Pull perf fixes from Ingo Molnar: "An uncharacteristically large number of bugs popped up in the last week: - various tooling fixes, two crashes and build problems - two Intel PT fixes - an KNL uncore driver fix - an Intel PMU driver fix" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf stat: Fallback to user only counters when perf_event_paranoid > 1 perf evsel: Handle EACCESS + perf_event_paranoid=2 in fallback() perf evsel: Improve EPERM error handling in open_strerror() tools lib traceevent: Do not reassign parg after collapse_tree() perf probe: Check if dwarf_getlocations() is available perf dwarf: Guard !x86_64 definitions under #ifdef else clause perf tools: Use readdir() instead of deprecated readdir_r() perf thread_map: Use readdir() instead of deprecated readdir_r() perf script: Use readdir() instead of deprecated readdir_r() perf tools: Use readdir() instead of deprecated readdir_r() perf/core: Disable the event on a truncated AUX record perf/x86/intel/pt: Generate PMI in the STOP region as well perf/x86: Fix undefined shift on 32-bit kernels perf/x86/msr: Fix SMI overflow perf/x86/intel/uncore: Fix CHA registers configuration procedure for Knights Landing platform perf diff: Fix duplicated output column
