Subject: [PATCH 11/11] target/ppc: booke: System Reset exception cleanup
Date: Fri, 28 Jan 2022 19:40:18 -0300	[thread overview]
Message-ID: <20220128224018.1228062-12-farosas@linux.ibm.com> (raw)
In-Reply-To: <20220128224018.1228062-1-farosas@linux.ibm.com>

There is no MSR_HV in BookE, so remove all of the HV logic.
