HID: uhid: add internal message buffer
When receiving messages from the HID subsystem, we need to process them and store them in an internal buffer so user-space can read() on the char device to retrieve the messages. This adds a static buffer for 32 messages to each uhid device. Each message is dynamically allocated so the uhid_device structure does not get too big. uhid_queue() adds a message to the buffer. If the buffer is full, the message is discarded. uhid_queue_event() is an helper for messages without payload. This also adds a public header: uhid.h. It contains the declarations for the user-space API. It is built around "struct uhid_event" which contains a type field which specifies the event type and each event can then add a variable-length payload. For now, there is only a dummy event but later patches will add new event types and payloads. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> |

Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler changes from Ingo Molnar: "The biggest change is the cleanup/simplification of the load-balancer: instead of the current practice of architectures twiddling scheduler internal data structures and providing the scheduler domains in colorfully inconsistent ways, we now have generic scheduler code in kernel/sched/core.c:sched_init_numa() that looks at the architecture's node_distance() parameters and (while not fully trusting it) deducts a NUMA topology from it.

arm-soc: soc-specific pinctrl changes
With this, five platforms are moving to the relatively new pinctrl subsystem for their pin management, replacing the older soc specific in-kernel interfaces with common code. There is quite a bit of net addition of code for each platform being added to the pinctrl subsystem. but the payback comes later when adding new boards can be done by only providing new device trees instead. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJPuw1/AAoJEIwa5zzehBx3wbsP/RFCYzMVyz85BNLQuRyY9eO2 GCRWd0Vvy3fIfypiPdHdhkq6nIU/JnxgsfBbKX9FvWqvxXi96Ojh13KSIhSI1rQ9 t14VyuwUXaS3leeCyKxhNF1vRscz2iyEGXJqp+XEN4ckf2nrQCpKBiY5Eg9sH6/J fvYgSBY9Lf9nFAn+/wqSKIfdvw7H0NXwUdsLvNU0uCwvrSG929bTxx2AnHX00TdJ qf4XLhmatMg1uwdUgL/99ZxxgHlj6o55u7S6aRhUWXNXCimV6uEZ1F35ET37b+x3 YUltBCIaXjFR7iwNHmkkl42d8uyfkBznB555sY5qS3G/uF5Ma1R5I7fv8EIEy+2w bVHsva4lj1yFazic6m8yKTET4i8n6OPiKVNqGnDsp2yb6WzOGSliKdr0Jlo1oNG2 gS69LcDZxCkXrqEq0Ht8uUoCo9TWei+qhJ6ZOJ1Z3+9ZyFq1iRTKgPVxyA5VaHaB wwBbqKrohAwuExY8/gkAj6SYqBOF3l/J8QSB2JjXyj4trLC5UMq+l3L4cIWyMRPc fil83hV6460CiIBoKcsnV9hDUS0oh74mv52zHo0Xj73qABqZ4dcrpHVayWjtMtpl Z+tUpvD1rMQ+E0gdXDrwMrwILVyCDsBvpFKF4avnujDJ4WmyywtKZ+xvnpMd73VZ YrI/+XQsMT8ZfVkkj54D =HIfz -----END PGP SIGNATURE----- Merge tag 'pinctrl' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull arm soc-specific pinctrl changes from Olof Johansson: "With this, five platforms are moving to the relatively new pinctrl subsystem for their pin management, replacing the older soc specific in-kernel interfaces with common code.

