ARC: init: Pass a pointer to virt_to_pfn() in init
Functions that work on a pointer to virtual memory such as virt_to_pfn() and users of that function such as virt_to_page() are supposed to pass a pointer to virtual memory, ideally a (void *) or other pointer. 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 up the offending call in arch/arc with an explicit cast. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
