Pull perf fixes from Ingo Molnar: "Mostly tooling fixes, but also two PMU driver fixes" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf tools powerpc: Use dwfl_report_elf() instead of offline. perf tools: Fix segfault for symbol annotation on TUI perf test: Fix dwarf unwind using libunwind. perf tools: Avoid build splat for syscall numbers with uclibc perf tools: Elide strlcpy warning with uclibc perf tools: Fix statfs.f_type data type mismatch build error with uclibc tools: Remove bitops/hweight usage of bits in tools/perf perf machine: Fix __machine__findnew_thread() error path perf tools: Fix building error in x86_64 when dwarf unwind is on perf probe: Propagate error code when write(2) failed perf/x86/intel: Fix bug for "cycles:p" and "cycles:pp" on SLM perf/rapl: Fix sysfs_show() initialization for RAPL PMU

* NetLabel Domain Hash Table
*
* This file manages the domain hash table that NetLabel uses to determine
* which network labeling protocol to use for a given domain. The NetLabel
* system manages static and dynamic label mappings for network protocols such