arm-soc: support for new SoCs
Three new system-on-chip models are supported: the st-ericsson u9540 in ux500, the sam9n12 in at91 and the emma ev2 in shmobile. Emma is a little bit special because it is completely unrelated to the classic shmobile models, but the new Renesas rmobile SoCs are a combination of things from both Emma and shmobile, so it was decided to have them all live in one directory. This also contains updates to existing shmobile soc code as well as some related board changes due to dependencies. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJPuerfAAoJEIwa5zzehBx3hi4P/AsoiLW4VqN67zMmiaGC5Nwe X5nAeaaU0Oo4I9W2QD37V0BShk+yOE9xx7I0TOx7xE6/DpkJ3DhNlUOIvJSbtVD9 vOHF0pSu4huwmqMQmSS8qk5imYMVNGcDmNPVJsPdMCpC2PeCjNY5PxzX4PA18GxZ 9WaPClAP2vqSf/WewiFs73HE70TPL9DuMnAaA2QLBfeu6Cj5K401sc0sdJnBKJFc W7T8qo1LJ98wEWeGW1Qks2mhtwlRf3S20t6aYQi0Bm9znaHMRomdaWdkrXLUYxiO l8EHkCzgggXhdaqvqp15M3AFGgDsw+713UQ0n7tMGvIXv+Oc9ctriK0vcjIXHzH/ Ifz+4KvqYPo47ha0vSUpoRx29ThXO/zKDlzOUdh48JUWqBN6IDw+5H93ghI5SWGu 2h9RuAHIRxumtVe1Qb2dh2SzByxfqJJs7fkASXqWfucYgEi4vhylQdS7akCZ5ycq 35MOTS3v8rwxemTAR0NZKguRwVfUDnHGpyehumY5b/dp8nF0uHNaF8dRpnDC04Ty 4AHSquNmujQ0fqSJfcDCNT9V4vhrbdnW0YqhpCNFYLWBWnybJwjWDriWgt3Cc9tL BMApWGprknKjxH/LeoZHIr0cHGjhZ0iRgoX+av7mPbNUcW/T64HEIs1Yyo4dbE2w ffQN5xWomW+8VdZ1qf+w =5TAz -----END PGP SIGNATURE----- Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull support for new arm SoCs from Olof Johansson: "Three new system-on-chip models are supported: the st-ericsson u9540 in ux500, the sam9n12 in at91 and the emma ev2 in shmobile.

arm-soc: device tree conversions, part 1
The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of booting using device trees, which is a great step forward for them. at91 and spear have pretty much completed this process with a huge amount of work being put into at91. The other platforms are continuing the process. We finally start to see the payback on this investment, as new machines are getting supported purely by adding a .dts source file that can be completely independent of the kernel source. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJPueqRAAoJEIwa5zzehBx3AYkP/ibDGGd0qp1gxnxPYowliXcp lrWP8KB2PVcX/041jwpvsWeHzWT+Gm39ryBfz2L3pq/RiuU0jPPwChKgy1iglE8X 6Rq6sPWkXoDRtyeCuoiaxf1AYuzzAVdzZ0HlPO93tSKgo5eeyZRC5OeebAnrLDCE SDi8gZx2mm9+j2Dz46gq8QluyswMMbke3fHHHaHUlcP9fKIvFWvEfsn5j+YQ9bSw DrSIqGOzv6Emn7F6yhFQqxmk86KLnaXDVpAWgjVDhzaPv0rcTzloN6D2Ie2e5Vev BiRM1zvWn2d9kDk7gpm0t67nguYxsCBl1GNCP1brrncGwt15S10JimYlRhYW+B7u qgJqMPko3OnONvyl6e8qgIa2M5N4K/mo1i/jfOwFw3+KfUjXqLeio53Ysr4a6tsM Ev3bEsofNJKA0dlMcVzr7ntL087B6Y8mY3oJsVZji5M0KVfx1Jfn+X1W+l/2KD1H XWhJrCGa1HlbtSnrD+E91VHGC3M4sEXbbTljMAjHImlU9dGXmmbRMNsqNwkF6qFj EO2HnFvdN1oK+zEmeAttR1JHxfMdPFnTfmpUf3AiVSjGO//Wltelqx8ibA2Smn7S xXmzqX/HMhIOYCh81FdvzsK4qRYU5QyOsEJB4G0UjBZ66M1A3T/+vPpWuKsw5bUb qbnxaaXNsaZjWbbSSrZ4 =7DYv -----END PGP SIGNATURE----- Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull device tree conversions for arm-soc, part 1, from Olof Johansson: "The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of booting using device trees, which is a great step forward for them. at91 and spear have pretty much completed this process with a huge amount of work being put into at91.

