This patch doesn't apply to qemu.git/master because it's based on your
v2 patch.
Please send a single v4 patch that combines v2 and v3 changes and can be
applied to qemu.git/master.
You can use "git rebase -i origin/master" to combine changes and put
them onto the latest origin/master. See the "fixup" and "squash"
commands in git-rebase(1)'s interactive mode for combining patches.
Thanks!
