Ouch... That's quite likely to be impossible to distribute, since the
requirements of v2 and v3 are mutually incompatible and quite a bit of
the kernel is under v2-only, not v2-or-any-later-version.
Seriously, folks - talk to lawyers; if the result is *NOT* a mere aggregation
(i.e. is derived work wrt the kernel proper), you are in a copyright violation.
Moreover, if anything in that file is derived from others' work, you can't
use GPL-3.0 unless the terms for everything it's derived from allow
redistribution under GPL-3.0. Anything derived from others' GPL-2.0 work
(as opposed to GPL-2.0-or-later one) can't be relicensed to GPL-3.0 at
all.
