      NFS: Ensure that setattr and getattr wait for O_DIRECT write completion · 1d59d61f
      Trond Myklebust authored
      Use the same mechanism as the block devices are using, but move the
      helper functions from fs/direct-io.c into fs/inode.c to remove the
      dependency on CONFIG_BLOCK.

      Pull Sparc updates from David S. Miller:
      
       1) Remove the idiotic situation wherein Leon was a special case in all
          of the TLB/cache handling code.
      
          The worst side effect of this bogosity is that you couldn't build a
          kernel with Leon support enabled (to get better build coverage), and
          test boot it on a non-LEON cpu.
      
          Leon is, in all core respects, programatically identical to the
          32-bit SRMMU.  Except that they put the TLB registers in a different
          alternate address space location.
      
          Through code patching (for fast paths) and run time checks, this
          issue is now a thing of the past.
      
          From Sam Ravnborg.
      
       2) There was a mis-merge of arch/sparc/Kconfig for one of the
          clockevents changes that went in, causing 32-bit sparc to start
          failing to build.
      
          I merged in your tree to get those clockevents changes (and added a
          note to the merge commit) then added Stephen Rothwell's fix for the
          merge error.
      
       3) Software quad floating point emulation was not working properly on
          more recent Niagara chips, because the way the situation is reported
          by the cpu has changed.
      
          Nobody noticed because gcc emits calls to software emulation
          routines in glibc.

      ARM: LPC32xx: Adjust dts files to gpio dt binding · a035254a
      Roland Stigge authored
      The GPIO devicetree binding in 3.5 doesn't register the various LPC32xx GPIO
      banks via DT subnodes but always all at once, and changes the gpio referencing
      to 3 cells (bank, gpio, flags). This patch adjusts the DTS files to this
      binding that was just accepted to the gpio subsystem.

      Lee Jones authored
      Current failure paths attempt to free resources which we failed to request
      and disable resources which we failed to enable ones. This leads to kernel
      oops/panic. This patch does some simple re-ordering to prevent this from
      happening.

      virtio-net: remove useless disable on freeze · 3bbf372c
      Michael S. Tsirkin authored
      disable_cb is just an optimization: it
      can not guarantee that there are no callbacks.
      In particular it doesn't have any effect when
      event index is on.
      
      Instead, detach, napi disable and reset on freeze ensure we don't run
      concurrently with a callback.
      
      Remove the useless calls so we get same behaviour

      mm: fix vma_resv_map() NULL pointer · 4523e145

      hugetlb_reserve_pages() can be used for either normal file-backed
      hugetlbfs mappings, or MAP_HUGETLB.  In the MAP_HUGETLB, semi-anonymous
      mode, there is not a VMA around.  The new call to resv_map_put() assumed
      that there was, and resulted in a NULL pointer dereference:

      John Dykstra authored
      Function pat_pagerange_is_ram() scales poorly to large address
      ranges, because it probes the resource tree for each page.
      
      On a 2.6 GHz Opteron, this function consumes 34 ms for a 1 GB range.
      
      It is called twice during untrack_pfn_vma(), slowing process
      cleanup and handicapping the OOM killer.
      
      This replacement consumes less than 1ms, under the same conditions.

      i2c: Split I2C_M_NOSTART support out of I2C_FUNC_PROTOCOL_MANGLING · 14674e70
      Mark Brown authored
      Since there are uses for I2C_M_NOSTART which are much more sensible and
      standard than most of the protocol mangling functionality (the main one
      being gather writes to devices where something like a register address
      needs to be inserted before a block of data) create a new I2C_FUNC_NOSTART
      for this feature and update all the users to use it.
      
      Also strengthen the disrecommendation of the protocol mangling while we're
      at it.
      
      In the case of regmap-i2c we remove the requirement for mangling as
      I2C_M_NOSTART is the only mangling feature which is being used.

      i2c-dev: Add support for I2C_M_RECV_LEN · 838bfa60
      Jean Delvare authored
      As the bus driver side implementation of I2C_M_RECV_LEN is heavily
      tied to SMBus, we can't support received length over 32 bytes, but
      let's at least support that.
      
      In practice, the caller will have to setup a buffer large enough to
      cover the case where received length byte has value 32, so minimum
      32 + 1 = 33 bytes, possibly more if there is a fixed number of bytes
      added for the specific slave (for example a checksum.)
