The patch summary is correct, but the help text is not.

Exactly how is this not correct? While on PowerPC at the moment the TCG
code is not there (and you need this option anyway)...on x86 using this
option does mean by passing the TCG CPU emulation code. If you use this
option you have to be using KVM.. what text do you think whould be
better ?

Re: [PATCH] Add --disable-cpu-emulation to qemu help screen

[Jerone Young]

Whoops ok looks like I made a mistake with the help text. I use
"--no-cpu-emulation" .. when I meant "--disable-cpu-emulation" that was
in the summary. I think I got my self screwedup by the defines we use in
the code. This is what Hollis was pointing out.

Here is a more proper patch.
