2007-10-17nbd: change a parameter's type to remove a memcpy callDenis Cheng
This memcpy looks so strange, in fact it's merely a pointer dereference, so I change the parameter's type to refer it more directly, this could make the memcpy not needed anymore. In the function nbd_read_stat where nbd_find_request is only once called, the parameter served should be transformed accordingly.

2007-10-17kill DECLARE_MUTEX_LOCKEDChristoph Hellwig
DECLARE_MUTEX_LOCKED was used for semaphores used as completions and we've got rid of them. Well, except for one in libusual that the maintainer explicitly wants to keep as semaphore. So convert that useage to an explicit sema_init and kill of DECLARE_MUTEX_LOCKED so that new code is reminded to use a completion.

2007-10-17Driver for the Atmel on-chip SSC on AT32AP and AT91Hans-Christian Egtvedt
The Synchronous Serial Controller (SSC) on Atmel microprocessors are capable of tranceiving many frame based protocols, like I2S. Tested on the AT32AP7000/ATSTK1000. This driver is used in the ALSA sound driver for the AT73C213 external DAC on the ATSTK1000 development board for AVR32. This sound driver will be submitted soon. Hardware documentation can be found in the AT32AP7000 data sheet, which can be downloaded from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 [akpm@linux-foundation.org: init spinlock at compile time] Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Acked-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Cc: David Brownell <david-b@pacbell.net> Cc: Andrew Victor <andrew@sanpeople.com> Cc: Patrice Vilchez <patrice.vilchez@rfo.atmel.com> Cc: Nicolas Ferre <nicolas.ferre@rfo.atmel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

main change: * greatly improve per-NIC probe diagnostic output. Similar to other net drivers, print out MAC address, PHY info, and various hardware and software flags that may be relevant. other changes: * similar to other net drivers, only print the initial version message when we have found at least one board. * don't bother to print error message when pci_enable_device() fails, it will do so for us. * use dev_printk() rather than printk() in nv_probe(). This gives use a standardized output similar to the rest of the kernel, and eliminates the need to manually print out PCI bus id. * use DRV_NAME constant where appropriate * clean struct pci_driver indentation Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2007-10-17firewire: fw-ohci: enforce read order for selfID generationStefan Richter
It seems unlikely, but access to self_id_cpu[0] could at least in theory be deferred until after the loop over self_id_cpu[1..n] or even after the subsequent reg_read. Enforce the desired order by a read barrier. Also prevent the reg_read from being reordered relative to the for loop. This isn't necessary if the loop's conditional printk counts as an implicit barrier, but better make it explicit. (self_id_cpu[] is a coherent DMA buffer.)

2007-10-17firewire: fw-sbp2: use an own workqueue (fix system responsiveness)Stefan Richter
Firewire-sbp2 did very uncooperative things in the kernel's shared workqueue: Sleeping until reception of management status from the target for up to 2 seconds, and performing SCSI inquiry and all of the setup of SCSI command set drivers via scsi_add_device. If there were transient or permanent error conditions, this caused long blockage of the kernel's events process, noticeable e.g. by blocked keyboard input. We now allocate a workqueue process exclusive to fw-sbp2. As a side effect, this also increases parallelism of fw-sbp2's login and reconnect work versus fw-core's device discovery and device update work which is performed in the shared workqueue.

2007-10-17firewire: fw-sbp2: expose module parameter for workaroundsStefan Richter
On rare occasions, the ability to set one of the workaround flags at runtime may save the day. People who experience I/O errors with firewire-sbp2 while the old sbp2 driver worked for them should try workarounds=1 and report to the devel mailinglist whether that improves things. Firewire-sbp2 defaults to the SCSI stack's maximum transfer size per command, while sbp2 limits them to 128 kBytes. Flag 1 accomplishes just that.

Also, calls to csr1212_keep_keyval(kv) should occur before kv is being used.
