      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.
      
        Some of the registration changes to support the core refactoring
        caused so many conflicts that eventually topic branches were abandoned
        for this release."

      Linus Torvalds authored
      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.  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."

      vfs: be even more careful about dentry RCU name lookups · 6326c71f
      Linus Torvalds authored
      Miklos Szeredi points out that we need to also worry about memory
      odering when doing the dentry name comparison asynchronously with RCU.
      
      In particular, doing a rename can do a memcpy() of one dentry name over
      another, and we want to make sure that any unlocked reader will always
      see the proper terminating NUL character, so that it won't ever run off
      the allocation.
      
      Rather than having to be extra careful with the name copy or at lookup
      time for each character, this resolves the issue by making sure that all
      names that are inlined in the dentry always have a NUL character at the
      end of the name allocation.  If we do that at dentry allocation time, we
      know that no future name copy will ever change that final NUL to
      anything else, so there are no memory ordering issues.
      
      So even if a concurrent rename ends up overwriting the NUL character
      that terminates the original name, we always know that there is one
      final NUL at the end, and there is no worry about the lockless RCU
      lookup traversing the name too far.
      
      The out-of-line allocations are never copied over, so we can just make
      sure that we write the name (with terminating NULL) and do a write
      barrier before we expose the name to anything else by setting it in the
      dentry.

      vfs: make AIO use the proper rw_verify_area() area helpers · a70b52ec
      Linus Torvalds authored
      We had for some reason overlooked the AIO interface, and it didn't use
      the proper rw_verify_area() helper function that checks (for example)
      mandatory locking on the file, and that the size of the access doesn't
      cause us to overflow the provided offset limits etc.
      
      Instead, AIO did just the security_file_permission() thing (that
      rw_verify_area() also does) directly.
      
      This fixes it to do all the proper helper functions, which not only
      means that now mandatory file locking works with AIO too, we can
      actually remove lines of code.

       "This is the bulk of the core ARM updates for this merge window.
        Included in here is a different way to handle the VIVT cache flushing
        on context switch, which should allow scheduler folk to remove a
        special case in their core code.
      
        We have architectured timer support here, which is a set of timers
        specified by the ARM architecture for future SoCs.  So we should see
        less variability in timer design going forward.
      
        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.
      
        I've also removed support for the ARMv3 architecture; it hasn't worked
        properly for years so it seems pointless to keep it around."

      Fix blocking allocations called very early during bootup · 31a67102
      Linus Torvalds authored
      During early boot, when the scheduler hasn't really been fully set up,
      we really can't do blocking allocations because with certain (dubious)
      configurations the "might_resched()" calls can actually result in
      scheduling events.
      
      We could just make such users always use GFP_ATOMIC, but quite often the
      code that does the allocation isn't really aware of the fact that the
      scheduler isn't up yet, and forcing that kind of random knowledge on the
      initialization code is just annoying and not good for anybody.
      
      And we actually have a the 'gfp_allowed_mask' exactly for this reason:
      it's just that the kernel init sequence happens to set it to allow
      blocking allocations much too early.
      
      So move the 'gfp_allowed_mask' initialization from 'start_kernel()'
      (which is some of the earliest init code, and runs with preemption
      disabled for good reasons) into 'kernel_init()'.  kernel_init() is run
      in the newly created thread that will become the 'init' process, as
      opposed to the early startup code that runs within the context of what
      will be the first idle thread.
      
      So by the time we reach 'kernel_init()', we know that the scheduler must
      be at least limping along, because we've already scheduled from the idle
      thread into the init thread.

      also for future "selectable" config symbols.
      
      Fix up all users to drop the dependency on NET now that it is not

      Pull sparc updates from David Miller:
      
      1) Kill off support for sun4c and Cypress sun4m chips.
      
         And as a result we were able to also kill off that ugly btfixup thing
         that required multi-stage links of the final vmlinux image in the
         Kbuild system.  This should make the kbuild maintainers really happy.
      
         Thanks a lot to Sam Ravnborg for his tireless efforts to get this
         going.
      
      2) Convert sparc64 to nobootmem.  I suspect now with sparc32 being a lot
         cleaner, it should be able to fall in line and modernize in this area
         too.
      
      3) Make sparc32 use generic clockevents, from Tkhai Kirill.
      
      [ I fixed up the BPF rules, and tried to clean up the build rules too.
        But I don't have - or want - a sparc cross-build environment, so the
        BPF rule bug and the related build cleanup was all done with just a
        bare "make -n" pseudo-test.      - Linus ]

      Linus Torvalds authored
      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).

      Merge branch 'vfs-cleanups' (random vfs cleanups) · 7e5cb5e1
      Linus Torvalds authored
      This teaches vfs_fstat() to use the appropriate f[get|put]_light
      functions, allowing it to avoid some unnecessary locking for the common
      case.
      
      More noticeably, it also cleans up and simplifies the "getname_flags()"
      function, which now relies on the architecture strncpy_from_user() doing
      all the user access checks properly, instead of hacking around the fact
      that on x86 it didn't use to do it right (see commit 92ae03f2: "x86:
      merge 32/64-bit versions of 'strncpy_from_user()' and speed it up").
      
      * vfs-cleanups:
        VFS: make vfs_fstat() use f[get|put]_light()
        VFS: clean up and simplify getname_flags()
        x86: make word-at-a-time strncpy_from_user clear bytes at the end

      Linus Torvalds authored
      This makes cp_new_stat() a bit more readable, and avoids having to
      memset() the whole structure just to fill in a couple of padding fields.
      
      This is another result of me looking at code generation of functions
      that show up high on certain kernel profiles, and just going "Oh, let's
      just clean that up".
      
      Architectures that don't supply the #define to fill just the padding
      fields will still fall back to memset().
      
      * stat-cleanups:
        vfs: don't force a big memset of stat data just to clear padding fields
        vfs: de-crapify "cp_new_stat()" function

      Merge branch 'vm-cleanups' (unmap_vma() interface cleanup) · dddbd541
      Linus Torvalds authored
      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
