* libata-sff: handle controllers w/o ctl registerTejun Heo2008-03-10
| | | | | | | | | | | SFF incorrectly assumed that ctl register is available for all controllers while some old SFF controllers don't have ctl register. Make SFF handle controllers w/o ctl register by conditionalizing ctl register access and softreset method.

| | | | | | | | | | Some old SFF controllers don't have any way to reset the channel. Currently, this isn't supported and libata EH causes an oops. Allow LLDs w/o any reset method and just assume ATA class in such cases.

* gigaset: fix Oops on module unload regressionTilman Schmidt2008-03-07
| | | | | | | | | | | | | | | | | | | | | The card state mutex was only initialized when a device was connected, but used during unload unconditionally, leading to an Oops if a driver was loaded and unloaded again without ever connecting a device. Fix this by initializing the mutex as soon as the structure is allocated. Also add a missing mutex unlock revealed in the same execution path. This fixes a possible Oops in 2.6.25-rc that was introduced by commit e468c04894f36045cf93d1384183a461014b6840 ("Gigaset: permit module unload"). Thanks to Roland Kletzing for reporting this problem.

This is often because pvr2fb_check_var lacks a __devinitdata annotation or the annotation of pvr2_fix is wrong. This is obviously crap as no such reference exists, but it's a bit closer to reality from older versions which blamed the PCI table. The real problem was a reference to pvr2_var.vmode from pvr2fb_check_var(), as pvr2_var is flagged as __devinitdata (pvr2_fix is also, so at least that part is right). pvr2_var.vmode is just a fancy way of saying FB_VMODE_NONINTERLACED, so we just reference that explicitly instead.

In some cases, the hardcoded values would be larger than the mailbox-command-timeout and result in a needless BIG_HAMMER (ISP reset), the typical recovery mechanism employed in such cases. The second defect in the original code was in the assignment of the default 'ha->r_a_tov' to twice the traditional value. Correct this by setting the value to 10 seconds.

Internal commands are issued with device gdth_cmd_str ready made directly to the card, without any mapping or translations of scsi commands. So here I added a gdth_cmd_str pointer to the gdth_cmndinfo private structure which is then copied directly to host. following this patch is a cleanup that removes the home cooked accessors and reverts them to regular scsi_cmnd accessors. Since they are not used anymore. After review maybe the 2 patches should be squashed together. FIXME: There is still a problem with gdth_get_info(). as reported there is a WARN_ON trigerd in dma_free_coherent() when doing: $ cat /proc/sys/gdth/0 Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Tested-by: Joerg Dorchain: <joerg@dorchain.net> Tested-by: Stefan Priebe <s.priebe@allied-internet.ag> Tested-by: Jon Chelton <jchelton@ffpglobal.com> Cc: Stable Tree <stable@kernel.org> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

This caused a crash in gdth_timer() when module was unloaded. So del_timer_sync the timer before we delete the cards. also the reboot notifier function would crash. So clean that up and fix the crashes.

| * | | [SCSI] aic94xx: fix TMF ascb handling to prevent sequencer panicJames Bottomley2008-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a particularly nasty bug. The problem is that if any internal ascb times out, currently we free it even though it's pending at the sequencer. This results in the sequencer getting terminally confused and the error message: BUG:sequencer:dl:no ascb Being returned when it comes back. The way to fix this is to manage freeing the ascb from the tasklet completion routine, so that we only free it when the sequencer actually returns it. The code is also altered to use on stack completions and transfer variables. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| * | | [SCSI] libsas: use the supplied address for SATA devices rather than changing itJames Bottomley2008-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Once the phy reset is plumbed in properly, SATA error handling fails nastily because we change the port attached_sas_address using the WWN field of the IDENTIFY message. This is a nice thing to do in theory, but it really destroys hotplug because any event on the port causes an automatic mismatch between the sas_address the phy just picked up and the one we propagate into the port. However ugly they are, we have to stick with the sas addresses made up by the phys and expanders. Also does a few cosmetic changes to the way port printing is done to make it clearer how a port is formed. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
| * | | [SCSI] aic94xx: plumb in I_T_nexus_reset task management functionJames Bottomley2008-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently aic94xx has no exported I_T_nexus_reset function. This is a bit of a huge problem, since sas_ata relies on this function to perform an ATA phy reset and also it means that if abort fails, we really have no bigger hammer to hit everything with. Plumb in the I_T_nexus_reset by quiescing the sequencer, sending the correct phy reset (link for ATA and hard for SAS) and then carefully resuming the sequencer again.
