Subject: [PATCH 4.18 040/168] tools/kvm_stat: fix python3 issues

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

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

From: Stefan Raspl <stefan.raspl@...ibm.com>

[ Upstream commit 58f33cfe73076b6497bada4f7b5bda961ed68083 ]

Python3 returns a float for a regular division - switch to a division
operator that returns an integer.
Furthermore, filters return a generator object instead of the actual
list - wrap result in yet another list, which makes it still work in
both, Python2 and 3.
