From 6c8c0c4dc0e98ee2191211d66e9f876e95787073 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Mon, 22 Jul 2013 04:40:38 +0100 Subject: [PATCH] arm64: KVM: use 'int' instead of 'u32' for variable 'target' in kvm_host.h. 'target' will be set to '-1' in kvm_arch_vcpu_init(), and it need check 'target' whether less than zero or not in kvm_vcpu_initialized(). So need define target as 'int' instead of 'u32', just like ARM has done.
