Recent commit 175f5475fb9c5800319da4e3c4204413d7280f5c
introduced this compile warning (because vaddr is unsigned long),
so add a cast:
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c: In function ‘kiblnd_kvaddr_to_page’:
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c:532:2: warning: passing argument 1 of ‘is_vmalloc_addr’ makes pointer from integer without a cast [enabled by default]
  if (is_vmalloc_addr(vaddr)) {
  ^
In file included from drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd.h:43:0,
                 from drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c:41:
include/linux/mm.h:336:59: note: expected ‘const void *’ but argument is of type ‘long unsigned int’
 static inline int is_vmalloc_addr(const void *x)
