I suspect this goes for other ARM arches as well, does it not?
Please fix globally.

(considering this is the second time in a small period where such a global
fixing is needed, I'll have a look at commonalizing start.S files across
all ARM arches if possible and submit a patch for the coming window -- unless
someone else has this ongoing already)

Amicalement,
