[PATCH v5 0/5] PCI: Patch series to support Thunderbolt without any BIOS support

[PATCH v5 0/5] PCI: Patch series to support Thunderbolt without any BIOS support

[Nicholas Johnson]

Since PATCH v4:

I have added some of the evidence and bug reports into the applicable
patches.

Users of pci=hpmemsize should not notice any changes in functionality
with this patch series when upgrading the kernel. I realised I could
make the variable to achieve this reside in pci_setup, rather than
globally.

Please let me know if anything else needs changing.

Nicholas Johnson (5):
  PCI: Consider alignment of hot-added bridges when distributing
    resources
  PCI: Modify extend_bridge_window() to set resource size directly
  PCI: Fix bug resulting in double hpmemsize being assigned to MMIO
    window
  PCI: Add pci=hpmemprefsize parameter to set MMIO_PREF size
    independently
  PCI: Cleanup block comments in setup-bus.c to match kernel style

I didn't have time to go through the actual important stuff above,

but I applied this one to pci/trivial for v5.2 to get it out of the
way for the next cycle.

I also have patches from Logan and Mika in the same area, so I'll have
to look at all of these together.
