  Log:
  Add two workarounds for broken MP tables:
  
  	- Attempt to handle PCI devices where the interrupt is
  	  an ISA/EISA interrupt according to the mp table.
  
  	- Attempt to handle multiple IO APIC pins connected to
  	  the same PCI or ISA/EISA interrupt source.  Print a
  	  warning if this happens, since performance is suboptimal.
  	  This workaround is only used for PCI devices.
  
  With these two workarounds, the -SMP kernel is capable of running on
  my Asus P/I-P65UP5 motherboard when version 1.4 of the MP table is disabled.
