tools headers: Remove broken definition of __LITTLE_ENDIAN

2021-07-14T17:39:36Z

The linux/kconfig.h file was copied from the kernel but the line where with the generated/autoconf.h include from where the CONFIG_ entries would come from was deleted, as tools/ build system don't create that file, so we ended up always defining just __LITTLE_ENDIAN as CONFIG_CPU_BIG_ENDIAN was nowhere to be found. This in turn ended up breaking the build in some systems where __LITTLE_ENDIAN was already defined, such as the androind NDK. So just ditch that block that depends on the CONFIG_CPU_BIG_ENDIAN define. The kconfig.h file was copied just to get IS_ENABLED() and a 'make -C tools/all' doesn't breaks with this removal.

Pull perf tool updates from Arnaldo Carvalho de Melo: "Tools: - Add cgroup support for 'perf top' (-G). - Add support for KVM MSRs in 'perf kvm stat' - Support probes on init functions in 'perf probe', to support the bootconfig format. - Improve error reporting in 'perf probe'. - No need to synthesize BUILD_ID records in 'perf inject' if the MMAP2 records have build ids already. - Allow toggling source code ('s' hotkey) in 'perf annotate' in all lines. - Add itrace options support to 'perf annotate'. - Support to custom DSO filters for 'perf script'. Hardware enablement: - Support the HYBRID_TOPOLOGY and HYBRID_CPU_PMU_CAPS features in the perf.data file header. - Support PMU prefix for mem-load and mem-store events, to support hybrid (BIG little) CPUs such as Intel's Alderlake. - Support hybrid CPUs in 'perf mem' and 'perf c2c'. Hardware tracing: - Intel PT now supports tracing KVM guests. - Timestamp improvements for ARM's Coresight. Build: - Add 'make -C tools/perf build-test' entries for libopencsd/CORESIGHT=1 and libbpf/LIBBPF_DYNAMIC=1. - Use bison's --file-prefix-map option to avoid storing full paths when using O= in the perf build. Tests: - Improve the 'perf test' entries for libpfm4 and BPF counters. Misc: - Sync msr-index.h, mount.h, kvm headers with the kernel originals. - Add vendor events and metrics for Intel's Icelake Server & Client" * tag 'perf-tools-for-v5.14-2021-07-01' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (123 commits) perf session: Add missing evlist__delete when deleting a session perf annotate: Allow 's' on source code lines perf dlfilter: Add object_code() to perf_dlfilter_fns perf dlfilter: Add attr() to perf_dlfilter_fns perf dlfilter: Add srcline() to perf_dlfilter_fns perf dlfilter: Add insn() to perf_dlfilter_fns perf dlfilter: Add resolve_address() to perf_dlfilter_fns perf build: Install perf_dlfilter.h perf script: Add option to pass arguments to dlfilters perf script: Add option to list dlfilters perf script: Add dlfilter__filter_event_early() perf script: Add API for filtering via dynamically loaded shared object perf llvm: Return -ENOMEM when asprintf() fails perf cs-etm: Delay decode of non-timeless data until cs_etm__flush_events() tools headers UAPI: Synch KVM's svm.h header with the kernel tools kvm headers arm64: Update KVM headers from the kernel sources tools headers UAPI: Sync linux/kvm.h with the kernel sources tools headers cpufeatures: Sync with the kernel sources tools include UAPI: Update linux/mount.h copy tools arch x86: Sync the msr-index.h copy with the kernel sources ...
