Subject: [PATCH 07/10] target/ppc: 7xx: System Call exception cleanup
Date: Thu,  3 Feb 2022 19:42:43 -0300	[thread overview]
Message-ID: <20220203224246.1446652-8-farosas@linux.ibm.com> (raw)
In-Reply-To: <20220203224246.1446652-1-farosas@linux.ibm.com>

There is no Hypervisor mode in the 7xx, so no hypercalls.
