  Log:
   	aic7xxx.c:
  		Correct an off by one in our critical section handling.
  		SEQADDR always reads the next instruction to execute,
  		so we must subtract one from its value before making
  		comparisons with entries in the critical section table.
  
  		Print a few additional registers whenever we dump
  		card state.
  
  		Show the SCB_CONTROL and SCB_TAG values for all pending
  		SCBs in card SCB ram when dumping card state.
  
  	aic7xxx.seq:
  		Fix a bug introduced while optimizing the SDPTR path.
  		We would ack the SDPTR message twice on Ultra2 or better
  		chips if it occurred after all data had been transferred
  		for a transaction.
  
  		Change our workaround for the PCI2.1 retry bug on some
  		chips.  Although the previous workaround was logically
  		correct, its faster method of draining the FIFO seemed
  		to occassionally confuse the FIFO state.  We now drain
  		the FIFO at half the speed which avoids the problem.
  
  	aic7xxx_pci.c:
  		Chips with the PCI 2.1 retry bug can't handle a 16byte
  		cachesize.  If the cachesize is set to 16bytes, drop
  		it to 0.
