My powerpc allyesconfig build also produced this:

drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c: In function 'bnx2x_init_cyclecounter':
drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c:14613:2: error: implicit declaration of function 'CLOCKSOURCE_MASK' [-Werror=implicit-function-declaration]
  bp->cyclecounter.mask = CLOCKSOURCE_MASK(64);
  ^

So I added this patch:
