cpufreq: interactive: sync android-3.0 with android-3.4
jbd2: quiet "may be used uninitialized in this function" warnings

Building with -Werror on, simple fix
arm: p4notepq-3g_00_defconfig: enable remaining CPU Governors
PM: don't reboot on suspend failure

WARN() instead of BUG(). Want to see if I can catch the serial(?)
port while it's wedged up and try to recover it.
