KVM: x86 emulator: Allow accessing IDT via emulator ops
The patch adds a new member get_idt() to x86_emulate_ops. It also adds a function to get the idt in order to be used by the emulator. This is needed for real mode interrupt injection and the emulation of int instructions. Signed-off-by: Mohammed Gamal <m.gamal005@gmail.com> Signed-off-by: Avi Kivity <avi@redhat.com>
