Subject: perfcounters, x86: fix sw counters on non-PMC CPUs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=088e2852c858159d47f71ee8da38e0fb1b21f806;p=mv-sheeva.git

perfcounters, x86: fix sw counters on non-PMC CPUs

Make perf_max_counters default to at least 1 - this allows the sw
counters to be used.
