Flo: Implement kexec-hardboot

"Allows hard booting (i.e., with a full hardware reboot) to a kernel
previously loaded in memory by kexec.  This works around the problem of
soft-booted kernel hangs due to improper device shutdown and/or
reinitialization."
More info in /arch/arm/Kconfig.

Original author: Mike Kasick <mike@kasick.org>

Vojtech Bocek <vbocek@gmail.com>:
  I've ported it to flo, it is based of my grouper port, which is based of
  Asus TF201 patches ported by Jens Andersen <jens.andersen@gmail.com>.

  I've moved atags copying from guest to the host kernel, which means there
  is no need to patch the guest kernel, assuming the --mem-min in kexec call
  is within the first 256MB of System RAM, otherwise it will take a long time
  to load. I've also fixed /proc/atags entry, which would give the kexec-tools
  userspace binary only the first 1024 bytes of atags,
  see arch/arm/kernel/atags.c for more details.

  Other than that, memory-reservation code for the hardboot page and
  some assembler to do the watchdog reset on MSM chip are new for this device.

intelli_plug: use rq_stats to help detect artificial or constant loads

benchmarks often create fake / artificial loads at a constant rate.  These
type of loads are not detected corectly by run average algorithms. Use
the run queue stats to help detect these cases and bring up the cores in
correspondence.

intelli_plug: add dynamic load sampling rate logic

Add dynamic sampling logic based on load. If load is high and required more
than 2 cores, increase the sampling rate for a duration of 3 seconds to help
manage the load better during this time.  Once duration expires, revert back
to lazier sampling rate for better batter performance.

ARGH... really angry at CAF code.

some cpufreq driver APIs are incredibly unstable with some of the older

tons of variations out there, so rather than depending on a fix, make
intelli_plug more universal by avoiding the troubling APIs altogether
