2010-02-22ixgbe: prevent speculative processing of descriptors before readyMilton Miller
The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it.

2010-02-19r8169: enable 64-bit DMA by default for PCI Express devices (v2)Robert Hancock
Currently use of 64-bit DMA is disabled in r8169 unless the user passes the use_dac module option. This is reasonable for conventional PCI devices where broken chipsets may not handle dual-address-cycle transfers properly for 32-bit slots and so this may not be safe. However, PCI Express should not have this problem and not using 64-bit DMA results in DMA transfers needlessly using the IOMMU or SWIOTLB. Set the use_dac module parameter to a new default value of -1 which results in 64-bit DMA being enabled by default for PCI Express devices only.

2010-02-19mlx4: replace the dma_sync_single_range_for_cpu/device APIFUJITA Tomonori
There are only two users of the dma_sync_single_range_for_cpu/device API in mainline (mlx4 and ssb). The dma_sync_single_range_for_cpu/device API has never been documented and the dma_sync_single_for_cpu/device API also support a partial sync. This converts mlx4 to use the dma_sync_single_for_cpu/device API (preparations for the removal of the dma_sync_single_range_for_cpu/device API).

2010-02-18macvtap: rework object lifetime rulesArnd Bergmann
This reworks the change done by the previous patch in a more complete way. The original macvtap code has a number of problems resulting from the use of RCU for protecting the access to struct macvtap_queue from open files. This includes - need for GFP_ATOMIC allocations for skbs - potential deadlocks when copy_*_user sleeps - inability to work with vhost-net Changing the lifetime of macvtap_queue to always depend on the open file solves all these. The RCU reference simply moves one step down to the reference on the macvlan_dev, which we only need for nonblocking operations.

Michael Chan noted that there is nothing in the code that would prevent the compiler from delaying the access of the "mapping" member of the newly arrived packet until much later. If this happened after the skb = NULL assignment, it is possible for the driver to pass a bad dma_addr value to pci_unmap_single(). To enforce this ordering, we need a write memory barrier.
