syscall return values should be cleared. The system calls getcontext() and swapcontext() want to return 0 on success but these contexts can be switched to at a later time so the return values need to be cleared in the saved register sets. Other callers of get_mcontext() would normally want the context without clearing the return values. Remove the i386-specific context saving from the KSE code. get_mcontext() is not i386-specific any more. Fix a bad pointer in the alpha get_mcontext() code. The context was being bcopy()'d from &td->tf_frame, but tf_frame is itself a pointer, so the thread was being copied instead. Spotted by jake. Glanced at by: jake Reviewed by: bde (months ago) |
