3.2.56-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Helge Deller <del...@gmx.de>
commit 3873d064b8538686bbbd4b858dc8a07db1f7f43a upstream.
When compiling a 32bit kernel with CONFIG_LBDAF=n the compiler complains like
shown below. Fix this warning by instead using sector_div() which is provided
by the kernel.h header file.
fs/nfs/blocklayout/extents.c: In function ‘normalize’:
include/asm-generic/div64.h:43:28: warning: comparison of distinct pointer
types lacks a cast [enabled by default]
fs/nfs/blocklayout/extents.c:47:13: note: in expansion of macro ‘do_div’
nfs/blocklayout/extents.c:47:2: warning: right shift count >= width of type
[enabled by default]
fs/nfs/blocklayout/extents.c:47:2: warning: passing argument 1 of ‘__div64_32’
from incompatible pointer type [enabled by default]
include/asm-generic/div64.h:35:17: note: expected ‘uint64_t *’ but argument is
of type ‘sector_t *’
extern uint32_t __div64_32(uint64_t *dividend, uint32_t divisor);
