Subject: [PATCH v4 8/8] KVM: PPC: Ultravisor: Check for MSR_S during hv_reset_msr
Date: Fri, 28 Jun 2019 17:08:25 -0300	[thread overview]
Message-ID: <20190628200825.31049-9-cclaudio@linux.ibm.com> (raw)
In-Reply-To: <20190628200825.31049-1-cclaudio@linux.ibm.com>

From: Michael Anderson <andmike@linux.ibm.com>

 - Check for MSR_S so that kvmppc_set_msr will include it. 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>
