 * function (or the same function with different arguments) after a
 * function exited with 1 as return value.
 *
 * As all of the functions below could be called from interrupt context,
 * we have to spin_lock_irqsave around the do { ret = bla(); } while(ret==1)
 * block.  Really bad latency there.
 *
 * Probably the best solution to all this is have the generic code manage
 * the screen buffer and a kernel thread to call STI occasionally.
 *
 * Luckily, the frame buffer guys have the same problem so we can just wait
 * for them to fix it and steal their solution.   prumpf
