From 1287cb3fa85cd4a0d18402f6a23e1d4c6a9d7b8b Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 4 Jul 2014 12:52:51 +0200 Subject: [PATCH] KVM: PPC: Book3S: Move vcore definition to end of kvm_arch struct When building KVM with a lot of vcores (NR_CPUS is big), we can potentially get out of the ld immediate range for dereferences inside that struct. Move the array to the end of our kvm_arch struct. This fixes compilation issues with NR_CPUS=2048 for me.
