Subject: [PATCH kernel v10 07/10] KVM: PPC: Pass kvm* to kvmppc_find_table()
Date: Fri, 17 Mar 2017 16:09:56 +1100	[thread overview]
Message-ID: <20170317050959.37312-8-aik@ozlabs.ru> (raw)
In-Reply-To: <20170317050959.37312-1-aik@ozlabs.ru>

The guest view TCE tables are per KVM anyway (not per VCPU) so pass kvm*
there. This will be used in the following patches where we will be
attaching VFIO containers to LIOBNs via ioctl() to KVM (rather than
to VCPU).