arm-soc: First batch of cleanups
These cleanups are basically all over the place. The idea is to collect changes with minimal impact but large number of changes so we can avoid them from distracting in the diffstat in the other series. A significant number of lines get removed here, in particular because the ixp2000 and ixp23xx platforms get removed. These have never been extremely popular and have fallen into disuse over time with no active maintainer taking care of them. The u5500 soc never made it into a product, so we are removing it from the ux500 platform. Many good cleanups also went into the at91 and omap platforms, as has been the case for a number of releases. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJPuemiAAoJEIwa5zzehBx3L9oQAKiu0bsCiT6BM3VC5VGpluk7 YVLH/fkYGdSUTeGrpjeaoxxZnN5M1CLwErg3DxWcyYidy0zfmqitC8t2KQxZMxuf bt+hn4flpFnXMNm31B9xBCXOOVAvteZHYS35FdSKGyWo5Kz2WKM8ZrrihkAA7jVi U75x4+shFPtIhLNg2sJg4e/9D1T14ypElB7W989NzxMtco5fbukVd6vDBHPlFDG3 RVI2z2MbWUj3HVmdoyB+09ekruys0MQsbPOGo8D4aeJicrli/JBtL1r1w6ZZ6I8v Pe0+CbgemMWS69I37Zuxt35Bejpdofa8nKhT1jBrH4uHYxroKkhhx+VMTtuCcFVw Q2DhbbHImiW3598c0jkGi7Gk+TalTxkStMQiO3bqYAHApftdqFUgkpFSnOC/Jxgj Y6nUmd+GVPS+r0dDwZg4z5/AnUQd6t8Azp784muPDDxgTV1ZfdaC0LlLjdWesvMO x+PQib/U7NdxN5lifV6xCXpPoCQsgshrOkVUQiKVHmzaghm9MXgB8qrzXdTz3dLL XtR3+1KmSDTfHPSlTq/9vIN4RJtsKUnDWzNViTElEql36KzT7l5mJnBe6CJWirJh 7JNyH0p6XDZfc2q7LgdiSU0dv/j9LzBaYUukQCyUI3Tk+5zKgAdKbYNJpRcfPuoO BK6OKbjCAoAHL+/nDU2s =Hcjs -----END PGP SIGNATURE----- Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull first batch of arm-soc cleanups from Olof Johansson: "These cleanups are basically all over the place.

Posted to LKML: https://lkml.org/lkml/2012/4/23/322. 3) A couple of commits that improve the efficiency of the interaction between preemptible RCU and the scheduler, these two being all that survived an abortive attempt to allow preemptible RCU's __rcu_read_lock() to be inlined. The full set was posted to LKML at https://lkml.org/lkml/2012/4/14/143, and the first and third patches of that set remain. 4) Lai Jiangshan's algorithmic implementation of SRCU, which includes call_srcu() and srcu_barrier().

Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull scsi-target changes from Nicholas Bellinger: "There has been lots of work in existing code in a number of areas this past cycle. The major highlights have been: * Removal of transport_do_task_sg_chain() from core + fabrics (Roland) * target-core: Removal of se_task abstraction from target-core and enforce hw_max_sectors for pSCSI backends (hch) * Re-factoring of iscsi-target tx immediate/response queues (agrover) * Conversion of iscsi-target back to using target core memory allocation logic (agrover) We've had one last minute iscsi-target patch go into for-next to address a nasty regression bug related to the target core allocation logic conversion from agrover that is not included in friday's linux-next build, but has been included in this series. On the new fabric module code front for-3.5, here is a brief status update for the three currently in flight this round: * usb-gadget target driver: Sebastian Siewior's driver for supporting usb-gadget target mode operation. This will be going out as a separate PULL request from target-pending/usb-target-merge with subsystem maintainer ACKs. There is one minor target-core patch in this series required to function. * sbp ieee-1394/firewire target driver: Chris Boot's driver for supportting the Serial Block Protocol (SBP) across IEEE-1394 Firewire hardware. This will be going out as a separate PULL request from target-pending/sbp-target-merge with two additional drivers/firewire/ patches w/ subsystem maintainer ACKs. * qla2xxx LLD target mode infrastructure changes + tcm_qla2xxx: The Qlogic >= 24xx series HW target mode LLD infrastructure patch-set and tcm_qla2xxx fabric driver. Support for FC target mode using qla2xxx LLD code has been officially submitted by Qlogic to James below, and is currently outstanding but not yet merged into scsi.git/for-next.. [PATCH 00/22] qla2xxx: Updates for scsi "misc" branch http://www.spinics.net/lists/linux-scsi/msg59350.html Note there are *zero* direct dependencies upon this for-next series for the qla2xxx LLD target + tcm_qla2xxx patches submitted above, and over the last days the target mode team has been tracking down an tcm_qla2xxx specific active I/O shutdown bug that appears to now be almost squashed for 3.5-rc-fixes." * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (47 commits) iscsi-target: Fix iov_count calculation bug in iscsit_allocate_iovecs iscsi-target: remove dead code in iscsi_check_valuelist_for_support target: Handle ATA_16 passthrough for pSCSI backend devices target: Add MI_REPORT_TARGET_PGS ext. header + implict_trans_secs attribute target: Fix MAINTENANCE_IN service action CDB checks to use lower 5 bits target: add support for the WRITE_VERIFY command target: make target_put_session void target: cleanup transport_execute_tasks() target: Remove max_sectors device attribute for modern se_task less code target: lock => unlock typo in transport_lun_wait_for_tasks target: Enforce hw_max_sectors for SCF_SCSI_DATA_SG_IO_CDB target: remove the t_se_count field in struct se_cmd target: remove the t_task_cdbs_ex_left field in struct se_cmd target: remove the t_task_cdbs_left field in struct se_cmd target: remove struct se_task target: move the state and execute lists to the command target: simplify command to task linkage target: always allocate a single task target: replace ->execute_task with ->execute_cmd target: remove the task_sectors field in struct se_task ... |

