From b835e919f022d768abdf00e8dc94f1a23fdcab15 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Mon, 17 Jan 2011 19:29:34 +0100 Subject: [PATCH] target-mips: fix save_cpu_state() calls The rule is: - don't save PC if the exception is only triggered by softmmu. - save PC if the exception can be triggered by an helper. Fix a 64-bit kernel crash when loading modules.
