H A D | kvm.h | 61c7bbd2 Mon May 12 04:51:37 CDT 2014 Alexander Graf <agraf@suse.de> kvm: Fix enable_cap helpers on older gcc Commit 40f1ee27aa1 introduced handy helpers for enable_cap calls on vcpu and vm level. Unfortunately some older gcc versions (4.7.1, 4.6) seem to choke on signedness detection in inline created variables: target-ppc/kvm.c: In function 'kvmppc_booke_watchdog_enable': target-ppc/kvm.c:1302:21: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits] target-ppc/kvm.c: In function 'kvmppc_set_papr': target-ppc/kvm.c:1504:21: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits] However - thanks to Thomas Huth for the suggestion - we can just cast the offending potentially 0 value to a signed type, making the comparison signed.
