4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Oleksandr Andrushchenko <Oleksandr_Andrushchenko@xxxxxxxx> commit 1c8a946bf3754a59cba1fc373949a8114bfe5aaa upstream. The arm64 __page_to_voff() macro takes a parameter called 'page', and also refers to 'struct page'. Thus, if the value passed in is not called 'page', we'll refer to the wrong struct name (which might not exist).