regulator updates for 3.5
The major thing here is the addition of some helpers to factor code out of drivers, making a fair proportion of regulators much more just data rather than code which is nice. - Helpers in the core for regulators using regmap, providing generic implementations of the enable and voltage selection operations which just need data to describe them in the drivers. - Split out voltage mapping and voltage setting, allowing many more drivers to take advantage of the infrastructure for selectors. - Loads and loads of cleanups from Axel Lin once again, including many changes to take advantage of the above new framework features - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI TPS65913, TI TWL6035 and TI TWL6037. Some of the registration changes to support the core refactoring caused so many conflicts that eventually topic branches were abandoned for this release. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJPuhn4AAoJEBus8iNuMP3d6m4P/0gNiGbTwDlOgU/mPDyW2jJc xqvABzlOIQbI28/dgFYO/nA9YWW7VxpEaAPlkg4auk4wQ9tEyEjEqlOCfzymMetY 0k6L4n8LqFsbMAeNQbFPbW7PpWp59oI97J9afJI4kEJmHmOlmlL9U82/TzUFfGrA yiPlzue+DotKB7FjsymLMbLyeFoiMSOIjVDk8OTs0u1EqeOo4nJG2ODLa+yGo+QW 0yqQExEdIp28WXbkZQtmsOmj2V/uhkKAv2i2PDT2TmlduhNdCGxJsgZIiZCl1R4c vwirbfb+v93HAxvADdgj8eVdLJXQ0oItxr2ohKt8AgXIBrUJBsMkCQGvulZjRb+a /A/7Ea3o7HI+PQx4aIP0yGA/eBwbzo/cmBxU+KGzTA9Mov0fnK1kkUs6gfrYBdli U/TcMizDa1539BrKBIF2gmlRCKx8YD9ic27Zl1x4i5cgAP1gdYgdBYBybKHMpo2+ 9Xp1R9C8FvvgytIqJ3QQ34tRomZyQ5iUaIuIuAosoQ6iuF33EQ6I0FvHcIe74iOi zcu62ZPiuSwg1di9PrTERLcbrS81lvXpOWt5+EorzqoGXWzVIGoTh1F2kWEEMhaD Q6V5iE03VC0k3tj/MmtTiVkyhNkRElQDtekE9sfm15pdVnpu/+b+iicWJa7QFbZQ MybS0BBFQKhJXUDttKtS =UR7s -----END PGP SIGNATURE----- Merge tag 'regulator-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "The major thing here is the addition of some helpers to factor code out of drivers, making a fair proportion of regulators much more just data rather than code which is nice. - Helpers in the core for regulators using regmap, providing generic implementations of the enable and voltage selection operations which just need data to describe them in the drivers. - Split out voltage mapping and voltage setting, allowing many more drivers to take advantage of the infrastructure for selectors. - Loads and loads of cleanups from Axel Lin once again, including many changes to take advantage of the above new framework features - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI TPS65913, TI TWL6035 and TI TWL6037.

