Hi all,

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

drivers/net/ethernet/freescale/enetc/enetc.c: In function 'enetc_alloc_txbdr':
drivers/net/ethernet/freescale/enetc/enetc.c:685:17: error: implicit declaration of function 'vzalloc'; did you mean 'kzalloc'? [-Werror=implicit-function-declaration]
  txr->tx_swbd = vzalloc(txr->bd_count * sizeof(struct enetc_tx_swbd));
                 ^~~~~~~
