From Cortex-M reference manuals, the nvic supports up to 240 interrupts.
So the number of entries in vectors table is up to 256.
This patch adds a new config flag to specify the number of external interrupts.
Some ifdeferies are added in order to respect the natural alignment without
wasting too much space on smaller systems.

I would have called this CONFIG_CPU_V7M_NUM_IRQ to match the already
existing CPU_V7M symbol.
That's better indeed.
It will be changed in v3.

Who do you target to apply this series?
I guess it should go through Russell's Patch Tracking System?
Sorry, I answered your question too quickly.
I meant this patch should go through Russell's Patch Tracking System.
For the other patches, I think it should be picked by their respective
maintainers.
Or I can create an immutable tag (on github or kernel.org?) that will
be merged by the different sub-systems?
What would you advise?
Thanks,
Maxime
