Subject: perf_counter: PERF_TYPE_HW_CACHE is a hardware counter too
X-Git-Tag: v3.12-rc1~14347^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f1a3c979059b2033d0b1cc4f9ee5c90bf92b5f94;p=kernel%2Fkernel-generic.git

perf_counter: PERF_TYPE_HW_CACHE is a hardware counter too

is_software_counter() was missing the new HW_CACHE category.

( This could have caused some counter scheduling artifacts
  with mixed sw and hw counters and counter groups. )
