The exception_action() function in user-exec.c is just a call to cpu_loop_exit() for every target CPU except i386. Since this function is only called if the target's handle_mmu_fault() hook has indicated an MMU fault, and that hook is only called from the handle_cpu_signal() code path, we can simply move the x86-specific setup into that hook, which allows us to remove the TARGET_I386 ifdef from user-exec.c. Of the actions that were done by the call to raise_interrupt_err(): * cpu_svm_check_intercept_param() is a no-op in user mode * check_exception() is a no-op since double faults are impossible for user-mode * assignments to cs->exception_index and env->error_code are no-ops * assigning to env->exception_next_eip is unnecessary because it is not used unless env->exception_is_int is true * cpu_loop_exit_restore() is equivalent to cpu_loop_exit() since pc is 0 which leaves just setting env_>exception_is_int as the action that needs to be added to x86_cpu_handle_mmu_fault().
