Merge tag 'perf-urgent-for-mingo-5.2-20190528' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/urgent

Pull perf/urgent fixes:

BPF:

  Jiri Olsa:

  - Fixup determination of end of kernel map, to avoid having BPF programs,
    that are after the kernel headers and just before module texts mixed up in
    the kernel map.

tools UAPI header copies:

  Arnaldo Carvalho de Melo:

  - Update copy of files related to new fspick, fsmount, fsconfig, fsopen,
    move_mount and open_tree syscalls.

  - Sync cpufeatures.h, sched.h, fs.h, drm.h, i915_drm.h and kvm.h headers.

Namespaces:

  Namhyung Kim:

  - Add missing byte swap ops for namespace events when processing records from
    perf.data files that could have been recorded in a arch with a different
    endianness.

  - Fix access to the thread namespaces list by using the namespaces_lock.

perf data:

  Shawn Landden:

  - Fix 'strncat may truncate' build failure with recent gcc.

s/390

  Thomas Richter:

  - Fix s390 missing module symbol and warning for non-root users in 'perf record'.

arm64:

  Vitaly Chikunov:

  - Fix mksyscalltbl when system kernel headers are ahead of the kernel.

    cc-ldoption

	cc-ldoption is used to check if $(CC) when used to link object files

	supports the given option.  An optional second option may be

	specified if first option are not supported.



	Example:

		#arch/x86/kernel/Makefile

		vsyscall-flags += $(call cc-ldoption, -Wl$(comma)--hash-style=sysv)



	In the above example, vsyscall-flags will be assigned the option

	-Wl$(comma)--hash-style=sysv if it is supported by $(CC).

	The second argument is optional, and if supplied will be used

	if first argument is not supported.

	as-instr checks if the assembler reports a specific instruction

	and then outputs either option1 or option2
