2007-10-21[SCSI] aic7xxx: Add suspend/resume supportHannes Reinecke
The aic7xxx driver already contains fragments for suspend/resume support. So we only need to update them to the current interface and have full PCI suspend/resume.

* Convert files to UTF-8. * Also correct some people's names (one example is Eißfeldt, which was found in a source file. Given that the author used an ß at all in a source file indicates that the real name has in fact a 'ß' and not an 'ss', which is commonly used as a substitute for 'ß' when limited to 7bit.) * Correct town names (Goettingen -> Göttingen) * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313) Signed-off-by: Jan Engelhardt <jengelh@gmx.de> Signed-off-by: Adrian Bunk <bunk@kernel.org>

2007-10-19Change struct marker usersMathieu Desnoyers
Prior to use struct marker in the linux kernel markers, we need to clean two drivers which use this structure name. Change bonding driver types : - struct marker to struct bond_marker. - marker_t to bond_marker_t. - marker_header to bond_marker_header. - marker_header_t to bond_marker_header_t. Change qla4xxx struct marker_entry usage : - Change struct marker_entry for struct qla4_marker_entry.

2007-10-19Use helpers to obtain task pid in printksPavel Emelyanov
The task_struct->pid member is going to be deprecated, so start using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in the kernel. The first thing to start with is the pid, printed to dmesg - in this case we may safely use task_pid_nr(). Besides, printks produce more (much more) than a half of all the explicit pid usage.

2007-10-18[libata] kill ata_sg_is_last()Jeff Garzik
Short term, this works around a bug introduced by early sg-chaining work. Long term, removing this function eliminates a branch from a hot path loop in each scatter/gather table build. Also, as this code demonstrates, we don't need to _track_ the end of the s/g list, as long as we mark it in some way. And doing so programatically is nice. So its a useful cleanup, regardless of its short term effects. Based conceptually on a quick patch by Jens Axboe. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2007-10-15scsi/gdth: fix crash in gdth_timeout if no gdth controllers foundLinus Torvalds
If the gdth module is loaded (or compiled in), the gdth_timeout function gets started even if no actual gdth controllers are found b the probing. That ends up not only being unnecessary, but also causes a crash due to the function blindly just trying to pick the first entry off the "gdth_instances" list, and accessing it - which obviously doesn't work if the list is empty!
