Subject: linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

drivers/net/ethernet/mellanox/mlx4/en_clock.c: In function 'mlx4_en_init_timestamp':
drivers/net/ethernet/mellanox/mlx4/en_clock.c:249:2: error: implicit declaration of function 'CLOCKSOURCE_MASK' [-Werror=implicit-function-declaration]
  mdev->cycles.mask = CLOCKSOURCE_MASK(48);
  ^
drivers/net/ethernet/mellanox/mlx4/en_clock.c:257:3: error: implicit declaration of function 'clocksource_khz2mult' [-Werror=implicit-function-declaration]
   clocksource_khz2mult(1000 * dev->caps.hca_core_clock, mdev->cycles.shift);
   ^
drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c: In function 'ixgbe_ptp_start_cyclecounter':
drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c:796:2: error: implicit declaration of function 'CLOCKSOURCE_MASK' [-Werror=implicit-function-declaration]
  adapter->cc.mask = CLOCKSOURCE_MASK(64);
  ^

Presumably caused by commit 74d23cc704d1 ("time: move the
timecounter/cyclecounter code into its own file").

I added the following commit for today:
