Fixed hsdev memleak on sata_dwc_probe() error. As dma_dwc_exit() can be called multiple times without sata_dma_regs and irq_dma changes, it might lead to double free on sequential dma_dwc_exit() calls. So, zero these fields after free calls.

2011-07-23ahci: Enable SB600 64bit DMA on Asus M3AMark Nelson
Like e65cc194f7628ecaa02462f22f42fb09b50dcd49 this patch enables 64bit DMA for the AHCI SATA controller of a board that has the SB600 southbridge. In this case though we're enabling 64bit DMA for the Asus M3A motherboard. It is a new enough board that all of the BIOS releases since the initial release (0301 from 2007-10-22) work correctly with 64bit DMA enabled.

2011-07-23libata: report link resume failure as KERN_WARNING instead of ERRTejun Heo

2011-07-23libata: leave port thawed after reset failureTejun Heo
libata EH intentionally left a port frozen if it failed ata_eh_reset(). The intention was avoiding continuous loop of resets when the controller or attached device is flaky and reporting spurious hotplug events. Once port enters this state, it can be recovered with manual rescan, which seemed reasonable. However, outside of my convoluted test setup, there have been very few reports justifying this choice while there have been more cases where the automatic freezing of the port after hotplug attempt of a faulty device caused confusion and led to unnecessary resets. This patch changes the behavior so that the port is thawed after reset failure. This change doesn't necessarily solve but makes it easier and more intuitive to work around hotplug related problems (ie. re-pluggin or power cycling the device) as reported in the followings. https://bugzilla.kernel.org/show_bug.cgi?id=34712 http://thread.gmane.org/gmane.linux.kernel/1123265/focus=49548 Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Reartes Guillermo <rtguille@gmail.com> Reported-by: Bruce Stenning <b.stenning@indigovision.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2011-07-23block: strict rq_affinityDan Williams
Some systems benefit from completions always being steered to the strict requester cpu rather than the looser "per-socket" steering that blk_cpu_to_group() attempts by default. This is because the first CPU in the group mask ends up being completely overloaded with work, while the others (including the original submitter) has power left to spare. Allow the strict mode to be set by writing '2' to the sysfs control file. This is identical to the scheme used for the nomerges file, where '2' is a more aggressive setting than just being turned on. echo 2 > /sys/block/<bdev>/queue/rq_affinity Cc: Christoph Hellwig <hch@infradead.org> Cc: Roland Dreier <roland@purestorage.com> Tested-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
