From 5d226ae56f4dee608099daa599d9df0d12e3b006 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Mon, 22 Jul 2013 14:32:35 +0800 Subject: [PATCH] arch: powerpc: kvm: add signed type cast for comparation 'rmls' is 'unsigned long', lpcr_rmls() will return negative number when failure occurs, so it need a type cast for comparing. 'lpid' is 'unsigned long', kvmppc_alloc_lpid() return negative number when failure occurs, so it need a type cast for comparing.
