Subject: [PATCH] arch: powerpc: kvm: add signed type cast for comparation
Date: Mon, 22 Jul 2013 14:32:35 +0800 [thread overview]
Message-ID: <51ECD203.9050507@asianux.com> (raw)
'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.
