From fd97d39b0aa49a4beb429aec344604c1b689f089 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 11 Apr 2018 18:03:33 -0300 Subject: Revert "x86/asm: Allow again using asm.h when building for the 'bpf' clang target" This reverts commit ca26cffa4e4aaeb09bb9e308f95c7835cb149248. Newer clang versions accept that asm(_ASM_SP) construct, and now that the bpf-script-test-kbuild.c script, used in one of the 'perf test LLVM' subtests doesn't include ptrace.h, which ended up including arch/x86/include/asm/asm.h, we can revert this patch.