regmap: Updates for 3.5
A surprisingly large series of updates for regmap this time, mostly due to all the work Stephen Warren has done to add support for MMIO buses. This wasn't really the target for the framework but it turns out that there's a reasonable number of cases where it's very helpful to use the register cache support to allow the register map to remain available while the device is suspended. - A MMIO bus implementation, contributed by Stephen Warren. Currently this is limited to 32 bit systems and native endian registers. - Support for naming register maps, mainly intended for MMIO devices with multiple register banks. This was also contributed by Stephen Warren. - Support for register striding, again contributed by Stephen Warren and mainly intended for use with MMIO as typically the registers will be a fixed size but byte addressed. - irqdomain support for the generic regmap irq_chip, including support for dynamically allocate interrupt numbers. - A function dev_get_regmap() which allows frameworks using regmap to obtain the regmap for a device from the struct device, making life a little simpler for them. - Updates to regmap-irq to support more chips (contributed by Graeme Gregory) and to use irqdomains. - Support for devices with 24 bit register addresses. The striding support collided with all the topic branches so the branches look a bit messy and eventually I just gave up. There's also the TI Palmas driver and a couple of other isolated MFD patches that all depend on new regmap features so are being merged here. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJPtnhRAAoJEBus8iNuMP3d5yUQAJOHY+V9czTi87j6wRSOPJp+ JhTIpn5dgpe38gScGVxNXW9kvb+W/m9iVySvkWY4r79tGED8YjYQbof53mdilxww JhinDpUU4bSysgMCHJiVonOYwfeehBCuQhyk1DG4Fp7v8sc8sCFXo5HpdNMNDU+G QC0Dlo5kqceJY/miOdiprjKGcOLwZYtXb/c++CCfYbrQlg7+XdyDUcegQrDn3Tg9 ZIzl/cTuZJQ8FhewVR19ScmMA3pHaXXBWxuvdscEVPLIHoFi0Vbc/qFUUddEfA6Q g7wa5/hCOUnBTmCPdlt4fveXQllZSq5hj6cvLRuMtUFX9A1nqcYNUroLAnoJ9QVO 6JrCmvW6A8GxgMklf1aFvcOf3xoM0yQaTOy/bFzO52LHFV28bxcwG2572gLiMmn3 u8+z4voWy36kLDyUzwNzJ4vI1GjuyedPWSgXOX8D8S1UV1I0DeTrBEQEiVutJCP5 KsuGaYtmrXF20H7KnSufDYLTXMU/7hLMZhroNcglRKaYMf34A/kNGYHLb00JhrnC rWqPjGA+Wplj8IJXrZcALZqBODGcBL/jZR0+Uc1K03rnm5G/8O0IZqbwFIam0c/+ UDj/IrvoYliI2U3FdRS+MO+lN3+SK7OVvwP1qYROcmCsKt4R3FLLaPzLRXizrfHk JmlwCGWFIHu7jDtnUA6W =pjN4 -----END PGP SIGNATURE----- Merge tag 'regmap-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "A surprisingly large series of updates for regmap this time, mostly due to all the work Stephen Warren has done to add support for MMIO buses.

