       "The main update this time around is the addition of a standard DT
        binding for specifying the endianness of devices.  This allows drivers
        to support any endianness of device register map without any code,
        useful for configurable IP blocks.
        There's also a few bug fixes that I didn't get round to sending, none
        of them terribly severe or new, and a reduction in size for struct

      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` > \
       # rmmod ipmi_si
      Then, rmmod fails with the following messages.
        ------------[ cut here ]------------
        WARNING: CPU: 12 PID: 10819 at /mnt/repos/linux/lib/list_debug.c:53 __list_del_entry+0x63/0xd0()

        Hardware name: FUJITSU-SV PRIMERGY BX920 S2/D3030, BIOS 080015 Rev.3D81.3030 02/10/2012
        Call Trace:
          cleanup_one_si+0x2a/0x230 [ipmi_si]
          ipmi_pnp_remove+0x15/0x20 [ipmi_si]
          cleanup_ipmi_si+0xbc/0xf0 [ipmi_si]
        ---[ end trace 70b4377268f85c23 ]---
      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.
      - 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.
