tools headers: Update tools's copy of x86/asm headers
tldr; Just FYI, I'm carrying this on the perf tools tree. Full explanation: There used to be no copies, with tools/ code using kernel headers directly. From time to time tools/perf/ broke due to legitimate kernel hacking. At some point Linus complained about such direct usage. Then we adopted the current model. The way these headers are used in perf are not restricted to just including them to compile something. There are sometimes used in scripts that convert defines into string tables, etc, so some change may break one of these scripts, or new MSRs may use some different #define pattern, etc. E.g.: $ ls -1 tools/perf/trace/beauty/*.sh | head -5 tools/perf/trace/beauty/arch_errno_names.sh tools/perf/trace/beauty/drm_ioctl.sh tools/perf/trace/beauty/fadvise.sh tools/perf/trace/beauty/fsconfig.sh tools/perf/trace/beauty/fsmount.sh $ $ tools/perf/trace/beauty/fadvise.sh static const char *fadvise_advices[] = { [0] = "NORMAL", [1] = "RANDOM", [2] = "SEQUENTIAL", [3] = "WILLNEED", [4] = "DONTNEED", [5] = "NOREUSE", }; $ The tools/perf/check-headers.sh script, part of the tools/ build process, points out changes in the original files. So its important not to touch the copies in tools/ when doing changes in the original kernel headers, that will be done later, when check-headers.sh inform about the change to the perf tools hackers.
