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

From: Nadav Amit <namit@vmware.com>
commit 14b1fcc62043729d12e8ae00f8297ab2ffe9fa91 upstream.
The comment is confusing since the path is taken when CONFIG_PAGE_TABLE_ISOLATION=y is disabled (while the comment says it is not taken).
