  PCI: Remove MRRS modification from MPS setting code

  Modifying the Maximum Read Request Size to 0 (value of 128Bytes) has
  massive negative ramifications on some devices.  Without knowing which
  devices have this issue, do not modify from the default value when
  walking the PCI-E bus in pcie_bus_safe mode.  Also, make pcie_bus_safe
  the default procedure.

Hello,

I found this commit here:
http://permalink.gmane.org/gmane.linux.kernel.pci/11700

This is an early version of the patch.  This is the patch that you want:
https://github.com/torvalds/linux/commit/ed2888e906b56769b4ffabb9c577190438aa68b8

It appears that this patch didn't make it to lkml or linux-pci list
due to kernel.org DNS being down when it was sent.

Thanks,
Jon

I need to learn how to use git at some point, can you please provide plain
text patches so I can apply them and reboot?

Justin.
