[Qemu-devel] [PATCH v3 5/7] numa: move numa_node from CPUState into targ


From: Igor Mammedov
Subject: [Qemu-devel] [PATCH v3 5/7] numa: move numa_node from CPUState into target specific classes
Date: Tue, 30 May 2017 18:24:00 +0200

Move vcpu's assocciated numa_node field out of generic CPUState
into inherited classes that actually care about cpu<->numa mapping,
i.e: ARMCPU, PowerPCCPU, X86CPU.
