2014-07-31rapidio/tsi721_dma: fix failure to obtain transaction descriptorAlexandre Bounine1-1/+7
This is a bug fix for the situation when function tsi721_desc_get() fails to obtain a free transaction descriptor. The bug usually results in a memory access crash dump when data transfer scatter-gather list has more entries than size of hardware buffer descriptors ring. This fix ensures that error is properly returned to a caller instead of an invalid entry. This patch is applicable to kernel versions starting from v3.5.

2014-07-31mm, thp: do not allow thp faults to avoid cpuset restrictionsDavid Rientjes1-8/+8
The page allocator relies on __GFP_WAIT to determine if ALLOC_CPUSET should be set in allocflags. ALLOC_CPUSET controls if a page allocation should be restricted only to the set of allowed cpuset mems. Transparent hugepages clears __GFP_WAIT when defrag is disabled to prevent the fault path from using memory compaction or direct reclaim. Thus, it is unfairly able to allocate outside of its cpuset mems restriction as a side-effect. This patch ensures that ALLOC_CPUSET is only cleared when the gfp mask is truly GFP_ATOMIC by verifying it is also not a thp allocation.

2014-07-31mm/page-writeback.c: fix divide by zero in bdi_dirty_limits()Maxim Patlasov1-3/+3
Under memory pressure, it is possible for dirty_thresh, calculated by global_dirty_limits() in balance_dirty_pages(), to equal zero. Then, if strictlimit is true, bdi_dirty_limits() tries to resolve the proportion: bdi_bg_thresh : bdi_thresh = background_thresh : dirty_thresh by dividing by zero.

2014-07-31staging: unisys: add sysfs entries for parahotplug supportBenjamin Romer1-0/+52
This patch adds new a new directory parahotplug to the visorchipset sysfs directory, and two new attributes, deviceenabled, and devicedisabled, into the new directory, to add s-Par parahotplug support. The parahotplug interface is used to deal with SR-IOV recovery situations on s-Par guest partitions. The command service partition will send a message to a guest when an SR-IOV device that guest is using needs to be temporarily removed. The message triggers a udev event that will cause a recovery script to run. When that script has completed its work, it will write to one of the parahotplug interfaces to send a message back to Command, indicating that the recovery action has completed. When a guest that is sharing an SR-IOV device is restarted, that guest will take down the PF driver on the device, but any guests with VFs will not know that their device needs to be reset as well. The recovery script makes it so the device will be shut down fully and then restarted after the sharing guest comes back up, and ensures that the timing is correct.
