Completely separate the signal delivery path from the notify handler as they have different semantics versus the event handling. The signal delivery only needs to ensure that the interrupted user context was not in a critical section or the section is aborted before it switches to the signal frame context. The signal frame context does not have the original instruction pointer anymore, so that can't be handled on exit to user space. No point in updating the CPU/CID ids as they might change again before the task returns to user space for real. The fast path optimization, which checks for the 'entry from user via interrupt' condition is only available for architectures which use the generic entry code.
