Subject: [PATCH v3 9/9] KVM: PPC: Ultravisor: Check for MSR_S during hv_reset_msr
Date: Thu, 6 Jun 2019 14:36:14 -0300 [thread overview]
Message-ID: <20190606173614.32090-10-cclaudio@linux.ibm.com> (raw)
In-Reply-To: <20190606173614.32090-1-cclaudio@linux.ibm.com>
From: Michael Anderson <andmike@linux.ibm.com>
- Check for MSR_S so that kvmppc_set_msr will include. Prior to this
change return to guest would not have the S bit set.
- Patch based on comment from Paul Mackerras <pmac@au1.ibm.com>
