[wuzhangjin@gmail.com]

From: Wu Zhangjin <wuzj@lemote.com>

mm/page_alloc.c:1760: warning: passing argument 1 of ‘virt_to_phys’
makes pointer from integer without a cast

mm/page_alloc.c:1760
        ...
        unsigned long addr;
        ...
        split_page(virt_to_page(addr), order);

        #define virt_to_page(kaddr) pfn_to_page(PFN_DOWN(virt_to_phys(kaddr)))
        #define virt_addr_valid(kaddr)  pfn_valid(PFN_DOWN(virt_to_phys(kaddr)))
