Becker-derived drivers often have the 'io_size' member in their chip info struct, indicating the minimum required size of the I/O resource (usually a PCI BAR). For many situations, this number is either constant or irrelevant (due to pci_iomap convenience behavior). This change removes the io_size invariant member, and replaces it with a compile-time constant. Drivers updated: fealnx, gt96100eth, winbond-840, yellowfin Additionally, - gt96100eth: unused 'drv_flags' removed from gt96100eth - winbond-840: unused struct match_info removed - winbond-840: mark pci_id_tbl[] const, __devinitdata Signed-off-by: NJeff Garzik <jeff@garzik.org>

When in-kernel net drivers branched from Donald Becker's vanilla driver set, in the days before BitKeeper and git, a driver changelog was maintained in the driver source code. These days, the kernel's changelog is far superior and much more accurate, so the in-driver changelogs are removed. Another relic of the Becker/kernel split was version numbering, using "foo-LKx.y.z" notation, resulting in weird version numbers like "1.17b-LK1.1.9". These drivers are for older hardware, and see few changes these days, so the version numbers were all bumped to something more simple. Finally, in xircom_tulip_cb specifically, an additional cleanup removes the always-enabled CARDBUS cpp macro. Signed-off-by: NJeff Garzik <jeff@garzik.org>

- Remove in-source changelog, it's in the global kernel history. - convert silly and useless version to useful one - replace invariant pci_id_tbl[]::io_size uses with EPIC_TOTAL_SIZE - remove now-unused io_size member from pci_id_tbl[] - current kernel style prefers dev_printk() for the rare ethernet driver messages that cannot print an 'eth%d' prefix.

mthca: initialize send and receive queue locks separately lockdep identifies a lock by the call site of its initialization. By initializing the send and receive queue locks in mthca_wq_init() we confuse lockdep. It warns that that the ordered acquiry of both locks in mthca_modify_qp() is recursive acquiry of one lock: ============================================= [ INFO: possible recursive locking detected ] --------------------------------------------- modprobe/1192 is trying to acquire lock: (&wq->lock){....}, at: [<f892b4db>] mthca_modify_qp+0x60/0xa7b [ib_mthca] but task is already holding lock: (&wq->lock){....}, at: [<f892b4ce>] mthca_modify_qp+0x53/0xa7b [ib_mthca] Initializing the locks separately in mthca_alloc_qp_common() stops the warning and will let lockdep enforce proper ordering on paths that acquire both locks.

[unused on non-lockdep] - a subclass parameter to __blkdev_put(), which is a new internal function for the main blkdev_put*() functions. [parameter unused on non-lockdep kernels, except for two sanity check WARN_ON()s] these functions carry no semantical difference - they only express object dependencies towards the lockdep subsystem.

In usbfs's fs_remove_file() function, the aim is to remove a file or directory from usbfs. This is done by first taking the i_mutex of the parent directory of this file/dir via mutex_lock(&parent->d_inode->i_mutex); and then to call either usbfs_rmdir() for a directory or usbfs_unlink() for a file. Both these functions then take the i_mutex for the to-be-removed object themselves: mutex_lock(&inode->i_mutex); This is a classical parent->child locking order relationship that the VFS uses all over the place; the VFS locking rule is "you need to take the parent first". This patch annotates the usbfs code to make this explicit and thus informs the lockdep code that those two locks indeed have this relationship. The rules for unlink that we already use in the VFS for unlink are to use I_MUTEX_PARENT for the parent directory, and a normal mutex for the file itself; this patch follows that convention. Has no effect on non-lockdep kernels.

ieee1394 reuses the skb infrastructure of the networking code, and uses two skb-head queues: ->pending_packet_queue and hpsbpkt_queue. The latter is used in the usual fashion: processed from a kernel thread. The other one, ->pending_packet_queue is also processed from hardirq context (f.e. in hpsb_bus_reset()), which is not what the networking code usually does (which completes from softirq or process context). This locking assymetry can be totally correct if done carefully, but it can also be dangerous if networking helper functions are reused, which could assume traditional networking use. It would probably be more robust to push this completion into a workqueue - but technically the code can be 100% correct, and lockdep has to be taught about it. The solution is to split the ->pending_packet_queue skb-head->lock class from the networking lock-class by using a private lock-validator key. Has no effect on non-lockdep kernels.

The PS/2 code has a natural device order and there is a one level recursion in this device order in terms of the cmd_mutex; annotate this explicit recursion as ok.

Machine checks on s390 are always enabled (except in the machine check handler itself). Therefore use lockdep_off()/on() in the machine check handler to avoid deadlocks in the lock validator.
