  1. Merge tag 'nfs-for-3.7-4' of git://git.linux-nfs.org/projects/trondmy…

    …/linux-nfs
    
    Pull NFS client bugfixes from Trond Myklebust:
    
     - Fix a bunch of deadlock situations:
       * State recovery can deadlock if we fail to release sequence ids
         before scheduling the recovery thread.
       * Calling deactivate_super() from an RPC workqueue thread can
         deadlock because of the call to rpc_shutdown_client.
    
     - Display the device name correctly in /proc/*/mounts
    
     - Fix a number of incorrect error return values:
       * When NFSv3 mounts fail due to a timeout.
       * On NFSv4.1 backchannel setup failure
       * On NFSv4 open access checks
    
     - pnfs_find_alloc_layout() must check the layout pointer for NULL
    
     - Fix a regression in the legacy DNS resolved
    
    * tag 'nfs-for-3.7-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs:
      NFS4: nfs4_opendata_access should return errno
      NFSv4: Initialise the NFSv4.1 slot table highest_used_slotid correctly
      SUNRPC: return proper errno from backchannel_rqst
      NFS: add nfs_sb_deactive_async to avoid deadlock
      nfs: Show original device name verbatim in /proc/*/mount{s,info}
      nfsv3: Make v3 mounts fail with ETIMEDOUTs instead EIO on mountd timeouts
      nfs: Check whether a layout pointer is NULL before free it
      NFS: fix bug in legacy DNS resolver.
      NFSv4: nfs4_locku_done must release the sequence id
      NFSv4.1: We must release the sequence id when we fail to get a session slot
      NFS: Wait for session recovery to finish before returning

  2. Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/g…

    …it/rzhang/linux
    
    Pull thermal management & ACPI update from Zhang Rui,
    
    Ho humm.  Normally these things go through Len.  But it's just three
    small fixes, I guess I can pull directly too.

    …it/wsa/linux
    
    Pull i2c embedded fixes from Wolfram Sang:
     "Two patches are usual stuff.
    
      The bigger patch is needed to correct a wrong decision made in this
      merge window.  We hoped to get the PIOQUEUE mode in the mxs driver
      working with DMA, but it turned out to be too broken (leading to data
      loss), so we now think it is best to remove it entirely and work only
      with DMA now.  The patch should be in 3.7.  IMO, so users never get
      the chance to use both modes in parallel."

  6. tcp-repair: Handle zero-length data put in rcv queue

    When sending data into a tcp socket in repair state we should check
    for the amount of data being 0 explicitly. Otherwise we'll have an skb
    with seq == end_seq in rcv queue, but tcp doesn't expect this to happen
    (in particular a warn_on in tcp_recvmsg shoots).

  7. vmxnet3: must split too big fragments

    vmxnet3 has a 16Kbytes limit per tx descriptor, that happened to work
    as long as we provided PAGE_SIZE fragments.
    
    Our stack can now build larger fragments, so we need to split them to
    the 16kbytes boundary.

  8. l2tp: fix oops in l2tp_eth_create() error path

    When creating an L2TPv3 Ethernet session, if register_netdev() should fail for
    any reason (for example, automatic naming for "l2tpeth%d" interfaces hits the
    32k-interface limit), the netdev is freed in the error path.  However, the
    l2tp_eth_sess structure's dev pointer is left uncleared, and this results in
    l2tp_eth_delete() then attempting to unregister the same netdev later in the
    session teardown.  This results in an oops.
    
    To avoid this, clear the session dev pointer in the error path.

    	Subject: frv: split ret_from_fork, simplify kernel_thread() a lot
    
    The problem is that the userspace registers are completely cleared when a
    kernel thread is created and all subsequent user threads are then copied from
    that.  Unfortunately, however, the TBR and PSR registers are restored from the
    pt_regs and the values they should be set to are clobbered by the memset.
    
    Instead, copy across the old user registers as normal, and then merely alter
    GR8 and GR9 in it if we're going to execute a kernel thread.

  12. FRV: Fix the preemption handling

    Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is
    incorrectly loaded into the threadinfo flags rather than the threadinfo
    preemption count.
    
    Unfortunately, the code cannot be simply converted to use
    preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to
    cut down on the cost of actually disabling interrupts and thus
    local_irq_enable() doesn't actually enable interrupts.

  13. FRV: gcc-4.1.2 also inlines weak functions

    gcc-4.1.2 inlines weak functions, which causes FRV to fail when the dummy
    thread_info_cache_init() gets inlined into start_kernel().

  14. FRV: Don't objcopy the GNU build_id note

    Don't let objcopy transfer the GNU build_id note into the loadable image as it
    is located at address 0 and the image ends up >3G in size.

  16. i2c: tegra: set irq name as device name

    When watching the irqs name of tegra i2c, all instances
    irq name shows as tegra_i2c.
    
    Passing the device name properly to have the irq names with
    instance like tegra-i2c.0, tegra-i2c.1 etc.

  18. i2c: mxs: remove broken PIOQUEUE support

    This I2C master can do DMA and PIOQUEUE (PIO with FIFO). Originally,
    only PIOQUEUE was supported and it had issues, then DMA support was added
    this cycle. The original intention was to keep PIOQUEUE since it has
    less overhead what is nice for small transfers. However, runtime
    switching between PIOQEUE and DMA depending on the transfer size never
    worked despite a lot of trying. Since PIOQUEUE mode itself was flaky
    (polling at places where interrupts failed to work) and the
    implementation also imposed a size limit for transfers, it is best to
    remove the support, so users don't fall over its limitations. It also
    makes the driver a lot cleaner and more robust. If somebody really wants
    less overhead, plain PIO mode could still be implemented with the
    addidtional advantage that this mode is also available on MX23, too.

     "Some important bug fixes.
    
      With the change to uapi, there was a bug introduced that results in an
      empty syscall table (mult-inclusion bug).  Switching to the generic
      thread/execve allowed us to fix a bug we had in vfork()."
