      Pull ktest confusion fix from Steven Rostedt:
       "With the v3.7-rc2 kernel, the network cards on my target boxes were
        not being brought up.
      
        I found that the modules for the network was not being installed.
        This was due to the config CONFIG_MODULES_USE_ELF_RELA that came
        before CONFIG_MODULES, and confused ktest in thinking that
        CONFIG_MODULES=y was not found.
      
        Ktest needs to test all configs and not just stop if something starts
        with CONFIG_MODULES."

       "Bug fixes for a number of ARM platforms, mostly OMAP, imx and at91.
      
        These come a little later than I had hoped but unfortunately we had a

        how to deal with those in the meantime."

      Lock splice_read and splice_write functions · 1a25b1c4
      Mikulas Patocka authored
      Functions generic_file_splice_read and generic_file_splice_write access
      the pagecache directly. For block devices these functions must be locked
      so that block size is not changed while they are in progress.
      
      This patch is an additional fix for commit b87570f5 ("Fix a crash
      when block device is read and block size is changed at the same time")
      that locked aio_read, aio_write and mmap against block size change.

      percpu-rw-semaphores: use rcu_read_lock_sched · 1bf11c53
      Mikulas Patocka authored
      Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched
      instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu.
      
      This is an optimization. The RCU-protected region is very small, so
      there will be no latency problems if we disable preempt in this region.
      
      So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates
      to preempt_disable / preempt_disable. It is smaller (and supposedly
      faster) than preemptible rcu_read_lock / rcu_read_unlock.

      percpu-rw-semaphores: use light/heavy barriers · 5c1eabe6
      Mikulas Patocka authored
      This patch introduces new barrier pair light_mb() and heavy_mb() for
      percpu rw semaphores.
      
      This patch fixes a bug in percpu-rw-semaphores where a barrier was
      missing in percpu_up_write.
      
      This patch improves performance on the read path of
      percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in
      percpu_up_read. This patch changes it to a compiler barrier and removes
      the "#if defined(X86) ..." condition.
