Before that, the iounmap has been called twice with the same value (dev->base and dev->regs.src.bar0) and the iounmap complained about it (iounmap: bad address ...).

2012-04-23[SCSI] scsi_dh_alua: Optimize the STPG commandMoger, Babu
This patch optimizes the set target port group(STPG) command. During our testing, we found that it is not optimal to send stpg command every time the path group switch happens. This patch uses PREF (preferred target port) bit with combination of flags passed by multipath user level tool to optimize this behaviour. If PREF bit is set then it issues a STPG command, otherwise it will let implicit transfer take place. By default there is no change in the behaviour. User tool needs to pass the parameter to make this change take effect. Patch has been tested on NetApp E series storage.

2012-04-23[SCSI] mpt2sas: Fix for panic happening because of improper memory allocationnagalakshmi.nandigama@lsi.com
The ioc->pfacts member in the IOC structure is getting set to zero following a call to _base_get_ioc_facts due to the memset in that routine. So if the ioc->pfacts was read after a host reset, there would be a NULL pointer dereference. The routine _base_get_ioc_facts is called from context of host reset. The problem in _base_get_ioc_facts is the size of Mpi2IOCFactsReply is 64, whereas the sizeof "struct mpt2sas_facts" is 60, so there is a four byte overflow resulting from the memset. Also, there is memset in _base_get_port_facts using the incorrect structure, it should be "struct mpt2sas_port_facts" instead of Mpi2PortFactsReply.

2012-04-23[SCSI] mpt2sas: Fix for hard drive going OFFLINE when hard reset issued and ↵nagalakshmi.nandigama@lsi.com
simultaneously another hard drive is hot unplugged Following the host reset, the firmware discovery is reassigning another hard drive in the topology to the same device handle as that device is getting hot removed. Until the driver device removal routine is called, there will be two hard drive with the matching device handle in the internal device link list. In the device removal routine, a separate function which moves the device from BLOCKED into OFFLINE state. Since this routine is passed with the device handle passed as input parameter, the routine will be traversing the internal device link list searching for matching device handle. This results in two devices with matching device handle, therefore both devices goes OFFLINE. To fix this issue,the input parameter is changed from device handle to SAS address, therefore only the device that is hot unplugged will be placed in OFFLINE state.

2012-04-23[SCSI] mpt2sas : While enabling phy, read the current port number from sas ↵nagalakshmi.nandigama@lsi.com
iounit page 0 instead of page 1 The port number is changing after disabling/enabling phys using the SysFS interface This is because the firmware behavour changed where it would read the the port number then set it to some different value even though Auto Port Config is turned on. With this change of behavour in FW, it is possible that the expanders are moved from one port to another after disabling /enabling phys. This is occuring because the port number in sas iounit page 1 is not matching up to the current port in page 0. In order to fix this the driver is modified to read the current port number from sas iounit page 0 instead of page 1. Also copy the port and phy flags over from page 0 to page 1.

2012-04-23[SCSI] mpt2sas: Improvement were made to better protect the sas_device, ↵nagalakshmi.nandigama@lsi.com
raid_device, and expander_device lists There were possible race conditions surrounding reading an object from the link list while from another context in the driver was removing it. The nature of this enhancement is to rearrange locking so the link lists are better protected. Change set: (1) numerous routines were rearranged so spin locks are held through the entire time a link list object is being read from or written to. (2) added new routines for object deletion from link list. Thus ensuring lock was held during the deletion of the link list object, then and memory for object freed outside the lock. The memory was freed outside the lock so driver had access to device object info which was required for notifying the scsi mid layer that a device was getting deleted. (3) added the ioc->blocking_handles parameter. This is a bitmask used to identify which devices need blocking when there is device loss. This was introduced so that lock can be held for the entire time traversing the link list objects, and the bitmask was set to indicate which device handles need blocking. Oustide the lock the ioc->blocking_handles bitmask is traversed, with the respective device handle the scsi mid layer is called for moving devices into blocking state.

With this implementation, only one IOCTL will be active at any time no matter how many ever controllers are present. This causes poor performance.

2012-04-18Revert "ACPI: Make ACPI interrupt threaded"Thomas Gleixner
This reverts commit 6fe0d0628245fdcd6fad8b837c81e8f7ebc3364d. Paul bisected this regression. The conversion was done blindly and is wrong, as it does not provide a primary handler to disable the level type irq on the device level. Neither does it set the IRQF_ONESHOT flag which handles that at the irq line level. This can't be done as the interrupt might be shared, though we might extend the core to force it. So an interrupt on this line will wake up the thread, but immediately unmask the irq after that. Due to the interrupt being level type the hardware interrupt is raised over and over and prevents the irq thread from handling it. Fail. request_irq() unfortunately does not refuse such a request and the patch was obviously never tested with real interrupts.

Pull virtio fixes from Michael S. Tsirkin: "Here are some virtio fixes for 3.4: a test build fix, a patch by Ren fixing naming for systems with a massive number of virtio blk devices, and balloon fixes for powerpc by David Gibson. There was some discussion about Ren's patch for virtio disc naming: some people wanted to move the legacy name mangling function to the block core. But there's no concensus on that yet, and we can always deduplicate later. Added comments in the hope that this will stop people from copying this legacy naming scheme into future drivers." * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: virtio_balloon: fix handling of PAGE_SIZE != 4k virtio_balloon: Fix endian bug virtio_blk: helper function to format disk names tools/virtio: fix up vhost/test module build
2012-04-16PCI: Retry BARs restoration for Type 0 headers onlyRafael J. Wysocki
Some shortcomings introduced into pci_restore_state() by commit 26f41062f28d ("PCI: check for pci bar restore completion and retry") have been fixed by recent commit ebfc5b802fa76 ("PCI: Fix regression in pci_restore_state(), v3"), but that commit treats all PCI devices as those with Type 0 configuration headers. That is not entirely correct, because Type 1 and Type 2 headers have different layouts. In particular, the area occupied by BARs in Type 0 config headers contains the secondary status register in Type 1 ones and it doesn't make sense to retry the restoration of that register even if the value read back from it after a write is not the same as the written one (it very well may be different). For this reason, make pci_restore_state() only retry the restoration of BARs for Type 0 config headers. This effectively makes it behave as before commit 26f41062f28d for all header types except for Type 0. Tested-by: Mikko Vinni <mmvinni@yahoo.com> Signed-off-by: Rafael J.
