The definitions for the patch sites etc. don't belong in
asm-prototypes.h, they are not EXPORT'ed asm symbols.
Move them into sections.h which is traditionally used for asm symbols.

Yeah, the kernel is complicated for them in different ways, so I

Fair enough. Exactly I have that same concern. But

Creating or filling pci-OF-bus-map property in the device-tree is
deprecated since May 2006 [1]. Allow to disable filling this property by
unsetting config option CONFIG_PPC_PCI_OF_BUS_MAP_FILL for remaining chrp
and powermac code.
Disabling of pci-OF-bus-map property allows to enable new option
It makes sense to enable CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT by default
(when possible by dependencies) to take advantages of all 256 PCI buses on
each PCI domain, like it is already on all other kernel architectures.

I don't think this is correct; read_count can have spurious
