Subject: [PATCH v11 0/4] PCI: Patch series to assist Thunderbolt without any
 BIOS support

Since last time:

No significant changes. Re-post to get attention and to level out the 
patch version numbers (some in the series had been incremented and 
others stayed the same).

Change name of patch series. In hindsight, this will not "support" 
Thunderbolt with no BIOS. It helps, though - it makes it usable.

Something I have not gotten to work is sleep. Suspending tends to crash 
the computer if Thunderbolt devices are attached at the time (without 
the BIOS support). I have tried to modify the Thunderbolt driver to hit 
up the pcie2tbt mailbox on Titan Ridge, but to no avail. There might be 
a PERST_N in GPIO which needs asserting - which is difficult.

Nicholas Johnson (4):
  PCI: Consider alignment of hot-added bridges when distributing
    available resources
  PCI: In extend_bridge_window() change available to new_size
  PCI: Change extend_bridge_window() to set resource size directly
  PCI: Allow extend_bridge_window() to shrink resource if necessary
