Subject: [PATCH-v3 13/17] staging/lustre: fix build warnning on 32bit system

Building on 32bit system, I got warnings like below:
drivers/staging/lustre/lustre/llite/../include/lprocfs_status.h:666:7: note: expected ‘long unsigned int *’ but argument is of type ‘size_t *’
 char *lprocfs_find_named_value(const char *buffer, const char *name,

drivers/staging/lustre/lustre/lov/lov_io.c: In function ‘lov_io_rw_iter_init’:
include/asm-generic/div64.h:43:28: warning: comparison of distinct pointer types lacks a cast [enabled by default]
  (void)(((typeof((n)) *)0) == ((uint64_t *)0)); \
