Christian asked [1] for EXPORT_SYMBOL_FOR_MODULES() without the _GPL_
part to avoid controversy converting selected existing EXPORT_SYMBOL().
Christoph argued [2] that the _FOR_MODULES() export is intended for
in-tree modules and thus GPL is implied anyway and can be simply dropped
from the export macro name. Peter agreed [3] about the intention for
in-tree modules only, although nothing currently enforces it.
It seems straightforward to add this enforcement, so patch 1 does that.
Patch 2 then drops the _GPL_ from the name and so we're left with
EXPORT_SYMBOL_FOR_MODULES() restricted to in-tree modules only.
Current -next has some new instances of EXPORT_SYMBOL_GPL_FOR_MODULES()
in drivers/tty/serial/8250/8250_rsa.c by commit b20d6576cdb3 ("serial:
8250: export RSA functions"). Hopefully it's resolvable by a merge
commit fixup and we don't need to provide a temporary alias.
