    Subject[PATCH AUTOSEL 6.1 38/57] arm64: vdso: Pass (void *) to virt_to_page()
    Date
    From: Linus Walleij <linus.walleij@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.
