Merge tag 'perf-urgent-for-mingo-4.15-20171218' of... 

Merge tag 'perf-urgent-for-mingo-4.15-20171218' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

- Fix up build in hardened environments, such as fedora 27 (Jiri Olsa)

- Do not include header files from the kernel sources for the s/390 arch,
  fixing the detached tarball building (Arnaldo Carvalho de Melo)

- Allow again using asm.h when building for the 'bpf' clang target,
  guarding x86 specific bits under ifndef __BPF__ (Arnaldo Carvalho de Melo)

- Generate correct debug information for inlined code when generating
  ELF images for JITted java programs (Ben Gainey)
