Bug#638863: "shpchp: Cannot reserve MMIO region" error during boot (linux 3.0)



Here's a test patch for the TCO timer issue.  That SP5100 watchdog
driver is a mess -- it gropes around at hard-coded places in I/O port
space -- so while I think this patch will fix the message, the
watchdog itself still may not work.  If you can verify that the
watchdog works, that would be great.

These are unrelated and I'm doing some other work that addresses them.

I don't know about this one.  It looks like we tried a link retrain
but it failed.  I would poke Shaohua Li <shaohua.li@intel.com> about
this since he submitted the original code for that.
