The following messages are of interest only when debugging aio. Otherwise, they are just console clutter.

- fix a (now-) bug in kernel/softirq.c, it did a wakeup outside any atomic regions, which falsely identified random processes as a non-atomic wakeup, and which causes random priority boost to be distributed. - reset the initial idle thread's priority back to PRIO_MAX after doing the wakeup_forked_process() - correct preemption relies on this. - update current->prio immediately after a backboost. - clean up effective_prio() & sleep_avg calculations so that there are fewer RT-task special cases. This has the advantage of the sleep_avg being maintained even for RT tasks - this could be advantegous for tasks that briefly enter/exit RT mode.

Seems there is a memleak on error exit path in drivers/char/vt.c, here's the patch. Found with help of smatch + enhanced unfree script.

__activate_task() and wake_up_forked_process() should call nr_running_inc(rq) rather than doing a rq->nr_running++. Noted by Rick Lindsley

The console initcall patch that went in contains a typo that prevents alpha from building.

The stack reducing patch that recently went in prevent alpha from building (missing some ELF_CORE_COPY_XFPREGS ifdefs). The excluded patch fixes it.

This one simply sets TARGET_CPUS to cpu_callout_map instead of cpu_online_map so that when we finally do boot we actually use the other cpus for servicing interrupts.

This change was wrong. pfn_to_nid is a macro.

From Rusty Lynch: * makes sysfs cleanup the buffer->data allocated by the attribute write functions * fixes a bug that causes the kernel to oops when somebody attempts to write to the file.

This patch was previously integrated, but dropped erroneously by a bk merge. This fixes file cleanup during a sysfs directory removal by deleting files from ->d_subdirs as they're iterated over, then checking if we can get a reference on them.

Andy Grover told me this should be posted here. It allows ACPI to compile even with PCI turned off. Patch against 2.5.60.

ia 64 part of the patch. This gives you a 32 bit version of sys_futex (hopefully).

concurrent renames in another directory. I doubt this can be triggered in practice, and the fix is a bit heavy-handed, but let's see if numbers can show that the simple fix doesn't show any real lock contention.

This is the "boot sector removal" patch for i386 updated for Linux 2.5.63-bk7. The only change against the 2.5.59 version is that the FDOPTS Makefile variable, which lets one create a floppy image with arbitrary kernel options, has been merged from the x86-64 version, and the comments have been updated. The patch removes the in-kernel boot sector, which these days rarely work correctly (it only supports up to 1 MB kernels, and only work on legacy floppies -- not on IDE or USB devices, nor on any kind of emulated devices like El Torito), replaces it with a placeholder stub, and sets up the Makefile targets to create floppies or floppy images using SYSLINUX. The FDOPTS Makefile variable can be used to set kernel command line options (thanks to a suggestion by Andi Kleen.) Note that the same change has already been applied to the x86-64 architecture. The last hunk of the patch corrects a comment in that architecture.

Now we tackle pci_add_new_bus and pci_scan_bridge. The hotplug code currently uses this, but I'd like it to die off; pci_scan_bridge() should be used to scan behind bridges. This may mean hotplug needs some changes to pci_scan_bridge - if so, we need to find out what changes are required and fix it. pci_alloc_child_bus() does what pci_add_new_bus() did, except it doesn't attach the new bus to the parents list of child buses. The only way this bus can be reached from the parent bus is by scanning the parents devices list, and locating a device with a non-NULL subordinate bus. The only code which should be doing this is the PCI code. Since the new bus will have an empty list head for bus->node, we can detect unattached buses prety easily. (see pci-3.diff.) pci_scan_bridge() changes slightly - we use our new pci_scan_child_bus() function from pci-3.diff, which doesn't attach devices to the global tree. This means callers of pci_scan_child_bus() and pci_scan_bridge() (ie, hotplug) will need to call pci_bus_add_devices().

- Convert setup-bus.c resource allocation to scan bus->devices rather than bus->children. As noted previously, newly discovered child buses will not be on the parents list of children buses, so when we're trying to assign resources, we need to scan the bus for devices with subordinate buses rather than using the list of children buses.

The pci_find* functions search using the following lists: bus->children (for subordinate buses) pci_root_buses (for all root buses) pci_devices (for devices) This leaves one list which we can add devices to without any drivers finding the new devices before we've finished with them. - initialise bus->node list head. - pci_scan_slot will scan the specified slot, and add the discovered devices to the bus->devices list only. These devices will not appear on the global device list, and do not show in sysfs, procfs. pci_scan_slot returns the number of functions found. If you want to find the devices, you have to scan bus->devices and look for devices where list_empty(&dev->global_list) is true. - new function "pci_bus_add_devices" adds newly discovered devices to the global device lists, and handles the sysfs and procfs stuff, making the devices available to drivers. All our buses which have an empty list head are treated as "new" (since they are not attached to the parent buses list of children) and are also added. Currently, no buses will be in this state when this function is called. - new function "pci_scan_child_bus" scans a complete bus, building a list of devices on bus->devices only, performing bus fixups via pcibios_fixup_bus() and scanning behind bridges. It does make devices externally visible. - pci_do_scan_bus retains its original behaviour - ie, it scans and makes devices available immediately.

- Eliminate the stack allocation of a struct pci_dev, and make pci_scan_slot() take a bus and a devfn argument. - Add "dev->multifunction" to indicate whether this is a multifunction device. - Run header fixups before inserting the new pci device into any device lists or announcing it to the drivers. - Convert some more stuff to use the list_for_each* macro(s).
-
Russell King authored
- Separate out bus resource allocator (pci_bus_alloc_resource) - Provide pci_enable_bridges to setup command register for all pci bridges.
