This is the majority of all build warnings we get on allmodconfig (both i386 and arm),
so it would be really nice to have it fixed before 4.3. For all I can tell, the
patch still applies on your branch too, but see below for the rebased version.
I also note that your branch is not part of linux-next, is that intentional?

Subject: [PATCH] i40evf: fix 32 bit build warnings
Jesse Brandeburg fixed a bug for 32-bit systems in the i40e driver
in commit 9c70d7cebfec5 ("i40e: fix 32 bit build warnings"), but the
same code still exists in the i40evf driver and causes compilation
warnings in ARM and x86 allmodconfig:
drivers/net/ethernet/intel/i40evf/i40e_common.c:445:68: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/net/ethernet/intel/i40evf/i40e_common.c:446:71: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
This applies the same fix by removing the broken code.
