ARM: make kernel oops easier to read

We don't need the offset for the first function name in each backtrace
entry; this needlessly consumes screen space.  This is virtually always
the first or second instruction in the called function.

Also, recognise stmfd instructions which include r10 as a valid stack
saving instruction, and when dumping the registers, dump six registers
per line rather than five, and fix the wrapping.

kthread_work: wake up worker only when the worker is idle

If the worker is already executing a work item when another is queued,
we can safely skip wakeup without worrying about stalling queue thus
avoiding waking up the busy worker spuriously.  Spurious wakeups
should be fine but still isn't nice and avoiding it is trivial here.

msm: thermal: fix init with msm_thermal

 * not using ioctl interface for this in-kernel solution
so prevent msm_thermal-dev to be built
 * use higher frequency points than my N5 driver because
Bacon rarely gets really hot so we don't need to throttle
as heavy
 * re-structure init->register<->exit flow compared to the
N5 code. We don't rely on board init call anymore. Besides
externs are fugly. The rest is on the msm_thermal merge side

msm: thermal: add my cleaned up in-kernel driver

 * mostly copy-pasta from the N5
 * thermal-engine daemon is disabled in userspace
 * users can now ajudst the thermal throttle point in sysfs
 * well... it's clean :)
 * stability test responds very well and the device doesn't
heat up too much. On stock thermal solution the device rapidly
reached un-bearable temperature on the back (running stability test)
due to it's weird throttling mechanics (at least from what we can
observe since the code is proprietary) and doesn't cool down easily.
With this solution that doesn't happen.