The last big thing here is my cleanup to the way we handle PCI across ARM, fixing some oddities in some platforms which hadn't realised there was a way to deal with their private data already built in to our PCI backend.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking changes from David Miller: 1) Get rid of the error prone NLA_PUT*() macros that used an embedded goto. 2) Kill off the token-ring and MCA networking drivers, from Paul Gortmaker. 3) Reduce high-order allocations made by datagram AF_UNIX sockets, from Eric Dumazet. 4) Add PTP hardware clock support to IGB and IXGBE, from Richard Cochran and Jacob Keller. 5) Allow users to query timestamping capabilities of a card via ethtool, from Richard Cochran. 6) Add loadbalance mode to the teaming driver, from Jiri Pirko. Part of this is that we can now have BPF filters not attached to sockets, and the loadbalancing function is calculated using one. 7) Francois Romieu went through the network drivers removing gratuitous uses of netdev->base_addr, perhaps some day we can remove it completely but it's used for ISA probing still. 8) Add a BPF JIT for sparc. I know, who cares, right? :-) 9) Move networking sysctl registry away from using the compatability mode interfaces in the sysctl code. From Eric W Biederman. 10) Pavel Emelyanov added a way to save and restore TCP socket state via TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as well as a way to forcefully bind a socket to a port via the sk->sk_reuse value SK_FORCE_REUSE. There is also a TCP_REPAIR_OPTIONS which allows to reinstante the TCP options enabled on the connection. 11) Several enhancements from Eric Dumazet that, in particular, can enhance splice performance on TCP sockets significantly. a) Reset the offset of the per-socket sendmsg page when we know we're the only use of the page in linear_to_page(). b) Add facilities such that skb->data can be backed a page rather than SLAB kmalloc'd memory. In particular devices which were receiving into linear RX buffers can now end up providing paged data. The big result is that code like splice and GRO do not have to copy any more. 12) Allow a pure sender to more gracefully handle ACK backlogs in TCP. What can happen at high rates is that the sender hasn't grown his receive buffer limits at all (he's not receiving data so really doesn't need to), but the non-data ACKs consume receive buffer space. sk_add_backlog() is too aggressive in dropping frames in this case, so relax it's requirements by using the receive buffer plus the send buffer limit as the backlog limit instead of just the former. Also from Eric Dumazet. 13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and Chris Elston. 14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng. Basically, we can start fast retransmit before hiting the dupack threshold under certain conditions. 15) New CODEL active queue management packet scheduler, from Eric Dumazet based upon initial work by Dave Taht. Basically, the big feature is that packets are dropped (or ECN bits are set) based upon how long packets live in the queue, rather than the queue length (which is what RED uses). * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1341 commits) drivers/net/stmmac: seq_file fix memory leak ipv6/exthdrs: strict Pad1 and PadN check USB: qmi_wwan: Add ZTE (Vodafone) K3520-Z USB: qmi_wwan: Add ZTE (Vodafone) K3765-Z USB: qmi_wwan: Make forced int 4 whitelist generic net/ipv4: replace simple_strtoul with kstrtoul net/ipv4/ipconfig: neaten __setup placement net: qmi_wwan: Add Vodafone/Huawei K5005 support net: cdc_ether: Add ZTE WWAN matches before generic Ethernet ipv6: use skb coalescing in reassembly ipv4: use skb coalescing in defragmentation net: introduce skb_try_coalesce() net:ipv6:fixed space issues relating to operators. net:ipv6:fixed a trailing white space issue. ipv6: disable GSO on sockets hitting dst_allfrag tg3: use netdev_alloc_frag() API net: napi_frags_skb() is static ppp: avoid false drop_monitor false positives ipv6: bool/const conversions phase2 ipx: Remove spurious NULL checking in ipx_ioctl(). ... |

Merge branch 'dentry-cleanups' (dcache access cleanups and optimizations)
This branch simplifies and clarifies the dcache lookup, and allows us to do certain nice optimizations when comparing dentries. It also cleans up the interface to __d_lookup_rcu(), especially around passing the inode information around. * dentry-cleanups: vfs: make it possible to access the dentry hash/len as one 64-bit entry vfs: move dentry name length comparison from dentry_cmp() into callers vfs: do the careful dentry name access for all dentry_cmp cases vfs: remove unnecessary d_unhashed() check from __d_lookup_rcu vfs: clean up __d_lookup_rcu() and dentry_cmp() interfaces |

Merge branch 'vm-cleanups' (unmap_vma() interface cleanup)
This series sanitizes the interface to unmap_vma(). The crazy interface annoyed me no end when I was looking at unmap_single_vma(), which we can spend quite a lot of time in (especially with loads that have a lot of small fork/exec's: shell scripts etc). Moving the nr_accounted calculations to where they belong at least clarifies things a little. I hope to come back to look at the performance of this later, but if/when I get back to it I at least don't have to see the crazy interfaces any more. * vm-cleanups: vm: remove 'nr_accounted' calculations from the unmap_vmas() interfaces vm: simplify unmap_vmas() calling convention |

