Subject: [PATCH 4.9 09/97] arm64: mm: Change page table pointer name in p[md]_set_huge()

From: Ben Hutchings <ben.hutchings@...ethink.co.uk>

This is preparation for the following backported fixes.  It was done
upstream as part of commit 20a004e7b017 "arm64: mm: Use
READ_ONCE/WRITE_ONCE when accessing page tables", the rest of which
does not seem suitable for stable.
