Re: [Qemu-devel] [PATCH] [v2] arm gic saving/loading fix

["Andreas Färber" <afaerber@suse.de>]

Dmitry,

It would be nice to cc the people that have cared to review previous
versions of the patch, Peter Maydell and me. Gets you quicker replies.

Functional ARM patches are being reviewed by our ARM gurus and not by
Stefan Hajnoczi, so please drop qemu-trivial from the cc list, as
pointed out before.

bump for registration. Being no expert for the old savevm format,
