Droping the following patches from series since they are already accepted
- Add support for additional SVM NFP error codes - Add kvm_fast_pio_in support
Changes since v2: - add TwoMemOps flag to detect a opcode with two memory operand. - remove emulator_is_string_op() and add emulator_can_use_gpa(). emulator_can_use_gpa() returns true if its safe to use HW provided GPA.
Changes since v1: - move String op identifier check into new emulator_is_string_op(). - move gpa_available check in emulator_read_write_onepage(). - remove redundant gpa_avail check
