Subject: Re: Fwd: [PATCH] KVM: x86: remove unneeded variable

+Dave, -Ave

scripts/get_maintainers.pl is your friend.  It avoids typos (well, if you wrap
it with scripts instead of copy+pasting), and makes sures patches get routed to
the right folks (KVM x86 patches are routed through the KVM tree, not the tip tree).

Please resend, unless mine eyes deceive, this is whitespace damaged.
