Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull perf tooling updates from Ingo Molnar:
 "Tooling changes only: fixes and a few stray improvements.

  Most of the diffstat is dominated by a PowerPC related fix of system
  call trace output beautification that allows us to (again) use the
  UAPI header version and sync up with the kernel's version of PowerPC
  system call names in the arch/powerpc/kernel/syscalls/syscall.tbl
  header"

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits)
  tools headers powerpc: Remove unistd.h
  perf powerpc: Rework syscall table generation
  perf symbols: Add 'arch_cpu_idle' to the list of kernel idle symbols
  tools include uapi: Sync linux/if_link.h copy with the kernel sources
  tools include uapi: Sync linux/vhost.h with the kernel sources
  tools include uapi: Sync linux/fs.h copy with the kernel sources
  perf beauty: Switch from using uapi/linux/fs.h to uapi/linux/mount.h
  tools include uapi: Grab a copy of linux/mount.h
  perf top: Lift restriction on using callchains without "sym" in --sort
  tools lib traceevent: Remove tep_data_event_from_type() API
  tools lib traceevent: Rename tep_is_file_bigendian() to tep_file_bigendian()
  tools lib traceevent: Changed return logic of tep_register_event_handler() API
  tools lib traceevent: Changed return logic of trace_seq_printf() and trace_seq_vprintf() APIs
  tools lib traceevent: Rename struct cmdline to struct tep_cmdline
  tools lib traceevent: Initialize host_bigendian at tep_handle allocation
  tools lib traceevent: Introduce new libtracevent API: tep_override_comm()
  perf tests: Add a test for the ARM 32-bit [vectors] page
  perf tools: Make find_vdso_map() more modular
  perf trace: Fix alignment for [continued] lines
  perf trace: Fix ')' placement in "interrupted" syscall lines
