Hi all,

After merging the net-next tree, today's linux-next build (powerpc
allyesconfig) failed like this:

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);
                      ^
drivers/net/ethernet/intel/fm10k/fm10k_ethtool.c: In function 'fm10k_set_ringparam':
drivers/net/ethernet/intel/fm10k/fm10k_ethtool.c:477:2: error: implicit declaration of function 'vmalloc' [-Werror=implicit-function-declaration]
  temp_ring = vmalloc(i * sizeof(struct fm10k_ring));
  ^
drivers/net/ethernet/intel/fm10k/fm10k_ethtool.c:477:12: warning: assignment makes pointer from integer without a cast
  temp_ring = vmalloc(i * sizeof(struct fm10k_ring));
            ^
drivers/net/ethernet/intel/fm10k/fm10k_ethtool.c:546:2: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]
  vfree(temp_ring);
  ^

Caused by commit 82dd0f7ee9a3 ("fm10k: Add ethtool support").  See Rule
1 in Documentation/SubmitChecklist.

I have added the following fix patch for today:
