* mm: Remove slab destructors from kmem_cache_create().Paul Mundt2007-07-19
| | | | | | | | | | | | | | Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

* ieee1394: eth1394: revert parent device to that in 2.6.20Stefan Richter2007-07-09
| | | | | | | | | | | After ieee1394 was converted away from class_device like the networking subsystem was already in 2.6.21, eth1394's device may point to the fw-host device as its parent again like in 2.6.20. This affects userspace tools which examine the sysfs representation of eth1394's device. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* ieee1394: fix to ether1394_tx in ether1394.cCarlos E. Ugarte2007-06-16
| | | | | | | | | | | | This patch fixes a problem that occurs when packets cannot be sent across the ieee1394 bus and we return NETDEV_TX_BUSY in the net driver "hard start xmit" routine ether1394_tx. When we return NETDEV_TX_BUSY the stack will call ether1394_tx again with the same skb. So we need to restore the header to look like it did before we munged it for xmit over ieee1394.

* ieee1394: eth1394: bring back a parent deviceStefan Richter2007-05-27
| | | | | | | | | | | | | | | | This adds a real parent device to eth1394's ethX device like in Linux 2.6.20 and older. However, due to unfinished conversion of the ieee1394 away from class_device, we now refer to the FireWire controller's PCI device as the parent, not to the ieee1394 driver's fw-host device. Having a real parent device instead of a virtual one allows udev scripts to distinguish eth1394 interfaces from networking bridges, bondings and the likes.

* ieee1394: eth1394: handle tlabel exhaustionStefan Richter2007-05-27
| | | | | | | | | | | | | When eth1394 was unable to acquire a transaction label, it just dropped outgoing packets without attempt to resend them later. The transmit queue is now halted if no tlabel is available to ->hard_start_xmit(). A workqueue job is then scheduled to catch the moment when ieee1394 recycled the next lot of tlabels.

* ieee1394: eth1394: don't autoload by hotplug when ohci1394 startsStefan Richter2007-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, ieee1394 put an IP-over-1394 capability entry into each new host's config ROM. As soon as the controller was initialized --- i.e. right after modprobe ohci1394 --- this entry triggered a hotplug event which typically caused auto-loading of eth1394. This irritated or annoyed many users and distributors. Of course they could blacklist eth1394, but then ieee1394 wrongly advertized IP-over- 1394 capability to the FireWire bus. Therefore - remove the offending kernel config option IEEE1394_CONFIG_ROM_IP1394, - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was loaded. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 . To emulate the behaviour of older kernels, simply add the following to to /etc/modprobe.conf: install ohci1394 /sbin/modprobe eth1394; \ /sbin/modprobe --ignore-install ohci1394 Note, autoloading of eth1394 when an _external_ IP-over-1394 capable device is discovered is _not_ affected by this patch.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* ieee1394: Consolidate driver registeringBen Collins2006-12-07
| | | | | | | | | | | | | This patch consolidates some bookkeeping for driver registering. It closely models what pci_register_driver() does. The main addition is that the owner of the driver is set, so we get a proper symlink for /sys/bus/ieee1394/driver/*/module. Also moves setting of name and bus type into nodemgr. Because of this, we can remove the EXPORT_SYMBOL for ieee1394_bus_type, since it's now only used in ieee1394.ko. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

A probing function is added to nodemgr's config ROM fetching routine which adjusts the allowable speed if an access problem was encountered. Pros and Cons of the approach: + minimum code footprint to support this less widely used hardware + nearly no overhead for unaffected hardware - ineffective before nodemgr began to read the ROM of affected nodes - ineffective if ieee1394 is loaded with disable_nodemgr=1 The speed map CSRs which are published to the bus are not touched by the patch.

* [PATCH] Sync up ieee-1394Ben Collins2005-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | Lots of this patch is trivial code cleanups (static vars were being intialized to 0, etc). There's also some fixes for ISO transmits (max buffer handling). Aswell, we have a few fixes to disable IRM capabilites correctly. We've also disabled, by default some generally unused EXPORT symbols for the sake of cleanliness in the kernel. However, instead of removing them completely, we felt it necessary to have a config option that allowed them to be enabled for the many projects outside of the main kernel tree that use our API for driver development. The primary reason for this patch is to revert a MODE6->MODE10 RBC conversion patch from the SCSI maintainers. The new conversions handled directly in the scsi layer do not seem to work for SBP2. This patch reverts to our old working code so that users can enjoy using Firewire disks and dvd drives again. We are working with the SCSI maintainers to resolve this issue outside of the main kernel tree. We'll merge the patch once the SCSI layer's handling of the MODE10 conversion is working for us.

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!
