2023-01-18tools headers: Syncronize linux/build_bug.h with the kernel sourcesArnaldo Carvalho de Melo
To pick up the changes in: 07a368b3f55a79d3 ("bug: introduce ASSERT_STRUCT_OFFSET") This cset only introduces a build time assert macro, that may be useful at some point for tooling, for now it silences this perf build warning: Warning: Kernel ABI header at 'tools/include/linux/build_bug.h' differs from latest version at 'include/linux/build_bug.h' diff -u tools/include/linux/build_bug.h include/linux/build_bug.h Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Maxim Levitsky <mlevitsk@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paolo Bonzini <pbonzini@redhat.com> Link: http://lore.kernel.org/lkml/Y8f0jqQFYDAOBkHx@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2020-04-14tools headers: Synchronize linux/bits.h with the kernel sourcesArnaldo Carvalho de Melo
To pick up the changes in these csets: 295bcca84916 ("linux/bits.h: add compile time sanity check of GENMASK inputs") 3945ff37d2f4 ("linux/bits.h: Extract common header for vDSO") To address this tools/perf build warning: Warning: Kernel ABI header at 'tools/include/linux/bits.h' differs from latest version at 'include/linux/bits.h' diff -u tools/include/linux/bits.h include/linux/bits.h This clashes with usage of userspace's static_assert(), that, at least on glibc, is guarded by a ifnded/endif pair, do the same to our copy of build_bug.h and avoid that diff in check_headers.sh so that we continue checking for drifts with the kernel sources master copy. This will all be tested with the set of build containers that includes uCLibc, musl libc, lots of glibc versions in lots of distros and cross build environments. The tools/objtool, tools/bpf, etc were tested as well.
