The init function for the RPA PCI Hotplug driver returns -ENODEV in the
case that no hotplug-capable slots are detected in the system. This is
bad, since hot-capable slots can be added after boot to a purely virtual
POWER partition. This is also bad because DLPAR I/O operations depend
on the rpaphp module.Change the rpaphp init module to return success for the case of
partitions that own no hotplug-capable slots at boot. Such slots can be
dynamically added after boot.Signed-off-by: John Rose

Minor cleanup. Move structure initializer to bottom of file,
this allows elimination of eyeball-strain-inducing forward

Minor cleanup. Add the prefix rpaphp_* to several generic-sounding routines.
Remove rpaphp_remove_slot(), which is a one-liner.Signed-off-by: Linas Vepstas

Remove general baroqueness. The function rpaphp_enable_pci_slot()
has a fairly simple logic structure, once all of the debug printk's
are removed. Its called from only one place, and that place also
has a very simple structure once he printk's are removed. Merge
the two together.Signed-off-by: Linas Vepstas

Remove general baroqueness. The function rpaphp_unconfig_pci_adapter()
is really just three lines of code, once all the dbg printks are removed.
And its called in only one place. So replace the call by the thre lines.
Also, provide proper semaphore locking in the affected function

This is a minor patch to the ppc64 PCI hotplug code; it makes the call to
rpaphp_unconfig_pci_adapter() symmetric with respect to the call to
rpaphp_config_pci_adapter(). I discussed this with John Rose, who
had provided the last round of changes for these functions; he
appearently had this patch but somehow failed to mail it out.Tested. (added/removed device).

Currently rpaphp registers the following bus types as hotplug slots:
1) Actual PCI Hotplug slots
2) Embedded/Internal PCI slots
3) PCI Host BridgesThe second and third bus types are not actually direct parents of
removable adapters. As such, the rpaphp has special case code to fake
results for attributes like power, adapter status, etc. This patch
removes types 2 and 3 from the rpaphp module.This patch also changes the DLPAR module so that slots can be
DLPAR-added/removed without having been designated as hotplug-capable.Signed-off-by: John Rose

Currently, rpaphp registers Virtual I/O slots as hotplug slots. The
only purpose of this registration is to ensure that the VIO subsystem
is notified of new VIO buses during DLPAR adds. Similarly, rpaphp
notifies the VIO subsystem when a VIO bus is DLPAR-removed. The rpaphp
module has special case code to fake results for attributes like power,
adapter status, etc.The VIO register/unregister functions could just as easily be made from
the DLPAR module. This patch moves the VIO registration calls to the
DLPAR module, and removes the VIO fluff from rpaphp altogether.Signed-off-by: John Rose

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
