Re: [Qemu-devel] [PATCH 0/6 v5] tilegx: Can load elf64 tilegx binary successfully for linux-user

[Chen Gang]

Hello All:

I have to leave Sunrus, the mail address (address@hidden) will
be closed soon (Sunrus will be closed soon because of money, I guess).

I change my new email address (address@hidden) to continue
communicating. address@hidden is still have effect, but it is
not stable (gmail in China is not stable).

And if the patches can pass checking, please add me as the maintainer,
and let Andreas, Chris, Richard, and Peter as Reviewed-by.

Thanks.
