Arnaldo Carvalho de Melo c13009c1ef perf tests bpf: Remove unused ptrace.h include from LLVM test
The bpf-script-test-kbuild.c script, used in one of the LLVM subtests,
includes ptrace.h unnecessarily, and that ends up making it include a
header that uses asm(_ASM_SP), a feature that is not supported by clang
<= 4.0, breaking that 'perf test' entry.

This ended up leading to the ca26cffa4e ("x86/asm: Allow again using
asm.h when building for the 'bpf' clang target"), adding an ifndef
__BPF__ to the arch/x86/include/asm/asm.h file.

Newer clang versions accept that asm(_ASM_SP) construct, so just remove
the ptrace.h include, which paves the way for reverting ca26cffa4e
("x86/asm: Allow again using asm.h when building for the 'bpf' clang
target").

Wang Nan 7af3f3d55b perf test: Enhance the LLVM tests: add kbuild test
This patch adds a kbuild testcase to check whether kernel headers can be
correctly found.

For example:
  # mv /lib/modules/4.3.0-rc5{,.bak}
  # perf test LLVM

    38: Test LLVM searching and compiling                        : Skip

  # perf test -v LLVM
  ...
  <stdin>:11:10: fatal error: 'uapi/linux/fs.h' file not found
  #include <uapi/linux/fs.h>
          ^
  1 error generated.
  ERROR:	unable to compile -
  Hint:	Check error message shown above.
  Hint:	You can also pre-compile it into .o using:
     		 clang -target bpf -O2 -c -
	 with proper -I and -D options.
  Failed to compile test case: 'Test kbuild searching'
  test child finished with -2
