Subject: [PATCH 04/10] target/ppc: 7xx: Machine Check exception cleanup
Date: Thu,  3 Feb 2022 19:42:40 -0300	[thread overview]
Message-ID: <20220203224246.1446652-5-farosas@linux.ibm.com> (raw)
In-Reply-To: <20220203224246.1446652-1-farosas@linux.ibm.com>

There's no MSR_HV in the 7xx.

Also remove 40x and BookE code.
