As the unfortunate author of both of the reverted patches and author
of the pci=norom patch I can confirm that Jiri is correct.  The issues
that the patches addressed (with some unintended side effects caused
by the reverted attempts) were PCI resource allocation failures observed
during PCI hotplug.  We were not seeing or trying to address boot-time
PCI resource allocation failures or hangs.
