tools headers: Synchronize linux/bits.h with the kernel sources
To pick up the changes in this cset: 3c7a8e190bc58081 ("uapi: introduce uapi-friendly macros for GENMASK") That just causes perf to rebuild. Its just some macros going to an uapi header that we now have to grab a copy into tools/ as well. This addresses this perf build warning: Warning: Kernel ABI header differences: diff -u tools/include/linux/bits.h include/linux/bits.h Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paolo Bonzini <pbonzini@redhat.com> Link: https://lore.kernel.org/lkml/ZiwJsFOBez0MS4r9@x1 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
