From: Kan Liang kan.liang@linux.intel.com Date: Fri, 2 Mar 2018 07:22:30 -0800 Subject: perf/x86/intel/uncore: Fix Skylake UPI event format

From: Kan Liang kan.liang@linux.intel.com

commit 317660940fd9dddd3201c2f92e25c27902c753fa upstream.

There is no event extension (bit 21) for SKX UPI, so use 'event' instead of 'event_ext'.
