[Qemu-devel] [RFC PATCH V7 18/19] mttcg: signal the associated cpu anyway.

[fred . konrad]

From: KONRAD Frederic <address@hidden>

We might have a race here. If current_cpu is about to be set then cpu_exit won't
be called and we don't exit TCG. This was probably an issue with old
implementation as well.
