Indeed. CONFIG_PERFCTR=n leads to compile-time warnings
from the syscall prototypes in <linux/perfctr.h>.
I'm not sure if providing dummy struct declarations is
cleaner than bracketing the offending code inside #ifdef
CONFIG_PERFCTR, but this patch should fix the warnings for now.

Andrew: please apply.
