[PATCH 06/11] target/ppc: booke: Instruction storage exception cleanup


From: Fabiano Rosas
Subject: [PATCH 06/11] target/ppc: booke: Instruction storage exception cleanup
Date: Fri, 28 Jan 2022 19:40:13 -0300

The SRR1 should be set to the MSR value. There are no diagnostic bits
in the SRR1 for BookE.

Note that this fixes a bug where MSR_GS would be set and Linux would
go into KVM code when there's no KVM guest.
