[Xen-devel] [PATCH] xen: arm: mark early_panic as a noreturn function

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Otherwise gcc complains about variables being used when not
initialised when in fact that point is never reached.

There aren't any instances of this in tree right now, I noticed this
while developing another patch.
