Subject: arm64: mm: avoid name clash in __page_to_voff()
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).
