File 0096-KVM-PPC-Expose-fixup-hcall-capabili.patch of Package qemu.313
From 6658a1d23b9960a98a0be1c586a93703ea71cbda Mon Sep 17 00:00:00 2001 From: Alexander Graf <agraf@suse.de> Date: Wed, 4 Jun 2014 12:14:08 +0200 Subject: [PATCH] KVM: PPC: Expose fixup hcall capability New kvm versions expose a PPC_FIXUP_HCALL capability. Make it visible to machine code so we can take decisions based on it.
