target-arm: kvm - support for single step

Enterprise / Virtualization / QEMU - Alex Bennée [linaro.org] - 17 December 2015 07:37 UTC

This adds support for single-step. There isn't much to do on the QEMU side as after we set-up the request for single step via the debug ioctl it is all handled within the kernel.

The actual setting of the KVM_GUESTDBG_SINGLESTEP flag is already in the common code. If the kernel doesn't support guest debug the ioctl will simply error.
