From 8d17dd041a548b016ff401d36be6b2563c940ed5 Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 23 May 2013 09:49:08 -0700 Subject: [PATCH] mips/kvm: Use ARRAY_SIZE() instead of hardcoded constants in kvm_arch_vcpu_ioctl_{s,g}et_regs Also we cannot set special zero register, so force it to zero.
