[PATCH AUTOSEL 6.1 38/57] arm64: vdso: Pass (void *) to virt_to_page()

[Sasha Levin]

From: Linus Walleij <linus.walleij at linaro.org>

[ Upstream commit b0abde80620f42d1ceb3de5e4c1a49cdd5628229 ]

Like the other calls in this function virt_to_page() expects
a pointer, not an integer.

However since many architectures implement virt_to_pfn() as
a macro, this function becomes polymorphic and accepts both a
(unsigned long) and a (void *).

Fix this up with an explicit cast.
