      Pull ARM updates from Russell King:
       "Included in these updates are:
         - Performance optimisation to avoid writing the control register at
           every exception.
         - Use static inline instead of extern inline in ftrace code.
         - Crypto ARM assembly updates for big endian
         - Alignment of initrd/.init memory to page sizes when freeing to
           ensure that we fully free the regions
         - Add gcov support
         - A couple of preparatory patches for VDSO support: use
           _install_special_mapping, and randomize the sigpage placement above
           stack.
         - Add L2 ePAPR DT cache properties so that DT can specify the cache
           geometry.
         - Preparatory patch for FIQ (NMI) kernel C code for things like
           spinlock lockup debug.  Following on from this are a couple of my
           patches cleaning up show_regs() and removing an unused (probably
           since 1.x days) do_unexp_fiq() function.
         - Use pr_warn() rather than pr_warning().
         - A number of cleanups (smp, footbridge, return_address)"

      Pull KVM updates from Paolo Bonzini:
       "Fixes and features for 3.18.
      
        Apart from the usual cleanups, here is the summary of new features:
      
         - s390 moves closer towards host large page support
      
         - PowerPC has improved support for debugging (both inside the guest
           and via gdbstub) and support for e6500 processors
      
         - ARM/ARM64 support read-only memory (which is necessary to put
           firmware in emulated NOR flash)
      
         - x86 has the usual emulator fixes and nested virtualization
           improvements (including improved Windows support on Intel and
           Jailhouse hypervisor support on AMD), adaptive PLE which helps
           overcommitting of huge guests.  Also included are some patches that
           make KVM more friendly to memory hot-unplug, and fixes for rare
           caching bugs.
      
        Two patches have trivial mm/ parts that were acked by Rik and Andrew.
      
        Note: I will soon switch to a subkey for signing purposes"

      Fix up missing dmaengine header inclusion from qce crypto engine · f89f4a06
      Linus Torvalds authored
      Commit 7bced397
      
       ("net_dma: simple removal") removed the long-dead
      net_dma code, but unintentionally broke the build for the qualcomm
      crypto engine (qce) that had accidentally depended on the inclusion of
      <linux/dmaengine.h> through the networking header files that used to
      have it.
      
      Add the required dmaengine.h include explicitly to fix the breakage.

      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.

      - 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.
