Fast emulation of processor I/O for IN was disabled on x86 (both VMX and SVM) some years ago due to a buggy implementation. The addition of kvm_fast_pio_in(), used by SVM, re-introduced (functional!) fast emulation of IN. Piggyback SVM's work and use kvm_fast_pio_in() on VMX instead of performing full emulation of IN.
