Hi, The series includes various independent fixes in x86 emulator. The first patch fix #UD intercept handlers (both in VMX and SVM) to actually exit to user-mode when required by the x86 emulator. The second patch fixes a bug in the return-value of handle_emulation_failure() which cause callers to not exit user-mode even though the x86 emulator intended to do so. The third patch fixes bad emulation_type passed to the x86 emulator from a wrapper utility function (emulate_instruction()). Thanks. -Liran Alon
