2013-12-06virtio-net: determine type of bufs correctlyAndrey Vagin
free_unused_bufs must check vi->mergeable_rx_bufs before vi->big_packets, because we use this sequence in other places.

Write-combine and cacheable mappings use Normal memory on arm64. On SMP systems, the pte needs the shareability bit which is set in pgprot_default.

2013-12-06arm64: kernel: add code to set cpu boot mode to secondary_entry shimLorenzo Pieralisi
The refactoring of el2_setup split code setting up EL2 and detecting the CPU boot mode in separate chunks. This allows the code that sets up EL2 to run in an endian independent way - ie before the endianess is set up in the respective sctlr registers. This patch brings secondary_entry up-to-date so that CPUs entering the kernel through this code path set-up EL2 and the cpu boot mode properly.

2013-12-06arm64: ensure completion of TLB invalidatationMark Rutland
Currently there is no dsb between the tlbi in __cpu_setup and the write to SCTLR_EL1 which enables the MMU in __turn_mmu_on. This means that the TLB invalidation is not guaranteed to have completed at the point address translation is enabled, leading to a number of possible issues including incorrect translations and TLB conflict faults. This patch moves the tlbi in __cpu_setup above an existing dsb used to synchronise I-cache invalidation, ensuring that the TLBs have been invalidated at the point the MMU is enabled.

2013-12-06iommu/arm-smmu: use mutex instead of spinlock for locking page tablesWill Deacon
When creating IO mappings, we lazily allocate our page tables using the standard, non-atomic allocator functions. This presents us with a problem, since our page tables are protected with a spinlock. This patch reworks the smmu_domain lock to use a mutex instead of a spinlock. iova_to_phys is then reworked so that it only reads the page tables, and can run in a lockless fashion, leaving the mutex to guard against concurrent mapping threads.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "A regression showed up that there's a large delay when enabling all events. This was prevalent when FTRACE_SELFTEST was enabled which enables all events several times, and caused the system bootup to pause for over a minute. This was tracked down to an addition of a synchronize_sched() performed when system call tracepoints are unregistered. The synchronize_sched() is needed between the unregistering of the system call tracepoint and a deletion of a tracing instance buffer. But placing the synchronize_sched() in the unreg of *every* system call tracepoint is a bit overboard. A single synchronize_sched() before the deletion of the instance is sufficient" * tag 'trace-fixes-3.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Only run synchronize_sched() at instance deletion time

2013-12-05tcp_memcontrol: Cleanup/fix cg_proto->memory_pressure handling.Eric W. Biederman
kill memcg_tcp_enter_memory_pressure. The only function of memcg_tcp_enter_memory_pressure was to reduce deal with the unnecessary abstraction that was tcp_memcontrol. Now that struct tcp_memcontrol is gone remove this unnecessary function, the unnecessary function pointer, and modify sk_enter_memory_pressure to set this field directly, just as sk_leave_memory_pressure cleas this field directly. This fixes a small bug I intruduced when killing struct tcp_memcontrol that caused memcg_tcp_enter_memory_pressure to never be called and thus failed to ever set cg_proto->memory_pressure. Remove the cg_proto enter_memory_pressure function as it now serves no useful purpose. Don't test cg_proto->memory_presser in sk_leave_memory_pressure before clearing it. The test was originally there to ensure that the pointer was non-NULL. Now that cg_proto is not a pointer the pointer does not matter. Signed-off-by: "Eric W.

2013-12-05net: davinci_emac: Fix platform data handling and make usable for am3517Tony Lindgren
When booted with device tree, we may still have platform data passed as auxdata. For am3517 this is needed for passing the interrupt_enable and interrupt_disable callbacks that access the omap system control module registers. These callback functions will eventually go away when we have a separate system control module driver. Some of the things that are currently passed as platform data we don't need to set up as device tree properties as they are always the same on am3517. So let's use a new compatible flag for those so we can get those from the device tree match data. Also note that we need to fix setting of phy_dev to NULL instead of an empty string as the code later on uses that to find the first phy on the mdio bus.

Pull block layer fixes from Jens Axboe: "A small collection of fixes for the current series. It contains: - A fix for a use-after-free of a request in blk-mq. From Ming Lei - A fix for a blk-mq bug that could attempt to dereference a NULL rq if allocation failed - Two xen-blkfront small fixes - Cleanup of submit_bio_wait() type uses in the kernel, unifying that. From Kent - A fix for 32-bit blkg_rwstat reading. I apologize for this one looking mangled in the shortlog, it's entirely my fault for missing an empty line between the description and body of the text" * 'for-linus' of git://git.kernel.dk/linux-block: blk-mq: fix use-after-free of request blk-mq: fix dereference of rq->mq_ctx if allocation fails block: xen-blkfront: Fix possible NULL ptr dereference xen-blkfront: Silence pfn maybe-uninitialized warning block: submit_bio_wait() conversions Update of blkg_stat and blkg_rwstat may happen in bh context

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== Please pull this batch of fixes intende for the 3.13 stream! For the mac80211 bits, Johannes says: "For now I have various fixes all over, mostly for issues introduced in relatively recent patches. There's no real pattern to it. Some of the issues like go back longer, but still seemed 3.13 material." And... "These are just two patches disabling the broken CSA code. Once this goes into your tree I'll merge it into mac80211-next and revert there (since we fixed the bugs there)." For the iwlwifi bits, Emmanuel says: "I have here a few fixes for BT Coex. One of them is a NULL pointer dereference. Another one avoids to enable a feature that can make the firmware unhappy since the firmware isn't ready for it yet. WE also avoid a WARNING that can be triggered upon association in not-so-bad cases even if the association succeeded. We add support for new NICs (not yet on the market) and bump the API so that 3.13 will be able to work with the new firmware that will be out soon hopefully. I also have a boundary check from Johannes." In addition to those... - Arend van Spriel fixes a brcmfmac problem that could use an uninitialized variable in an error path. - Borislav Petkov fixes a Kconfig-based build breakage problem for brcmsmac. - Michal Nazarewicz fixes a couple of NULL pointer dereference problems in ath9k and wcn36xx. - Sujith Manoharan fixes a couple of ath9k problems related to incorrect interpretation of EEPROM configuration data. - Ujjal Roy fixes a memory leak in mwifiex. ==================== Signed-off-by: David S.

2013-12-05Input: ALPS - add support for DualPoint device on Dell XT2 modelYunkang Tang
The device uses special MPU controller that necessitates the new initialization sequence for the device. We also define a new protocol for the trackpad that allows reporting better resolution than older V2 protocol.
