Subject: [PATCH 4.19 39/41] selftests/vm: fix display of page size in map_hugetlb

From: Christophe Leroy <christophe.leroy@...roup.eu>

[ Upstream commit 1ec882fc81e3177faf055877310dbdb0c68eb7db ]

The displayed size is in bytes while the text says it is in kB.

Shift it by 10 to really display kBytes.
