Umm. I don't think that is possible. You need architecture-specific code to even get access to all registers to copy and get a signal-handler-compatible stack frame. See for example arch/alpha/kernel/entry.S with the switch-stack thing etc. I don't think there is any way to make that even remotely architecture-neutral.
