[PATCH v2 0/3] PCI: Always lift 2.5GT/s restriction in PCIe failed link retraining

[Maciej W. Rozycki]

Hi,

 I've figured out that backporting will be less intrusive if an update to 
use `->supported_speeds' is posted as a separate follow-up change.  So it 
is now 2/3 in this series, after 1/3 comprising the original patch, only 
trivially updated.  Then 3/3 moves the maximum link speed determination 
earlier on for an early exit in the PCIE_SPEED_2_5GT case; maybe unlikely, 
but essentially free now, now that we retrieve the speed anyway, and makes 
code a little simpler yet.

 Please let me know if you'd prefer me to fold 2/3 into 1/3 after all.
