powerpc/eeh: Make early EEH init pseries specific The eeh_ops->probe() function is called from two different contexts: 1. On pseries, where we set EEH_PROBE_MODE_DEVTREE, it's called in eeh_add_device_early() which is supposed to run before we create a pci_dev. 2. On PowerNV, where we set EEH_PROBE_MODE_DEV, it's called in eeh_device_add_late() which is supposed to run *after* the pci_dev is created. The "early" probe is required because PAPR requires that we perform an RTAS call to enable EEH support on a device before we start interacting with it via config space or MMIO. This requirement doesn't exist on PowerNV and shoehorning two completely separate initialisation paths into a common interface just results in a convoluted code everywhere. Additionally the early probe requires the probe function to take an pci_dn rather than a pci_dev argument. We'd like to make pci_dn a pseries specific data structure since there's no real requirement for them on PowerNV. To help both goals move the early probe into the pseries containment zone so the platform depedence is more explicit.

pci/of: Match PCI devices to OF nodes dynamically powerpc has two different ways of matching PCI devices to their corresponding OF node (if any) for historical reasons. The ppc64 one does a scan looking for matching bus/dev/fn, while the ppc32 one does a scan looking only for matching dev/fn on each level in order to be agnostic to busses being renumbered (which Linux does on some platforms). This removes both and instead moves the matching code to the PCI core itself. It's the most logical place to do it: when a pci_dev is created, we know the parent and thus can do a single level scan for the matching device_node (if any). The benefit is that all archs now get the matching for free. There's one hook the arch might want to provide to match a PHB bus to its device node. A default weak implementation is provided that looks for the parent device device node, but it's not entirely reliable on powerpc for various reasons so powerpc provides its own.

[POWERPC] Rewrite IO allocation & mapping on powerpc64 This rewrites pretty much from scratch the handling of MMIO and PIO space allocations on powerpc64. The main goals are: - Get rid of imalloc and use more common code where possible - Simplify the current mess so that PIO space is allocated and mapped in a single place for PCI bridges - Handle allocation constraints of PIO for all bridges including hot plugged ones within the 2GB space reserved for IO ports, so that devices on hotplugged busses will now work with drivers that assume IO ports fit in an int. - Cleanup and separate tracking of the ISA space in the reserved low 64K of IO space. No ISA -> Nothing mapped there. I booted a cell blade with IDE on PIO and MMIO and a dual G5 so far, that's it :-) With this patch, all allocations are done using the code in mm/vmalloc.c, though we use the low level __get_vm_area with explicit start/stop constraints in order to manage separate areas for vmalloc/vmap, ioremap, and PCI IOs. This greatly simplifies a lot of things, as you can see in the diffstat of that patch :-) A new pair of functions pcibios_map/unmap_io_space() now replace all of the previous code that used to manipulate PCI IOs space. The allocation is done at mapping time, which is now called from scan_phb's, just before the devices are probed (instead of after, which is by itself a bug fix). The only other caller is the PCI hotplug code for hot adding PCI-PCI bridges (slots). imalloc is gone, as is the "sub-allocation" thing, but I do beleive that hotplug should still work in the sense that the space allocation is always done by the PHB, but if you unmap a child bus of this PHB (which seems to be possible), then the code should properly tear down all the HPTE mappings for that area of the PHB allocated IO space. I now always reserve the first 64K of IO space for the bridge with the ISA bus on it. I have moved the code for tracking ISA in a separate file which should also make it smarter if we ever are capable of hot unplugging or re-plugging an ISA bridge. This should have a side effect on platforms like powermac where VGA IOs will no longer work. This is done on purpose though as they would have worked semi-randomly before. The idea at this point is to isolate drivers that might need to access those and fix them by providing a proper function to obtain an offset to the legacy IOs of a given bus.

Also, provide proper semaphore locking in the affected function disable_slot() Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Acked-by: John Rose <johnrose@austin.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

[PATCH] PCI Hotplug: PCI panic on dlpar add (add pci slot to running partition) Removing and then adding a PCI slot to a running partition results in a kernel panic. The current code attempts to add iospace for an entire root bus, which is inappropriate, and silently fails. When a pci device tries to use the iospace, a page fault is taken, as the iospace had not been mapped, and of course the page fault cannot be resolved. This only occurs for PCI adapters using pio, which may be why it hadn't been seen earlier (this seems to have been broken for a while). This patch has survived testing of dozens of slot add and removes.

[PATCH] PCI Hotplug/powerpc: more removal of duplicated code The RPAPHP code contains two routines that appear to be gratuitous copies of very similar pci code. In particular, rpaphp_claim_resource ~~ pci_claim_resource (there is a minor, non-functional difference) rpadlpar_claim_one_bus == pcibios_claim_one_bus (the code is identical) This patch removes the rpaphp versions of the code.

[PATCH] ppc64: bugfix: crash on PHB add 19-rpaphp-crashing.patch This patch fixes a bug related to dlpar PHB add, after a PHB removal. -- The crash was due to the PHB not having a pci_dn structure yet, when the phb is being added. This code survived testing, of adding and removeig the PHB and all slots underneath it, 17 times so far, as of this writing.

[PATCH] fix missing includes I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

[PATCH] Separate pci bits out of struct device_node This patch pulls the PCI-related junk out of struct device_node and puts it in a separate structure, struct pci_dn. The device_node now just has a void * pointer in it, which points to a struct pci_dn for nodes that represent PCI devices. It could potentially be used in future for device-specific data for other sorts of devices, such as virtual I/O devices. Signed-off-by: Paul Mackerras <paulus@samba.org>

[PATCH] PCI Hotplug: rpaphp: Purify hotplug Currently rpaphp registers the following bus types as hotplug slots: 1) Actual PCI Hotplug slots 2) Embedded/Internal PCI slots 3) PCI Host Bridges The 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.

[PATCH] PCI Hotplug: rpaphp: Change slot pci reference The slot structure in the rpaphp module currently references the PCI contents of the slot using the PCI device of the parent bridge. This is unnecessary, since the module is actually interested in the subordinate bus of the bridge. The dependency on a PCI bridge device also prohibits the module from registering hotplug slots that have a root bridge as a parent, since root bridges on PPC64 don't have PCI devices. This patch changes struct slot to reference the PCI subsystem using a pci_bus rather than a pci_dev.

[PATCH] PCI Hotplug: rpaphp: Move VIO registration 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.

Linux-2.6.12-rc2 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!
