        contains:
      
         - Removal of dead code from Gu Zheng.
      
         - Revert of two bad fixes that went in earlier in this round, marking
           things as __init that were not purely used from init.
      
         - A fix for blk_mq_start_hw_queue() using the __blk_mq_run_hw_queue(),
           which could place us wrongly.  Make it use the non __ variant,
           which handles cases where we are called from the wrong CPU set.
           From me.
      
         - A fix for drbd, which allocates discard requests without room for
           the SCSI payload.  From Lars Ellenberg.
      
         - A fix for user-after-free in the blkcg code from Tejun.
      
         - Addition of limiting gaps in SG lists, if the hardware needs it.
           This is the last pre-req patch for blk-mq to enable the full NVMe
           conversion.  Could wait until 3.17, but it's simple enough so would
           be nice to have everything we need for the NVMe port in the 3.17

      Fix 32-bit regression in block device read(2) · 0b86dbf6
      Al Viro authored
      blkdev_read_iter() wants to cap the iov_iter by the amount of data
      remaining to the end of device.  That's what iov_iter_truncate() is for
      (trim iter->count if it's above the given limit).  So far, so good, but
      the argument of iov_iter_truncate() is size_t, so on 32bit boxen (in
      case of a large device) we end up with that upper limit truncated down
      to 32 bits *before* comparing it with iter->count.
      
      Easily fixed by making iov_iter_truncate() take 64bit argument - it does
      the right thing after such change (we only reach the assignment in there
      when the current value of iter->count is greater than the limit, i.e.
      for anything that would get truncated we don't reach the assignment at
      all) and that argument is not the new value of iter->count - it's an
      upper limit for such.
      
      The overhead of passing u64 is not an issue - the thing is inlined, so
      callers passing size_t won't pay any penalty.

      mfd: ab8500: Fix dt irq mapping · 7602e05d
      Grygorii Strashko authored
      The AD8500 defines itself as interrupt-controller in DT,
      but it doesn't assign DT node to IRQ domain when creates it.
      As result, of_irq_xx() helpers don't work because they can't
      find necessary IRQ domain.
      
      Hence, fix it by assigning AD8500 core device DT node to IRQ
      domain when it's created.
      
      This patch fixes STE u8500 Snowball boot failure reported by Kevin Hilman

      Arnd Bergmann authored
      This driver depends on I2C, which may be a loadable module.
      While you'd probably want both to be built-in in practice,
      allowing a modular build avoids possible randconfig link
      errors.

      mfd: UCB1x00: Enable modular build · 1c93c725
      Arnd Bergmann authored
      The UCB1200 / UCB1300 driver uses the MCP_SA11X0 driver, which
      can be a loadable module, but this results in a link error
      when UCB1200 itself is built-in:
      
      drivers/built-in.o: In function `ucb1x00_io_set_dir':
      :(.text+0x4a364): undefined reference to `mcp_reg_write'
      drivers/built-in.o: In function `ucb1x00_io_write':
      :(.text+0x4a3dc): undefined reference to `mcp_reg_write'
      drivers/built-in.o: In function `ucb1x00_io_read':
      :(.text+0x4a400): undefined reference to `mcp_reg_read'
      drivers/built-in.o: In function `ucb1x00_adc_enable':
      :(.text+0x4a460): undefined reference to `mcp_enable'
      ...
      
      This can easily be resolved by making CONFIG_MCP_UCB1200 itself
      a tristate option, since that causes Kconfig to track the
      dependency correctly.

      ipv4: fix dst race in sk_dst_get() · f8864972
      Eric Dumazet authored
      When IP route cache had been removed in linux-3.6, we broke assumption
      that dst entries were all freed after rcu grace period. DST_NOCACHE
      dst were supposed to be freed from dst_release(). But it appears
      we want to keep such dst around, either in UDP sockets or tunnels.
      
      In sk_dst_get() we need to make sure dst refcount is not 0
      before incrementing it, or else we might end up freeing a dst
      twice.
      
      DST_NOCACHE set on a dst does not mean this dst can not be attached
      to a socket or a tunnel.
      
      Then, before actual freeing, we need to observe a rcu grace period
      to make sure all other cpus can catch the fact the dst is no longer
      usable.
