36:33 EST
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Huth <thuth@xxxxxxxxxxxxxxxxxx>
commit a36c5393266222129ce6f622e3bc3fb5463f290c upstream.
The monitor-class number field is only 16 bits, so we have to use
a u16 pointer to access it.
