Subject: [PATCH 06/11] net: ethernet: xilinx: Mark XILINX_LL_TEMAC broken on
 64-bit
Patch-mainline: v4.15-rc2
Git-commit: 15bfe05c8d6386f1a90e9340d15336e85e32aad6
References: git-fixes

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.
