After merging the net-next tree, today's linux-next build (arm allmodconfig) failed like thisi (this has actually been failing for a few days, now):
ERROR: "__bad_udelay" [drivers/net/ethernet/intel/ixgbe/ixgbe.ko] undefined!
Caused by commit

arm only allows udelay()s up to 2 milliseconds. This commit adds a 5 ms udelay in ixgbe_acquire_swfw_sync_x550em_a() in drivers/net/ethernet/intel/ixgbe/ixgbe_x550.c.
Jeff, please have your folks look into this. Probably just a simple conversion to mdelay().
This is still present, it's been breaking ARM allmodconfig builds for about two weeks now.
