2010-01-17[SCSI] zfcp: Introduce bsg_timeout callback.Swen Schillig
Introduce a zfcp callback for timeouts triggered from FC BSG. With zfcp, the underlying hardware cannot abort CT or ELS requests, so there is nothing to do when the block layer timeout expires. To avoid interference with the block layer timeout, simply indicate that the block layer timer should be reset. The timer running in the hardware for the pending CT or ELS request will return the request when it expires.

2010-01-17[SCSI] scsi_lib: Fix bug in completion of bidi commandsBoaz Harrosh
Because of the terrible structuring of scsi-bidi-commands it breaks some of the life time rules of a scsi-command. It is now not allowed to free up the block-request before cleanup and partial deallocation of the scsi-command. (Which is not so for none bidi commands) The right fix to this problem would be to make bidi command a first citizen by allocating a scsi_sdb pointer at scsi command just like cmd->prot_sdb. The bidi sdb should be allocated/deallocated as part of the get/put_command (Again like the prot_sdb) and the current decoupling of scsi_cmnd and blk-request should be kept. For now make sure scsi_release_buffers() is called before the call to blk_end_request_all() which might cause the suicide of the block requests. At best the leak of bidi buffers, at worse a crash, as there is a race between the existence of the bidi_request and the free of the associated bidi_sdb. The reason this was never hit before is because only OSD has the potential of doing asynchronous bidi commands. (So does bsg but it is never used) And OSD clients just happen to do all their bidi commands synchronously, up until recently.

2010-01-17[SCSI] mptsas: Fix issue with chain pools allocation on katmaiAnatolij Gustschin
Since commit 9d2e9d66a3f032667934144cd61c396ba49f090d mptsas driver fails to allocate memory for the MPT chain buffers for second LSI adapter on PPC440SPe Katmai platform: ... ioc1: LSISAS1068E B3: Capabilities={Initiator} mptbase: ioc1: ERROR - Unable to allocate Reply, Request, Chain Buffers! mptbase: ioc1: ERROR - didn't initialize properly! (-3) mptsas: probe of 0002:31:00.0 failed with error -3 This commit increased MPT_FC_CAN_QUEUE value but initChainBuffers() doesn't differentiate between SAS and FC causing increased allocation for SAS case, too. Later pci_alloc_consistent() fails to allocate increased chain buffer pool size for SAS case. Provide a fix by looking at the bus type and using appropriate MPT_SAS_CAN_QUEUE value while calculation of the number of chain buffers.

2010-01-17[SCSI] aacraid: fix File System going into read-only modePenchala Narasimha Reddy Chilakala, ERS-HCLTech
These particular problems were reported by Cisco and SAP and customers as well. Cisco reported on RHEL4 U6 and SAP reported on SLES9 SP4 and SLES10 SP2. We added these fixes on RHEL4 U6 and gave a private build to IBM and Cisco. Cisco and IBM tested it for more than 15 days and they reported that they did not see the issue so far. Before the fix, Cisco used to see the issue within 5 days. We generated a patch for SLES9 SP4 and SLES10 SP2 and submitted to Novell. Novell applied the patch and gave a test build to SAP. SAP tested and reported that the build is working properly. We also tested in our lab using the tools "dishogsync", which is IO stress tool and the tool was provided by Cisco. Issue1: File System going into read-only mode Root cause: The driver tends to not free the memory (FIB) when the management request exits prematurely. The accumulation of such un-freed memory causes the driver to fail to allocate anymore memory (FIB) and hence return 0x70000 value to the upper layer, which puts the file system into read only mode. Fix details: The fix makes sure to free the memory (FIB) even if the request exits prematurely hence ensuring the driver wouldn't run out of memory (FIBs). Issue2: False Raid Alert occurs When the Physical Drives and Logical drives are reported as deleted or added, even though there is no change done on the system Root cause: Driver IOCTLs is signaled with EINTR while waiting on response from the lower layers. Returning "EINTR" will never initiate internal retry. Fix details: The issue was fixed by replacing "EINTR" with "ERESTARTSYS" for mid-layer retries.

2010-01-16revert "drivers/video/s3c-fb.c: fix clock setting for Samsung SoC Framebuffer"Mark Brown
Fix divide by zero and broken output. Commit 600ce1a0fa ("fix clock setting for Samsung SoC Framebuffer") introduced a mandatory refresh parameter to the platform data for the S3C framebuffer but did not introduce any validation code, causing existing platforms (none of which have refresh set) to divide by zero whenever the framebuffer is configured, generating warnings and unusable output. Ben Dooks noted several problems with the patch: - The platform data supplies the pixclk directly and should already have taken care of the refresh rate. - The addition of a window ID parameter doesn't help since only the root framebuffer can control the pixclk. - pixclk is specified in picoseconds (rather than Hz) as the patch assumed. and suggests reverting the commit so do that. Without fixing this no mainline user of the driver will produce output.

On Ironlake, there is an interrupt master control bit. With the bit disabled before clearing IIR, we do not need to handle extra interrupt in a loop. This patch removes the loop in Ironlake interrupt handler. It fixed irq lost issue on some Ironlake platforms.

2010-01-15serial: sh-sci: using correct fifo size for SCIF and SCIFA ports.Markus Pietrek
The sh-sci driver used the wrong fifosize for PORT_SCIFA and PORT_SCIF ports. If an incorrect size is used, the serial core will enforce an early shutdown on the port, especially with baudrates < 9600.
