sigaction.2, signal.7: Document kernel bugs in delivery of signals from CPU exceptions
...
signal.7: Which signal is delivered in response to a CPU exception
is under-documented and does not always make sense. See
<https://bugzilla.kernel.org/show_bug.cgi?id=205831 > for an
example where it doesn’t make sense; per the discussion there,
this cannot be changed because of backward compatibility concerns,
so let’s instead document the problem.
sigaction.2: For related reasons, the kernel doesn’t always fill
in all of the fields of the siginfo_t when delivering signals from
CPU exceptions. Document this as well. I imagine this one
_could_ be fixed, but the problem would still be relevant to
anyone using an older kernel.
