Subject: [PATCH 7/8] target/ppc: 405: External exception cleanup
Date: Mon, 10 Jan 2022 15:15:45 -0300 [thread overview]
Message-ID: <20220110181546.4131853-8-farosas@linux.ibm.com> (raw)
In-Reply-To: <20220110181546.4131853-1-farosas@linux.ibm.com>
405 has no MSR_HV and EPR is BookE only so we can remove it all.
