2008-02-26maple: fix device detectionAdrian McMenamin
The maple bus driver that went into the kernel mainline in September 2007 contained some bugs which were revealed by the update of the kobj code for the current release series. Unfortunately those bugs also helped ensure maple devices were properly detected. This patch (against the current git) now ensures that devices are properly detected again. (A previous attempt to fix this by delaying initialisation only partially fixed this - as became apparent when the bus was fully loaded) Signed-off-by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-02-25RDMA/nes: Resurrect error path dead codeChien Tung
Adrian Bunk pointed out that a Coverity scan found some apparently dead code in nes_verbs.c that really shouldn't have been dead. The function nes_create_cq() was missing the assignment err = 1; just prior to an iteration that conditionally set err = 0 if a PBL was found for a given virtual CQ. I also noticed we should have been returning -EFAULT on a couple related error paths.

2008-02-25RDMA/cxgb3: Fix shift calc in build_phys_page_list() for 1-entry page listsBryan Rosenburg
A single entry (addr 0x10001000, size 0x2000) will get converted to page address 0x10000000 with a page size of 0x4000. The code as it stands doesn't address the single buffer case, but in fact it allows the subsequent single-buffer special case to be eliminated entirely. Because the mask now includes the (page adjusted) starting and ending addresses, the general case works for the single buffer case as well.

2008-02-25latencytop: fix kernel panic while reading latency proc fileHiroshi Shimamoto
Reading /proc/<pid>/latency or /proc/<pid>/task/<tid>/latency could cause NULL pointer dereference. In lstats_open(), get_proc_task() can return NULL, in which case the kernel will oops at lstats_show_proc() because m->private is NULL. When get_proc_task() returns NULL, the kernel should return -ENOENT. This can be reproduced by the following script. while : do date bash -c 'ls > ls.$$' & pid=$! cat /proc/$pid/latency & cat /proc/$pid/latency & cat /proc/$pid/latency & cat /proc/$pid/latency done Signed-off-by: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-02-24[SCSI] aic94xx: fix TMF ascb handling to prevent sequencer panicJames Bottomley
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>

2008-02-23[SCSI] libsas: use the supplied address for SATA devices rather than changing itJames Bottomley
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>
2008-02-23[SCSI] aic94xx: plumb in I_T_nexus_reset task management functionJames Bottomley
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.

2008-02-23[SCSI] libsas: export sas_find_local_phy functionJames Bottomley
