Subject: perfcounters: include asm/perf_counter.h only if CONFIG_PERF_COUNTERS=y
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=e44aef58ecfbe061eb4c53b939bcc35fb1bee82d;p=deliverable%2Flinux.git

perfcounters: include asm/perf_counter.h only if CONFIG_PERF_COUNTERS=y

Impact: build fix on ia64

KOSAKI Motohiro reported that -tip doesnt build on ia64 because
asm/perf_counter.h only exists on x86 for now. Fix it.
