OK, thank you for your work (originally, I really did not kown that it
would generate so many patches -- almost 3 times that I supposed).

OK, thanks, I shall continue based on it, after it is integrated into
qemu master (after Reviewed-by another members).

During the next 2-4 days I shall try to fix one gcc bugzilla issue, then
turn back to qemu, hope I can succeed. (during these passed days, I sent
3 paches to kernel, and 2 of them are applied, one is waiting review).


Thanks.
