net: openvswitch: use div_u64() for 64-by-32 divisions
Compile the kernel for arm 32 platform, the build warning found. To fix that, should use div_u64() for divisions. | net/openvswitch/meter.c:396: undefined reference to `__udivdi3' [add more commit msg, change reported tag, and use div_u64 instead of do_div by Tonghao] Fixes: e57358873bb5d6ca ("net: openvswitch: use u64 for meter bucket") Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Tonghao Zhang <xiangxia.m.yue@gmail.com> Tested-by: Tonghao Zhang <xiangxia.m.yue@gmail.com> Signed-off-by: David S.
