Subject: [PATCH 2/3] KVM: PPC: Fix vmx/vsx mixup in mmio emulation
Date: Thu, 23 Dec 2021 18:15:27 -0300	[thread overview]
Message-ID: <20211223211528.3560711-3-farosas@linux.ibm.com> (raw)
In-Reply-To: <20211223211528.3560711-1-farosas@linux.ibm.com>

The MMIO emulation code for vector instructions is duplicated between
VSX and VMX. When emulating VMX we should check the VMX copy size
instead of the VSX one.

Fixes: acc9eb9305fe ("KVM: PPC: Reimplement LOAD_VMX/STORE_VMX instruction ...")