isci update for 3.5
1/ Rework remote-node-context (RNC) handling for proper management of the silicon state machine in error handling and hot-plug conditions. Further details below, suffice to say if the RNC is mismanaged the silicon state machines may lock up. 2/ Refactor the initialization code to be reused for suspend/resume support 3/ Miscellaneous bug fixes to address discovery issues and hardware compatibility. RNC rework details from Jeff Skirvin: In the controller, devices as they appear on a SAS domain (or direct-attached SATA devices) are represented by memory structures known as "Remote Node Contexts" (RNCs). These structures are transferred from main memory to the controller using a set of register commands; these commands include setting up the context ("posting"), removing the context ("invalidating"), and commands to control the scheduling of commands and connections to that remote device ("suspensions" and "resumptions"). There is a similar path to control RNC scheduling from the protocol engine, which interprets the results of command and data transmission and reception. In general, the controller chooses among non-suspended RNCs to find one that has work requiring scheduling the transmission of command and data frames to a target. Likewise, when a target tries to return data back to the initiator, the state of the RNC is used by the controller to determine how to treat the incoming request. As an example, if the RNC is in the state "TX/RX Suspended", incoming SSP connection requests from the target will be rejected by the controller hardware. When an RNC is "TX Suspended", it will not be selected by the controller hardware to start outgoing command or data operations (with certain priority-based exceptions). As mentioned above, there are two sources for management of the RNC states: commands from driver software, and the result of transmission and reception conditions of commands and data signaled by the controller hardware. As an example of the latter, if an outgoing SSP command ends with a OPEN_REJECT(BAD_DESTINATION) status, the RNC state will transition to the "TX Suspended" state, and this is signaled by the controller hardware in the status to the completion of the pending command as well as signaled in a controller hardware event. Examples of the former are included in the patch changelogs. Driver software is required to suspend the RNC in a "TX/RX Suspended" condition before any outstanding commands can be terminated. Failure to guarantee this can lead to a complete hardware hang condition. Earlier versions of the driver software did not guarantee that an RNC was correctly managed before I/O termination, and so operated in an unsafe way. Further, the driver performed unnecessary contortions to preserve the remote device command state and so was more complicated than it needed to be. A simplifying driver assumption is that once an I/O has entered the error handler path without having completed in the target, the requirement on the driver is that all use of the sas_task must end. Beyond that, recovery of operation is dependent on libsas and other components to reset, rediscover and reconfigure the device before normal operation can restart. In the driver, this simplifying assumption meant that the RNC management could be reduced to entry into the suspended state, terminating the targeted I/O request, and resuming the RNC as needed for device-specific management such as an SSP Abort Task or LUN Reset Management request. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJPtYFXAAoJEB7SkWpmfYgCJkcP/1VvsuuitNy/YM9P1tb/RvQ7 ytJzjGtWiAABHVWwjgB+Ng7hUTaP2r6l8KeNfwxpwXyNdBAUNysYEUBHAfPsKzKz espTmw3wVCnREajgKXZwFp9aTj8DcYFB6vKcC/ddACt3uRNjjA9En36+6797r8Vg YdebyjFX2FxwoUj0icTUiV/OXgb8w723imnCl8bfOhhFRi4eFZ4EJ23AdMkUya1i uYePAPJPSQJuU/87gNIx4JcR0qHJ1ziGPEY+XC47CzEeXbBTSPgWOwanQ6KPoXRJ XVxamfcKAjRdtwQ4m1vYBSE32RTdrjhujVbkGiPi6QaEbCLjhLSCIYyuS3XMckV+ TCZ16o5kd/I6ZtZOeP4zZRGnNBkOPzY44qiJeKffjWDhTrFacx4XWJB/ftWPgEA5 N2zFH3RM4sY0FUJ3I/Qe5CERNdCXMtcj+UAf3nHpAIVcv46Lp+qoSkdEx05uuuiN +D/dSlubktuvuzmB5WisL3qrjNEkkLTAGQpZs1j0ojLEBm0XAgV5EzqmHiZ0GOPD OQNFxeei9SlqgtKIIP0bymRispPrG2HVCOvExYMxzKR6fjxofZLAs/aWOsdhxgMq TlAyZJ6OmGI+KX68HHzoMpT9iquvmP64WGkfHzCx296BfSKiruLh/Jzt5gGwv+Z1 5tlpnUr9dUTxx7qkQXvj =HYvO -----END PGP SIGNATURE----- Merge tag 'isci-for-3.5' into misc isci update for 3.5 1/ Rework remote-node-context (RNC) handling for proper management of the silicon state machine in error handling and hot-plug conditions.

net: introduce skb_try_coalesce()
Move tcp_try_coalesce() protocol independent part to skb_try_coalesce(). skb_try_coalesce() can be used in IPv4 defrag and IPv6 reassembly, to build optimized skbs (less sk_buff, and possibly less 'headers') skb_try_coalesce() is zero copy, unless the copy can fit in destination header (its a rare case) kfree_skb_partial() is also moved to net/core/skbuff.c and exported, because IPv6 will need it in patch (ipv6: use skb coalescing in reassembly).
