[Qemu-devel] [PATCH] do_interrupt64 shouldn't be called when GIF is not set.

[Himanshu Chauhan]

I am not very sure about the place(s) we would need this. But I think
this is required. Please advise.

When having SVM enabled, the do_interrupt64 shouldn't be
called unless GIF is set otherwise this causes random behaviour
especially bad TR in case guest is running.
