I think the changelog should explain what the patch does.

With this patch we pass "siginfo_t *info" instead of "int signr" to
do_coredump() and put it into coredump_params, this "info" will be used
by the next patch. Other changes are simple s/signr/info->si_signo/.

Well, this conflicts with another fix which we discussed privately,
perhaps it would be better to push that simple change first...
But OK, this conflict is trivial.
