Wire up the clone3() syscall for m68k. The special entry point is done in
assembler as was done for clone() as well. This is needed because all
registers need to be saved. The C wrapper then calls the generic
sys_clone3() with the correct arguments.
Tested on A1200 using the simple test program from:
https://lore.kernel.org/lkml/20190716130631.tohj4ub54md25dys@xxxxxxxxxx/
Please note that we now have a growing test-suite for the clone3()
syscall under
tools/testing/selftests/clone3/*
You can test on a suitable kernel with
make TARGETS=clone3 kselftest

Thanks a lot!
Works fine on ARAnyM, too.
Looks good to me, but I'll wait a bit before applying, so the syscall experts
can chime in, if needed.
Otherwise this looks good to me.
Thanks for moving this forward. One day we'll be able to remove
ARCH_WANT_SYS_CLONE3 completely. :)
