    PnP: move pnpacpi/pnpbios_init to after PCI init · ed458df4
    Linus Torvalds authored
    We already did that a long time ago for pnp_system_init, but
    pnpacpi_init and pnpbios_init remained as subsys_initcalls, and get
    linked into the kernel before the arch-specific routines that finalize
    the PCI resources (pci_subsys_init).
    
    This means that the PnP routines would either register their resources
    before the PCI layer could, or would be unable to check whether a PCI
    resource had already been registered.  Both are problematic.
    
    I wanted to do this before 2.6.27, but every time we change something
    like this, something breaks.  That said, _every_ single time we trust
    some firmware (like PnP tables) more than we trust the hardware itself
    (like PCI probing), the problems have been worse.
