Subject: arch: powerpc: kvm: add signed type cast for comparation
X-Git-Tag: v3.12-rc1~143^2~5^2~6

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.
