intellithemal v2: an in-kernel thermal monitor for Qualcomm 8974+ SOCs

intellithermal version 2 is based originally from Qualcomm's repo adapted to
operate as a standalone in-kernel thermal throttling worker.  It can read
DTS entries for configuration as well as sysfs tunable knobs for both compile
time and run time configurations.

this kernel worker can completely replace the closed source thermald and
thermal-engine daemons from Qualcomm.

ext4: Speedup WB_SYNC_ALL pass called from sync(2)

When doing filesystem wide sync, there's no need to force transaction
commit (or synchronously write inode buffer) separately for each inode
because ext4_sync_fs() takes care of forcing commit at the end (VFS
takes care of flushing buffer cache, respectively). Most of the time
this slowness doesn't manifest because previous WB_SYNC_NONE writeback
doesn't leave much to write but when there are processes aggressively
creating new files and several filesystems to sync, the sync slowness
can be noticeable. In the following test script sync(1) takes around 6
minutes when there are two ext4 filesystems mounted on a standard SATA
drive. After this patch sync takes a couple of seconds so we have about
two orders of magnitude improvement.

      function run_writers
      {
        for (( i = 0; i < 10; i++ )); do
          mkdir $1/dir$i
          for (( j = 0; j < 40000; j++ )); do
            dd if=/dev/zero of=$1/dir$i/$j bs=4k count=4 &>/dev/null
          done &
        done
      }

      for dir in "$@"; do
        run_writers $dir
      done

      sleep 40
      time sync
