    perf tests bpf: Remove unused ptrace.h include from LLVM test · c13009c1

    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 ca26cffa ("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 ca26cffa
