Subject[RFC PATCH 0/2] ARM: !MMU v7 Cortex-M preemption support

[ cc'ing those who added long back !MMU support & Cortex-M support as
well, though some not working anymore on these ]

An attempt to add preemption support to the !MMU, ARM Cortex-M platform.
With these changes, there is some effect, but not enough to make it

Though as of now i don't have much clue on what the issue could be, it
is being debugged. Meanwhile sending the series as RFC, to get feedback
on what could be missing or whether there is anything inherent in !MMU
and/or Cortex-M platforms that could prevent supporting preemption, etc.

Details on the problems, the way it was tested etc. are mentioned in
2/2. 1/2 is just a change made so as to have a clear diff for easy
review of the preemption support changes.
