History
Nate Lawson 298e3d15d7 Work around non-compliant BIOS PCI link devices. Some systems have the 
following behavior:

* Link devices return invalid status (_STA) values.  The results are very
  unreliable -- sometimes never present.  Just ignore the status and pick
  the best configuration from _PRS.

* Link devices return invalid current settings (_CRS).  Even after setting
  the link value, many systems still return a different setting for _CRS.
  When setting an IRQ, don't bother to check _CRS to see if we succeeded.
  Note that we still check _CRS before routing and this should be addressed
  as well.

Since this is a sensitive area, leave the old behavior accessible via
uncommenting the define for ACPI_OLD_PCI_LINK at the top of the file.  Once
this has been thoroughly tested, this option and the code it covers will
be removed.

Thanks to Len Brown at Intel for informing us of these issues as he worked
around them in Linux.
