This is coming from our use of the do_div macro - which we wrap in an
inline function in fs/xfs/linux/xfs_linux.h
XFS has a number of 64 bit divide and modulus operations, rather than
import the compiler intrinsic from the gcc support library, we chose to
use this existing kernel macro. Unfortunately, later compilers do not
like the way we use it, and I have never figured out why. It is possible
that moving xfs_do_div and xfs_do_mod to be true functions somewhere in a .c
file rather than an inline would fix the problem, but no guarantees.
