a side note:
this can make it harder to read, in _the worst case_. one printk()
guaranteed that we would see a single line in the serial log/etc.
the sort of a problem with multiple printks is that printks coming
from other CPUs will split that "previously single" line.
just a notice. up to MM people to decide.
