      x86/kallsyms: fix GOLD link failure with new relative kallsyms table format · 142b9e6c
      Ard Biesheuvel authored
      Commit 2213e9a6 ("kallsyms: add support for relative offsets in
      kallsyms address table") changed the default kallsyms symbol table
      format to use relative references rather than absolute addresses.
      
      This reduces the size of the kallsyms symbol table by 50% on 64-bit
      architectures, and further reduces the size of the relocation tables
      used by relocatable kernels.  Since the memory footprint of the static
      kernel image is always much smaller than 4 GB, these relative references
      are assumed to be representable in 32 bits, even when the native word
      size is 64 bits.
      
      On 64-bit architectures, this obviously only works if the distance
      between each relative reference and the chosen anchor point is
      representable in 32 bits, and so the table generation code in
      scripts/kallsyms.c scans the table for the lowest value that is covered
      by the kernel text, and selects it as the anchor point.
      
      However, when using the GOLD linker rather than the default BFD linker
      to build the x86_64 kernel, the symbol phys_offset_64, which is the
      result of arithmetic defined in the linker script, is emitted as a 'T'
      rather than an 'A' type symbol, resulting in scripts/kallsyms.c to
      mistake it for a suitable anchor point, even though it is far away from
      the actual kernel image in the virtual address space.  This results in
      out-of-range warnings from scripts/kallsyms.c and a broken build.
      
      So let's align with the BFD linker, and emit the phys_offset_[32|64]
      symbols as absolute symbols explicitly.  Note that the out of range
      issue does not exist on 32-bit x86, but this patch changes both symbols
      for symmetry.

      Pull cgroup updates from Tejun Heo:
       "cgroup changes for v4.6-rc1.  No userland visible behavior changes in
        this pull request.  I'll send out a separate pull request for the
        addition of cgroup namespace support.
      
         - The biggest change is the revamping of cgroup core task migration
           and controller handling logic.  There are quite a few places where
           controllers and tasks are manipulated.  Previously, many of those
           places implemented custom operations for each specific use case
           assuming specific starting conditions.  While this worked, it makes
           the code fragile and difficult to follow.
      
           The bulk of this pull request restructures these operations so that
           most related operations are performed through common helpers which
           implement recursive (subtrees are always processed consistently)
           and idempotent (they make cgroup hierarchy converge to the target
           state rather than performing operations assuming specific starting
           conditions).  This makes the code a lot easier to understand,
           verify and extend.
      
         - Implicit controller support is added.  This is primarily for using
           perf_event on the v2 hierarchy so that perf can match cgroup v2
           path without requiring the user to do anything special.  The kernel
           portion of perf_event changes is acked but userland changes are
           still pending review.
      
         - cgroup_no_v1= boot parameter added to ease testing cgroup v2 in
           certain environments.
      
         - There is a regression introduced during v4.4 devel cycle where
           attempts to migrate zombie tasks can mess up internal object
           management.  This was fixed earlier this week and included in this
           pull request w/ stable cc'd.
      
         - Misc non-critical fixes and improvements"

      bonding: fix bond_get_stats() · fe30937b
      Eric Dumazet authored
      bond_get_stats() can be called from rtnetlink (with RTNL held)
      or from /proc/net/dev seq handler (with RCU held)
      
      The logic added in commit 5f0c5f73 ("bonding: make global bonding
      stats more reliable") kind of assumed only one cpu could run there.
      
      If multiple threads are reading /proc/net/dev, stats can be really
      messed up after a while.
      
      A second problem is that some fields are 32bit, so we need to properly
      handle the wrap around problem.
      
      Given that RTNL is not always held, we need to use
      bond_for_each_slave_rcu().

      Eli Cohen authored
      Commit 85743f1e ("net/mlx4_core: Set UAR page size to 4KB regardless
      of system page size") introduced dependency where old VF drivers without
      this fix fail to load if the PF driver runs with this commit.
      
      To resolve this add a module parameter which disables that functionality
      by default.  If both the PF and VFs are running with a driver with that
      commit the administrator may set the module param to true.
      
      The module parameter is called enable_4k_uar.

      RDS: TCP: Add sysctl tunables for sndbuf/rcvbuf on rds-tcp socket · c6a58ffe
      Sowmini Varadhan authored
      Add per-net sysctl tunables to set the size of sndbuf and
      rcvbuf on the kernel tcp socket.
      
      The tunables are added at /proc/sys/net/rds/tcp/rds_tcp_sndbuf
      and /proc/sys/net/rds/tcp/rds_tcp_rcvbuf.
      
      These values must be set before accept() or connect(),
      and there may be an arbitrary number of existing rds-tcp
      sockets when the tunable is modified. To make sure that all
      connections in the netns pick up the same value for the tunable,
      we reset existing rds-tcp connections in the netns, so that
      they can reconnect with the new parameters.

      Convert the dma transfers to be dmaengine based, now pxa has a dmaengine
      slave driver. This makes this driver a bit more PXA agnostic.
      
      The driver was only compile tested. The risk is quite small as no
      current PXA platform I'm aware of is using smc911x driver.

           since 2013, and we were initially scheduled to remove it in 3.15.
      
         - Various updates and fixes for NVMe, with the most important being:
      
              - Removal of the per-device NVMe thread, replacing that with a
                watchdog timer instead. From Christoph.
