        needed conflict resolutions this is 3.18-rc1/merge-window material.
      
        These patches have been languishing in my tree for a long while.  The
        fact that I do not have the time to do proper/prompt maintenance of
        this tree is a primary factor in the decision to step down as
        dmaengine maintainer.  That and the fact that the bulk of drivers/dma/
        activity is going through Vinod these days.
      
        The net_dma removal has not been in -next.  It has developed simple
        conflicts against mainline and net-next (for-3.18).
      
        Continuing thanks to Vinod for staying on top of drivers/dma/.

      ipmi: Clear drvdata when interface is removed · 567eded9
      Takao Indoh authored
      This patch fixes a bug on hotmod removing.
      
      After ipmi interface is removed using hotmod, kernel panic occurs when
      rmmod impi_si.  For example, try this:
      
       # echo "remove,"`cat /proc/ipmi/0/params` > \
       /sys/module/ipmi_si/parameters/hotmod
       # rmmod ipmi_si
      
      Then, rmmod fails with the following messages.
      
        ------------[ cut here ]------------

      list_del in cleanup_one_si() fails because the smi_info is already
      removed when hotmod removing.
      
      When ipmi interface is removed by hotmod, smi_info is removed by
      cleanup_one_si(), but is is still set in drvdata.  Therefore when rmmod
      ipmi_si, ipmi_pnp_remove tries to remove it again and fails.
      
      By this patch, a pointer to smi_info in drvdata is cleared when hotmod
      removing so that it will be not accessed when rmmod.

      v2:
      - Clear drvdata in cleanup_one_si
      - Change subject

      ipmi: work around gcc-4.9 build warning · cc4cbe90
      Arnd Bergmann authored
      
      
      Building ipmi on arm with gcc-4.9 results in this warning for an
      allmodconfig build:
      
        drivers/char/ipmi/ipmi_si_intf.c: In function 'ipmi_thread':
        include/linux/time.h:28:5: warning: 'busy_until.tv_sec' may be used uninitialized in this function [-Wmaybe-uninitialized]
          if (lhs->tv_sec > rhs->tv_sec)
             ^
        drivers/char/ipmi/ipmi_si_intf.c:1007:18: note: 'busy_until.tv_sec' was declared here
          struct timespec busy_until;
                          ^
      
      The warning is bogus and this case can not occur.  Apparently this is a
      false positive resulting from gcc getting a little smarter about
      tracking assignments but not smart enough.
      
      Marking the ipmi_thread_busy_wait function as inline gives the gcc
      optimization logic enough information to figure out for itself that the
      case cannot happen, which gets rid of the warning without adding any
      fake initialization.

      If an IPMI controller is used by the firmware and as such marked with
      a reserved status, we shouldn't use it.

      ipmi: Clean up the error handling for channel config errors · 1f668423
      Corey Minyard authored
      
      
      The code to send the channel config errors was missing an error report
      in one place and needed some more information in another, and had an
      extraneous bit of code.  Clean all that up.
