[ 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.
