[Qemu-ppc] [PATCH v4 5/5] ppc: drop vcpu_idt_id bits from the target cod


From: Greg Kurz
Subject: [Qemu-ppc] [PATCH v4 5/5] ppc: drop vcpu_idt_id bits from the target code
Date: Tue, 12 Jul 2016 14:15:02 +0200
User-agent: StGit/0.17.1-dirty

Now that all machine types provide vcpu_dt_id, we can safely drop these
bits from the target code.
