[ Upstream commit 15bfe05c8d6386f1a90e9340d15336e85e32aad6 ]
On 64-bit (e.g. powerpc64/allmodconfig):
drivers/net/ethernet/xilinx/ll_temac_main.c: In function 'temac_start_xmit_done': drivers/net/ethernet/xilinx/ll_temac_main.c:633:22: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] dev_kfree_skb_irq((struct sk_buff *)cur_p->app4); ^
cdmac_bd.app4 is u32, so it is too small to hold a kernel pointer.
Note that several other fields in struct cdmac_bd are also too small to hold physical addresses on 64-bit platforms.
