| * ACPI: don't duplicate input events on netlinkZhang Rui2007-08-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous events patch added a netlink event for every user of the legacy /proc/acpi/event interface. However, some users of /proc/acpi/event are really input events, and they already report their events via the input layer. Introduce a new interface, acpi_bus_generate_netlink_event(), which is explicitly called by devices that want to repoprt events via netlink. This allows the input-like events to opt-out of generating netlink events. In summary: events that are sent via netlink: ac/battery/sbs thermal processor thinkpad_acpi dock/bay events that are sent via input layer: button video hotkey thinkpad_acpi hotkey asus_acpi/asus-laptop hotkey sonypi/sonylaptop Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| * [POWERPC] Rewrite IO allocation & mapping on powerpc64Benjamin Herrenschmidt2007-06-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | PCI: hotplug: acpiphp: avoid acpiphp "cannot get bridge info" PCI hotplug ↵Gary Hade2007-07-111-2/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | failure On some systems, the ACPI bus check event can reference a bridge that is higher in the ACPI hierarchy than the bridge immediately above the hotplug PCI slot into which an adapter was just inserted. The current 'acpiphp' code expects the bus check event to reference the bridge immediately above the slot that received the adapter so the hotplug operation can fail on these systems with the message "acpiphp_glue: cannot get bridge info". This change fixes the problem by re-enumerating all slots that lie below the bridge referenced by the bus check event, including those slots that may be located under lower level PCI-to-PCI bridge(s).

This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

* | sysfs: add parameter "struct bin_attribute *" in .read/.write methods for ↵Zhang Rui2007-07-111-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

* | sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-111-1/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded.

* Detach sched.h from mm.hAlexey Dobriyan2007-05-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

* | PCI: rpaphp: Remove semaphoresLinas Vepstas2007-05-021-35/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove the semaphores from the get routine. These do not appear to be protecting anything that I can make out, and they also do not seem to be required by the hotplug driver.

* | PCI: rpaphp: Use pcibios_remove_pci_devices() symmetricallyLinas Vepstas2007-05-021-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | At first blush, the disable_slot() routine does not look at all like its symmetric with the enable_slot() routine; as it seems to call a very different set of routines. However, this is easily fixed: pcibios_remove_pci_devices() does the right thing.

* | PCI: rpaphp: Document is_php_dn()Linas Vepstas2007-05-021-13/+29
| | | | | | | | | | | | | | | | | | | | | | | | Fix up the documentation: the rpaphp_add_slot() does not actually handle embedded slots: in fact, it ignores them. Fix the flow of control in the routine that checks for embedded slots.

| | | | | | | | | | | | | | | | | | | | | | Document some of the interaction between dlpar and hotplug. viz, the a dlpar remove of a htoplug slot uses hotplug to remove it.

| | | | | | | | | | | | | | | | | | | | | | | | | | Rename rpaphp_register_pci_slot() because its easy to confuse with rpaphp_register_slot() even though it does something completely different. Rename it to rpaphp_enable_slot() because its almost identical to enbale_slot().
