[PATCH v2 02/10] KVM: PPC: mov nip/ctr/lr/xer registers to pt_regs in kvm_vcpu_arch
wei.guo.simon at gmail.com
wei.guo.simon at gmail.com
Mon May 7 16:20:08 AEST 2018
From: Simon Guo <wei.guo.simon at gmail.com>
This patch moves nip/ctr/lr/xer registers from scattered places in
kvm_vcpu_arch to pt_regs structure.
cr register is "unsigned long" in pt_regs and u32 in vcpu->arch.
It will need more consideration and may move in later patches.
