From 5310799a8b687a6cf0b5dbabaa3b6ddc8a6a7a1a Mon Sep 17 00:00:00 2001 From: Balbir Singh Date: Thu, 10 Nov 2016 15:37:31 +1100 Subject: [PATCH] FU exceptions should carry a cause (IC) As per the ISA we need a cause and executing a tabort r9 in libc for example causes a EXCP_FU exception, we don't wire up the IC (cause) when we post the exception. The cause is required for the kernel to do the right thing. The fix applies only to 64 bit ppc targets.
