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

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

From: Punit Agrawal <punit.agra...@arm.com>

Commit 45ee9d5e97a4 ("KVM: arm/arm64: Check pagesize when allocating a
hugepage at Stage 2") lost the check for PMD_SIZE during the backport
to 4.9.

Fix this by correcting the condition to detect hugepages during stage
2 allocation.

at Stage 2")
