Subject: [RFC PATCH v2 10/10] KVM: PPC: Ultravisor: Check for MSR_S during hv_reset_msr
Date: Sat, 18 May 2019 11:25:24 -0300	[thread overview]
Message-ID: <20190518142524.28528-11-cclaudio@linux.ibm.com> (raw)
In-Reply-To: <20190518142524.28528-1-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>
