2010-02-28cciss: fix scatter gather chain block dma direction kludgeStephen M. Cameron1-5/+3
cciss: fix scatter gather chain block dma direction kludge The data direction for the chained block of scatter gather elements should always be PCI_DMA_TODEVICE, but was mistakenly set to the direction of the data transfer, then a kludge to fix it was added, in which pci_dma_sync_single_for_device or pci_dma_sync_single_for_cpu was called. If the correct direction is used in the first place, the kludge isn't needed. Signed-off-by: Stephen M. Cameron <[email protected]> Signed-off-by: Jens Axboe <[email protected]>

2010-02-26block: Rename blk_queue_max_sectors to blk_queue_max_hw_sectorsMartin K. Petersen38-47/+47
The block layer calling convention is blk_queue_<limit name>. blk_queue_max_sectors predates this practice, leading to some confusion. Rename the function to appropriately reflect that its intended use is to set max_hw_sectors. Also introduce a temporary wrapper for backwards compability.

2010-02-23tc35815: Remove a wrong netif_wake_queue() call which triggers BUG_ONAtsushi Nemoto1-1/+0
The netif_wake_queue() is called correctly (i.e. only on !txfull condition) from txdone routine. So Unconditional call to the netif_wake_queue() here is wrong. This might cause calling of start_xmit routine on txfull state and trigger BUG_ON. This bug does not happen when NAPI disabled. After txdone there must be at least one free tx slot. But with NAPI, this is not true anymore and the BUG_ON can hits on heavy load. In this driver NAPI was enabled on 2.6.33-rc1 so this is regression from 2.6.32 kernel.

This commit changes nouveau to construct PTEs which look very much like the ones the binary driver creates.

2010-02-22ACPI: Be in TS_POLLING state during mwait based C-state entryPallipadi, Venkatesh1-12/+16
ACPI deep C-state entry had a long standing bug/missing feature, wherein we were sending resched IPIs when an idle CPU is in mwait based deep C-state. Only mwait based C1 was using the write to the monitored address to wake up mwait'ing CPU. This patch changes the code to retain TS_POLLING bit if we are entering an mwait based deep C-state. The patch has been verified to reduce the number of resched IPIs in general and also improves the performance/power on workloads with low system utilization (i.e., when mwait based deep C-states are being used).

2010-02-22i915 / PM: Fix hibernate regression caused by suspend/resume splittingRafael J. Wysocki1-21/+9
Commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash while aborting hibernation) attempted to fix a regression introduced by commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915), but it went too far trying to split the freeze/suspend and resume/thaw parts of the code. As a result, it introduced another regression, which only is visible on some systems. Fix the problem by merging i915_drm_suspend() with i915_drm_freeze() and moving some code from i915_resume() into i915_drm_thaw(), so that intel_opregion_free() and intel_opregion_init() are also executed in the freeze and thaw code paths, respectively.

2010-02-20Input: polldev can cause crash in case when polling disabledSamu Onkalo1-0/+6
When polled input device is opened and closed and there are no other users of polled device, the workqueue is created and destroyed in every open / close operation. It is probable that at some point dynamic allocation of internal parts of the workqueue cause changes to the workqueue. When a work is queued to the workqueue the work struct contains pointers to the workqueue data. If the workqueue has been changed and the work has never been queued to the new workqueue, work-struct contains pointers to the non-existing workqueue. This will cause crash at the work cancellation during device close since cancellation of a work assumes that the workqueue exists. To prevent that, work struct is cleaned up at device close. This keeps work struct clean for the next use. Signed-off-by: Samu Onkalo <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
