[PATCH 45/45] KVM: ppc: create struct kvm_vcpu_44x and introduce container_of() accessor

Avi Kivity
2008-12-08T11:42:58Z

From: Hollis Blanchard <hollisb@us.ibm.com>

This patch doesn't yet move all 44x-specific data into the new structure, but
is the first step down that path. In the future we may also want to create a
struct kvm_vcpu_booke.

Based on patch from Liu Yu <yu.liu@freescale.com>.
