From a6d5ff04e83b36e0d5c2c50ef4d18e9f38b5abc2 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 5 May 2009 12:49:47 -0700 Subject: [PATCH] MIPS: Use force_sig when handling address errors. When init is started it is SIGNAL_UNKILLABLE. If it were to get an address error, we would try to send it SIGBUS, but it would be ignored and the faulting instruction restarted. This results in an endless loop. We need to use force_sig() instead so it will actually die and give us some useful information.
