Really minor stuff in here, the only real functional change is making the auto-unplug threshold a per-queue entity.

According to the usbmon source, it dumps one byte after the other. The first 4 bytes are US_BULK_CB_SIGN which is correct. After that we see the TAG which is 0x5e. The cdb is 0x00 in this example.

Fix from Eric Dumazet. 11) do_tcp_sendpage() unloads the send queue way too fast, because it invokes tcp_push() when it shouldn't. Let the natural sequence generated by the splice paths, and the assosciated MSG_MORE settings, guide the tcp_push() calls. Otherwise what goes out of TCP is spaghetti and doesn't batch effectively into GSO/TSO clusters. From Eric Dumazet. 12) Once we put a SKB into either the netlink receiver's queue or a socket error queue, it can be consumed and freed up, therefore we cannot touch it after queueing it like that. Fixes from Eric Dumazet. 13) PPP has this annoying behavior in that for every transmit call it immediately stops the TX queue, then calls down into the next layer to transmit the PPP frame. But if that next layer can take it immediately, it just un-stops the TX queue right before returning from the transmit method. Besides being useless work, it makes several facilities unusable, in particular things like the equalizers. Well behaved devices should only stop the TX queue when they really are full, and in PPP's case when it gets backlogged to the downstream device. David Woodhouse therefore fixed PPP to not stop the TX queue until it's downstream can't take data any more. 14) IFF_UNICAST_FLT got accidently lost in some recent stmmac driver changes, re-add. From Marc Kleine-Budde. 15) Fix link flaps in ixgbe, from Eric W. Multanen. 16) Descriptor writeback fixes in e1000e from Matthew Vick. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (47 commits) net: fix a race in sock_queue_err_skb() netlink: fix races after skb queueing doc, net: Update ndo_start_xmit return type and values doc, net: Remove instruction to set net_device::trans_start doc, net: Update netdev operation names doc, net: Update documentation of synchronisation for TX multiqueue doc, net: Remove obsolete reference to dev->poll ethtool: Remove exception to the requirement of holding RTNL lock MAINTAINERS: update for Marvell Ethernet drivers bonding: properly unset current_arp_slave on slave link up phonet: Check input from user before allocating tcp: tcp_sendpages() should call tcp_push() once ipv6: fix array index in ip6_mc_add_src() mlx4: allocate just enough pages instead of always 4 pages stmmac: re-add IFF_UNICAST_FLT for dwmac1000 bnx2x: Clear MDC/MDIO warning message bnx2x: Fix BCM57711+BCM84823 link issue bnx2x: Clear BCM84833 LED after fan failure bnx2x: Fix BCM84833 PHY FW version presentation bnx2x: Fix link issue for BCM8727 boards. ...

There exist more than one function for allocating and freeing the buffers: currently these 3 are used dma_{alloc, free}_coherent, dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent. For most of the systems these calls are almost equivalent and can be interchanged. For others, especially the truly non-coherent ones (like ARM), the difference can be easily noticed in overall driver performance. Sadly not all architectures provide implementations for all of them, so the drivers might need to be adapted and cannot be easily shared between different architectures. The provided patches unify all these functions and hide the differences under the already existing dma attributes concept. The thread with more references is available here: http://www.spinics.net/lists/linux-sh/msg09777.html These patches are also a prerequisite for unifying DMA-mapping implementation on ARM architecture with the common one provided by dma_map_ops structure and extending it with IOMMU support. More information is available in the following thread: http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819 More works on dma-mapping framework are planned, especially in the area of buffer sharing and managing the shared mappings (together with the recently introduced dma_buf interface: commit d15bd7ee445d "dma-buf: Introduce dma buffer sharing mechanism"). The patches in the current set introduce a new alloc/free methods (with support for memory attributes) in dma_map_ops structure, which will later replace dma_alloc_coherent and dma_alloc_writecombine functions." People finally started piping up with support for merging this, so I'm merging it as the last of the pending stuff from the merge window. Looks like pohmelfs is going to wait for 3.5 and more external support for merging. * 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: common: DMA-mapping: add NON-CONSISTENT attribute common: DMA-mapping: add WRITE_COMBINE attribute common: dma-mapping: introduce mmap method common: dma-mapping: remove old alloc_coherent and free_coherent methods Hexagon: adapt for dma_map_ops changes Unicore32: adapt for dma_map_ops changes Microblaze: adapt for dma_map_ops changes SH: adapt for dma_map_ops changes Alpha: adapt for dma_map_ops changes SPARC: adapt for dma_map_ops changes PowerPC: adapt for dma_map_ops changes MIPS: adapt for dma_map_ops changes X86 & IA64: adapt for dma_map_ops changes common: dma-mapping: introduce generic alloc() and free() methods

Its effect was to replace the use of the HLT instruction inside default_idle() with cpu_relax() - essentially it turned off the use of HLT. This workaround was commented in the code as: "disable hlt during certain critical i/o operations" "This halt magic was a workaround for ancient floppy DMA wreckage. It should be safe to remove." H. Peter Anvin additionally adds: "To the best of my knowledge, no-hlt only existed because of flaky power distributions on 386/486 systems which were sold to run DOS. Since DOS did no power management of any kind, including HLT, the power draw was fairly uniform; when exposed to the much hhigher noise levels you got when Linux used HLT caused some of these systems to fail. They were by far in the minority even back then." Alan Cox further says: "Also for the Cyrix 5510 which tended to go castors up if a HLT occurred during a DMA cycle and on a few other boxes HLT during DMA tended to go astray. Do we care ? I doubt it. The 5510 was pretty obscure, the 5520 fixed it, the 5530 is probably the oldest still in any kind of use." So, let's finally drop this.

This makes certain applications, like backup software, run much more quickly on buffered tape drives. Since legacy applications do not know about this new MTWEOFI ioctl, this patch adds a new ioctl option that tells the st driver to return immediately when writing an EOF (i.e. a filemark). This new flag is much like the existing flag that tells the st driver to perform writes (and certain other IOs) immediately, but this new flag only applies to writing EOFs. This new feature is controlled via the MTSETDRVBUFFER ioctl, using the newly-defined MT_ST_NOWAIT_EOF flag. Use of this new feature is displayed via the sysfs tape "options" attribute. The st documentation was updated to mention this new flag, as well as the problems that can occur from using it.
