2012-08-03ACPI processor: Fix tick_broadcast_mask online/offline regressionFeng Tang
In commit 99b725084 "ACPI processor hotplug: Delay acpi_processor_start() call for hotplugged cores", acpi_processor_hotplug(pr) was wrongly replaced by acpi_processor_cst_has_changed() inside the acpi_cpu_soft_notify(). This patch will restore it back, fixing the tick_broadcast_mask regression: https://lkml.org/lkml/2012/7/30/169 Signed-off-by: Feng Tang <feng.tang@intel.com> Cc: Thomas Renninger <trenn@suse.de> Cc: <stable@vger.kernel.org> # 3.3+ Reviewed-by: Rafael J.

On an OLPC XO-1.5 we have seen the following situation: - the system starts going into suspend - no wake params are set, so the mmc layer removes the card - during remove, we send a command to the card - that command fails, causing if_sdio's reset method to try and remove the mmc card in attempt to reset it - the mmc layer is not happy about being asked to remove a card that it is already removing, and the kernel crashes While the MMC layer could possibly be taught to behave better here, it also seems sensible for libertas not to try and reset a card if we're in the process of removing it anyway.

2012-08-02cfg80211: add channel flag to prohibit OFDM operationSeth Forshee

This patch adds a new flag, IEEE80211_CHAN_NO_OFDM, to tell drivers that OFDM on a channel is not allowed. This flag is set on any channels for which regulatory indicates that OFDM is prohibited.

It is very common for the end of the file to be unaligned on stripe size. But since we know it's beyond file's end then the XOR should be preformed with all zeros. Old code used to just read zeros out of the OSD devices, which is a great waist. But what scares me more about this situation is that, we now have pages attached to the file's mapping that are beyond i_size. I don't like the kind of bugs this calls for.

2012-08-02sfc: Fix maximum number of TSO segments and minimum TX queue sizeBen Hutchings
Currently an skb requiring TSO may not fit within a minimum-size TX queue. The TX queue selected for the skb may stall and trigger the TX watchdog repeatedly (since the problem skb will be retried after the TX reset). This issue is designated as CVE-2012-3412. Set the maximum number of TSO segments for our devices to 100. This should make no difference to behaviour unless the actual MSS is less than about 700. Increase the minimum TX queue size accordingly to allow for 2 worst-case skbs, so that there will definitely be space to add an skb after we wake a queue. To avoid invalidating existing configurations, change efx_ethtool_set_ringparam() to fix up values that are too small rather than returning -EINVAL.

2012-08-02net: Allow driver to limit number of GSO segments per skbBen Hutchings
A peer (or local user) may cause TCP to use a nominal MSS of as little as 88 (actual MSS of 76 with timestamps). Given that we have a sufficiently prodigious local sender and the peer ACKs quickly enough, it is nevertheless possible to grow the window for such a connection to the point that we will try to send just under 64K at once. This results in a single skb that expands to 861 segments. In some drivers with TSO support, such an skb will require hundreds of DMA descriptors; a substantial fraction of a TX ring or even more than a full ring. The TX queue selected for the skb may stall and trigger the TX watchdog repeatedly (since the problem skb will be retried after the TX reset). This particularly affects sfc, for which the issue is designated as CVE-2012-3412. Therefore: 1. Add the field net_device::gso_max_segs holding the device-specific limit. 2. In netif_skb_features(), if the number of segments is too high then mask out GSO features to force fall back to software GSO.

Pull MIPS updates from Ralf Baechle: "The lion share of this pull request are fixes for clk-related breakage caused by other changes during this merge window. For some platforms the fix was as simple as selecting HAVE_CLK, for others like the Loongson 2 significant restructuring was required. The remainder are changes required to get the Lantiq code to work again." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Loongson 2: Sort out clock managment.

2012-08-01Merge branch 'dmaengine' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull ARM DMA engine updates from Russell King: "This looks scary at first glance, but what it is is: - a rework of the sa11x0 DMA engine driver merged during the previous cycle, to extract a common set of helper functions for DMA engine implementations. - conversion of amba-pl08x.c to use these helper functions. - addition of OMAP DMA engine driver (using these helper functions), and conversion of some of the OMAP DMA users to use DMA engine. Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."
