> do_div is the wrong way to divide a sector_t, as it is less
> efficient when sector_t is 32-bit wide. With the upcoming
> do_div optimizations, the kernel starts warning about this:
> drivers/infiniband/ulp/iser/iser_verbs.c:1296:4: note: in expansion of macro 'do_div'
> include/asm-generic/div64.h:224:22: warning: passing argument 1 of '__div64_32' from incompatible pointer type
> This changes the code to use sector_div instead, which always
> produces optimal code.
