From 322740efbb7ca26df845161e61cc41484b7e328e Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Mon, 25 Jan 2016 23:33:30 +0100 Subject: Revert "um: Fix get_signal() usage" Commit db2f24dc240856fb1d78005307f1523b7b3c121b was plain wrong. I did not realize the we are allowed to loop here. In fact we have to loop and must not return to userspace before all SIGSEGVs have been delivered. Other archs do this directly in their entry code, UML does it here.
