v3: Split off the code for limiting busy_poll and busy_read into a separate
    patch for net.
    Updated patch that changed busy loop time tracking so that it uses
    "local_clock() >> 10" as we originally did.
    Tweaked "Change return type.." patch by moving declaration of "work"
    inside the loop where is was accessed and always reset to 0.
    Added "Acked-by" for patches that received acks.

Eric, I believe Alexander has addresed your concerns.  Could you please
review patches 5 and 7 and ACK if they look ok to you?

Thanks.
