[Qemu-devel] [PATCH] icount: remove useless exit_request assignment

[Pavel Dovgalyuk]

This patch removes unneeded assignment to cpu->exit_request.
cpu_exec_nocache executes all available instructions and therefore
icount becomes 0. Then other conditions will break the execution
loop, making assignment to cpu->exit_request useless.

This patch should be applied over Paolo's series:
