one nit-picky comment, one question.

nit-pick:
I noticed that pci_alloc_pci_controller() and pci_alloc_phb_dynamic()
are almost identical, except that one has the flag is_dynamic=1, 
and the other not.  why not merge them into one, and just pass
"is_dynamic" as a flag?

question:
I presume 'remove" is in the works?
Is part of the difficulty of implementing remove that
pci_alloc_pci_controller() calls alloc_bootmem(), which makes 
freeing these things kind-of tricky? (i.e. since pci is getting
set up before init_mem is done?)
