Following tracing fixes:
- Add workqueue forward declaration (for new work, but a nice clean up) - seftest fixes for the new histogram code - Print output fix for hwlat tracer - Fix missing system call events - due to change in x86 syscall naming - Fix kprobe address being used by perf being hashed -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCWuIMShQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qkrdAQDRrgIGcm4pRGrvPiGhp4FeQKUx3woM LY10qMYo3St7zwEAn5oor/e/7KQaQSdKQ7QkL690QU2bTO6FXz4VwE1OcgM= =OHJk -----END PGP SIGNATURE----- Merge tag 'trace-v4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: - Add workqueue forward declaration (for new work, but a nice clean up) - seftest fixes for the new histogram code - Print output fix for hwlat tracer - Fix missing system call events - due to change in x86 syscall naming - Fix kprobe address being used by perf being hashed * tag 'trace-v4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix missing tab for hwlat_detector print format selftests: ftrace: Add a testcase for multiple actions on trigger selftests: ftrace: Fix trigger extended error testcase kprobes: Fix random address output of blacklist file tracing: Fix kernel crash while using empty filter with perf tracing/x86: Update syscall trace events to handle new prefixed syscall func names tracing: Add missing forward declaration
