      KVM: Let KVM_SET_SIGNAL_MASK work as advertised · 20b7035c
      Jan H. Schönherr authored
      KVM API says for the signal mask you set via KVM_SET_SIGNAL_MASK, that
      "any unblocked signal received [...] will cause KVM_RUN to return with
      -EINTR" and that "the signal will only be delivered if not blocked by
      the original signal mask".
      This, however, is only true, when the calling task has a signal handler
      registered for a signal. If not, signal evaluation is short-circuited for
      SIG_IGN and SIG_DFL, and the signal is either ignored without KVM_RUN
      returning or the whole process is terminated.
      Make KVM_SET_SIGNAL_MASK behave as advertised by utilizing logic similar
      to that in do_sigtimedwait() to avoid short-circuiting of signals.
