After merging with 2.4.6 kernel, ret_from_sys_call (and o32_ret_from_sys_call) does not check whether it returns to kernel mode or not. syscall may happen in kernel mode, so we should check KU_USER bits (as done in past code). Is this right? At least, currently DO_FAULT() jumps to ret_from_sys_call and it may cause problems. If page fault happened in kernel code when any signals pending, do_signal() is called before returning to kernel and it fails to setup sigcontext. Any ideas? --- Atsushi Nemoto
