there are some types of accelerators in qemu, and all accelerators
have their own file except tcg. tcg accelerator is also defined in
accel.c file. tcg accelerator file will be splited from accel.c and
re-name to tcg-all.c. accel/ directory will be created to include
kvm and tcg related files.

create one stub subdirectory, which will include accelerator's stub
files.

Queued, thanks (except I'm not sure why you're moving exec.c, so I've
undone that, and tcg-runtime.c probably fits better in tcg/).

Thanks Paolo for your great help!
as for exec.c, i ever thought this file is related with system and moved it to here.
You are right, tcg-runtime.c is BSD Licenced file, which should be moved to tcg/.
Whether can i release V4 for those moving? thanks!

Yang.

If we do that, there would many more files to move (e.g. ioport.c,
memory.c, user-exec.c). I think it's better to leave exec.c in the root
for now.

Don't worry, I can do the moving.
