This patch fixes emulate_syscall(), emulate_sysenter() and emulate_sysexit() to handle injected faults properly. Even though original code injects faults in these functions, we cannot handle these unless we use the different return value from the UNHANDLEABLE case. So this patch use X86EMUL_* codes instead of -1 and 0 and makes x86_emulate_insn() to handle these propagated faults. Be sure that, in x86_emulate_insn(), goto cannot_emulate and goto done with rc equals X86EMUL_UNHANDLEABLE have same effect.
