    AMD64 - Fix bogus signal interruption
    
    * The TF_XFLAGS field in the trap frame was not getting cleared on trap and
      syscall entry.  This field can cause a mailbox signal to be flagged in
      the signal frame which in turn can cause the next blockable system call
      to return EINTR.
    
      This fixes the last issue with mount_mfs.
    
    * Cast the signal function to intptr_t rather then int.
